Answer:
3 units left 7 units down
Step-by-step explanation:
if the sign is inside the bracket opposite sign
if the sign is outside the bracket leave it as it is
so (x+3)=0 which means x= -3 so 3 units left since it is on x axis. 7 is on y axis and since it is negative so 7 units down.
Write an equation in slope-intercept form for the line that passes through (3, 1) and (1,2).
The equation of the line that passes through (3, 1) and (1,2) in slope intercept form is y = - 2 / 2 x + 5 / 2.
How to find equation of a line?The equation of a line can be represented in different form such as slope intercept form, point slope form, standard form and general form.
Therefore, let's write the equation of a line that passes through (3, 1) and (1, 2).
using slope intercept form,
y = mx + b
where
m= slopeb = y-interceptTherefore, let's find slope
m = 2 - 1 / 1 - 3
m = 1 / - 2
m = - 1 / 2
Let's find y-intercept using (1, 2)
2 = - 1 / 2(1) + b
b = 2 + 1 / 2
b = 5 / 2
Therefore, the equation is y = - 2 / 2 x + 5 / 2

Assuming the prices for cat and dog food have not changed over the past two weeks, find and solve the system of equations which can be used to determine the cost of a bag of cat food, c, and the cost of a bag of dog food, d.
c=cost of a bag of cat food
d=cost of a bag of dog food
Write Two Equation
?
?
One bag of cat food costs $6 and one bag of dog food costs $9.
What is system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
The problem states that c equals the cost of bag of cat food and d equals the cost of bag of dog food.
Last week she paid $117 for 6 bags of cat food and 9 bags of dog food.
Therefore, the equation becomes,
6c + 9d = 117 ..(1)
This week she paid $87 for 4 bags of cat food and 7 bags of dog food.
Therefore, the equation becomes,
4c + 7d = 87 ..(2)
Now to solve the system of equations
To solve the first equation for c.
6c + 9d = 117
6c = 117 - 9d
[tex]c = \frac{117}{6}-\frac{9d}{6}[/tex]
Plug value of c in equation (2).
[tex]4(\frac{117}{6}-\frac{9d}{6}) +7d = 87\\78 - 6d + 7d = 87\\d = 87-78\\d = 9[/tex]
Plug d = 9 in equation (1)
6c + 9(d) = 117
6c + 9(9) = 117
6c + 81 = 117
6c = 117 - 81
6c = 36
c = 6
Hence, one bag of cat food costs $6 and one bag of dog food costs $9.

A room is 12 m long,10m broad and 6 m high. It has a door of size 1m×2m and a windows of size 2m × 1.5m. Calculate the cost of plastering the walls at the rate of Rs 15/m².
The cost of plastering the rectangle walls at rate of Rs.15/[tex]m^2[/tex] is Rs.5565.
What is rectangle?
With four sides, four corners, and four right angles (90°), a rectangle is a closed 2-D object. A rectangle's opposing sides are equal and parallel. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The opposite sides of a quadrilateral are equal and parallel, and all the angles are equal. Around us, there are several rectangle-shaped items. Two dimensions, the length and breadth, define each rectangle shape. The width and length of a rectangle are its longer and shorter sides, respectively.
Given,
Length of room =12m
Breadth of room =10m
Height of room =6m
So, Area of four walls =2(l+b)×h
=>area of four wall=2(12+10)×6=264[tex]m^2[/tex]
Now Area of 2 doors and 3 windows =(2×1×2+3×2×1.5)
=> area of 2 doors and 3 windows = 13[tex]m^2[/tex]
Area of ceiling =l×b=12×10=120 [tex]m^2[/tex]
Thus, total area for plastering =(264−13+120)= 371[tex]m^2[/tex]
Hence, the cost of whitewashing =Rs.(371×15)=Rs.5565.

