Answer:
[tex]M=(-\frac{1}{2},4)[/tex]
Step-by-step explanation:
The midpoint formula is given by:
[tex]M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Let (2,2) be x₁ and y₁ and let (-3,6) be x₂ and y₂. Therefore:

If 3x - 8= -2, find the value of x - 6.
Answer:
x-6 = -4
Step-by-step explanation:
3x - 8= -2
Add 8 to each side
3x - 8+8= -2+8
3x = 6
Divide by 3
3x/3 = 6/2
x =2
We want to find x-6
2-6 = -4
Answer: - 4
Step-by-step explanation:
3x - 8 = -2
3x = -2 + 8
3x = 6
x = 6/3
x = 2
so, therefore x - 6 => 2 - 6 = -4
i need help , what’s the answer ?
Answer:
D,
Step-by-step explanation:
that's because you only factorise when you have a common factor, ax-3b cannot be factorised because they have nothing in common so it is wrong to use x to factorise it. If you want to be sure that it is not factorisable, try expanding it and you'll see that you will not get the same answer.
Horatio went to the movies and spent $15 on his ticket and snacks. If the snacks cost $8, how much did his ticket cost? -Answer?
Answer:
$7
Step-by-step explanation:
t = ticket price
We know the total cost of the ticket and snacks was $15, and just the snacks were $8 so:
t + $8 = $15
To find the amount of the ticket, subtract $8 from each side
t + $8 - $8 = $15 - $8
The $8 cancels and you're left with
t = $7
So the ticket costs $7
The remaining cost after the snack cost is the cost of the movie ticket and it is $7.
What is subtraction?To subtract in mathematics is to take something away from a group or a number of objects.
In a different sense, subtraction refers to a mathematical procedure where two values will be subtracted to produce a new value.
Total spent = cost of snacks + cost of a movie ticket
Given that,
Total spent = $15
Cost of snacks = $8
So,
15 = 8 + cost of movie ticket
Cost of movie ticket = 15 - 8 = $7
Hence "The remaining cost after the snack cost is the cost of the movie ticket and it is $7".

-30=5k+5 solve for k
Answer:
The answer is -7
5k=-30-5.
5k=-35.
k= -7.
Hi there! Hopefully this helps!
---------------------------------------------------------------------------------------------------
Answer: [tex]\boxed{k = -7}[/tex] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[tex]-30=5k+5[/tex]
Swap sides so that all variable terms are on the left hand side.
[tex]5k+5=-30[/tex]
Subtract 5 from both sides.
[tex]5k=-30-5[/tex]
Subtract 5 from −30 to get −35.
[tex]5k=-35[/tex]
Divide both sides by 5.
[tex]k=\frac{-35}{5}[/tex]
Divide −35 by 5 to get, you guessed it, -7!You can also do "5(-7) + 5 = ??" For proof.
25=19+k. What’s the answer?
Answer:
k=6
Step-by-step explanation:
25=19+k
Subtract 19 from each side
25-19=19-19+k
6 = k
Answer:
k = 6
Explanation:
to find the value of k in the equation provided, you must subtract nineteen from both sides. this will isolate the variable.
25 = 19 + k
25 - 19 = 19 - 19 + k
6 = k
k = 6
therefore, the value of the variable k in 25 = 19 + k is 6.
TIMED QUESTION!!!!!!!
Answer: (2 1/2, 0) (the last option)
Step-by-step explanation:
I guess the function is:
f(x) = (2 1/2) - (3 1/2)*x
now, the rule for f-1(x) that we know is:
f-1( f(x) ) = x.
So if we want to find the x-intercept of f-1(x), we must evaluate it in f(0)
f-1(f(0)) = 0.
And we have that f(0) = (2 1/2) - (3 1/3)*x = 2 1/2
This means that the x-intercept of f-1(x) will be when x= 2 1/2, so the intercept is:
(2 1/2, 0)

Fill in the blank with a constant, so that the resulting quadratic is the square of a binomial. \[x^2 + \dfrac{4}{5}x + \underline{~~~~}\]
Answer:
4/25Step-by-step explanation:
Given the incomplete quadratic equation [tex]\[x^2 + \dfrac{4}{5}x + \underline{~~~~}\][/tex], we are to complete it so that the result will be the square of a binomial. To do that, we will use the completing the square method.
Completing the square method is a way of completing a quadratic equation by solving for a constant to add that will make the quadratic equation a perfect square of a binomial.
To get the constant term using the method, we will take the square of the alf of the coefficient of x in the equation given.
Coefficient of x = 4/5
half of the coefficient of x = 1/2(4/5)
half of the coefficient of x = 4/10 = 2/5
Square of the half of the coefficient of x = (2/5)²
Square of the half of the coefficient of x = 4/25
Hence the constant that we will use to complete the equation to make if a square of a binomial is 4/25
The equation will become:
[tex]= \[x^2 + \dfrac{4}{5}x +\dfrac{4}{25} \\\\= \[x^2 + \dfrac{4}{5}x +(\dfrac{2}{5})^2\\\\= (x +\dfrac{2}{5})^2[/tex]
Hence the constant value that will make the resulting quadratic the square of a binomial is 4/25
Answer:
4/25
Step-by-step explanation:
Suppose the