A standard deck of playing cards has 4 different suits (hearts, spades, clubs and diamonds) and 13 different ranks for the cards (ace, 2-10, jack, queen, king). In a poker game you are dealt a hand of 5 cards.
How many ways are there to get dealt exactly a single pair? A pair is a hand with two cards of the same rank. (so two pairs, three of a kind, four of a kind, full house etc. aren't included)
The number of ways that there are to get dealt exactly a single pair is; 6,589,440 ways
What is the probability of Selection?The combination in probability selection is defined as a method where we count the number of ways a certain number of objects can be arranged in "n" different ways. If the number of different objects are "n", then it means that the number of ways that we can select "r" number of different objects is expressed as:
nCr = n!/(r!(n - r)!)
The total number of cards that we have in a deck of cards = 52.
There total number of different cards are 13 in number and this tells us that we can possibly have a pair of any one of the 13 cards. There are also 4 cards of the same rank and this means that the number of ways of selecting two cards of the same rank is; 4C2 = 6 ways
After selecting a card for the pair, we have 48 different cards as an option for the third card. Thereafter, we will have a total of 44 cards as an option for the fourth card and then 40 cards will be an option for the fifth card (due to the fact that none of the cards can be of same rank except for the pair of cards).
Therefore, the total number of ways that we can deal with exactly a single pair can be expressed as:
Number of ways = number of ways for the pair × number of ways for the third card × number of ways for the fourth card × number of ways for the fifth card
Plugging in the relevant values gives;
Number of ways = (13 × 6) × 48 × 44 × 40
= 6,589,440 ways

The heights of adult men in America are normally distributed, with a mean of 69.2 inches and a standard deviation of 2.64 inches. The heights of adult women in America are also normally distributed, but with a mean of 64.2 inches and a standard deviation of 2.53 inches.
If a man is 6 feet 2 inches tall, his z-score is equal to 1.82.
If a woman is 5 feet 10 inches tall, her z-score is equal to 2.92.
The 5 feet 10 inches American woman is relatively taller.
What is a z-score?In a normal distribution, the z-score of a given sample score can be calculated by using this formula:
Z-score = (x - μ)/σ
Where:
σ represents the standard deviation.x represents the sample score.μ represents the mean score.Next, we would convert the height in feet to inches as follows:
American man = 6 × 12 + 2 = 74 inches.
American woman = 5 × 12 + 10 = 70 inches.
For the American man's z-score, we have:
Z-score = (74 - 69.2)/2.64
Z-score = 4.8/2.64
Z-score = 1.82
For the American woman's z-score, we have:
Z-score = (70 - 64.2)/2.53
Z-score = 5.8/2.53
Z-score = 2.92
Therefore, the 5 feet 10 inches American woman is relatively taller because she has a higher z-score (2.92 > 1.82).

75 less than the product of 30 and a number is -225. What is the number?
Answer:
The Number is -5
Step-by-step explanation:
We will form the Equation and solve for the Number
Let the Number be x
Product of 30 and a Number = 30x
75 less than the Product of 30 and a Number = 30x - 75
75 less than the Product of 30 and a Number is -225
Then 30x - 75 = -225
Now solve for x (the Number)
add 75 for both sides
30x = -225 + 75 = -150
Divide both sides by 30
x = -150 / 30 = -5

Answer:
y=1/2x-9/2
Step-by-step explanation:
First you want to find the slope by doing -2-(-1)/5-7
Therefore the slope is 1/2
Next you want to add in any set of points, either (5, -2) or (7, -1)
Substitute the x- point in place of x and the y in place of y in y=1/2x+b
Once you do this you should get -2=1/2(5)+b
You should get -2=2 1/2+b
Then subtract 2 1/2 from -2
You should get -4 1/2
Once you have the slope and y- intercept you can put together your problem
y=1/2x-4 1/2
don't forget to convert, y=1/2x-9/2

What is an equation?
An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.
Let x be the number of tongue depressors.
Let y be the number of Band-Aids
Convert cents to dollars
1 cent = $0.01
So, 4 cents = 0.01*4 = $0.04
8 cents = 0.01* = $0.08
The materials are worth $12.48 .
This means, 0.04x+0.08y=12.48......(1)
There are 184 individual packages in total.
This means, x+y=184.......(2) => x=184-y.....(3)
Substitute (3) in (1),
0.04(184-y)+0.08y=12.48
7.36-0.04y+0.08y=12.48
=> y= 128
(3) => x=184-128=56
So, the number of tongue depressors = 56

How to rewrite an expression without the summation notation?
Summation notation is used to write a very long sum (of elements) in a very concise manner. It is also called Sigma notation
Given:
[tex]\displaystyle \sum\limits_{i = 1}^n \frac{12k(k-1)}{n^{3} }[/tex]
Below are the useful summation formulas you will need in order to rewrite the expression without the summation notation:
[tex]\displaystyle \sum\limits_{i = 1}^n i = \frac{{n\left( {n + 1} \right)}}{2}[/tex]
[tex]\displaystyle \sum\limits_{i = 1}^n {{i^2}} = \frac{{n\left( {n + 1} \right)\left( {2n + 1} \right)}}{6}[/tex]
Where i is a variable
Since 12 and n are constants, we can rewrite the given equation as follows:
[tex]\displaystyle \sum\limits_{i = 1}^n \frac{12k(k-1)}{n^{3} } = \displaystyle \frac{12}{n^{3} } \displaystyle\sum\limits_{i = 1}^n k(k-1)[/tex]
[tex]= \displaystyle \frac{12}{n^{3} } \displaystyle\sum\limits_{i = 1}^n k(k-1)[/tex]
[tex]= \displaystyle \frac{12}{n^{3} } \displaystyle\sum\limits_{i = 1}^n (k^{2}-k)[/tex]
[tex]= \displaystyle \frac{12}{n^{3} } ( \displaystyle\sum\limits_{i = 1}^n k^{2} - \displaystyle\sum\limits_{i = 1}^n k )[/tex]
Using the formula, we have:
= 12/n³ ( n(n+1)(2n+1)/6 - n(n+1)/2 ) Factorise n(n+1) out
= 12n(n+1)/n³ ( (2n+1)/6 - 1/2 )
= 12(n+1)/n² ( (2n+1-3)/2 )
= 12(n+1)/n² ( (2n-2/6) )
= 2(n+1)/n² (2n-2)
= ( (2n+2)(2n-2) )/n²
= (4n² - 4)/n²
= 4(n² - 1)/n²

-1.5 is the difference in the sequence
How determine the difference in a sequence?
An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms are the same.
The difference is usually called the common difference. For example, the sequence 3, 6, 9, 12 have a common difference of 3 i.e. 6-3 = 3 or 9-6 = 3
Given: the sequence 4.5,3,1.5,0
The difference = 3 - 4.5 = -1.5 or 1.5-3 = -1.5
Note: You can pick any two consecutive terms to get the difference
Therefore, the difference in the sequence is -1.5

determine the midpoint of the line segment connecting (6,-5) and (-1,-6)
The midpoint of the line joining (6,-5) and (-1,-6) is (-5/2,-11/2).
How to determine the midpoint of the line joining two points (a,b) and (p,q)?
To get the midpoint of the line joining two points (a,b) and (p,q), we first have to add the x coordinates of two points and divide it by 2. So the midpoint's x coordinate will be (a+p)/2 . Similarly, we have to do the same with y. Then the midpoint of the line joining two points (a,b) and (p,q) will be [(a+p)/2,(b+q)/2}.
To get the midpoint of (6,-5) and (-1,-6) , first, we have to add the x coordinates and divide it by 2 . And have to do the same with y.
so, the midpoint will be [(6+(-5)]/2,[-5+(-6)]/2.
Hence ans will be ,(-5/2,-11/2)

There are 284 number of students and 152 number of adults.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
The ratio of teachers to students on a field trip is 2:13
Let x be the number of adults
If there are 132 more students than adults on the field trip, then 132+x
To find the number of adults and number of students formulate a equation as below
2/13=(x+132)/x
Apply cross multiplication
2x=13(x+132)
Apply distributive law on RHS
2x=13x+1716
11x=1716
Divide both sides by 11
x=152
x+132=152+132=284
Hence there are 284 number of students and 152 number of adults.
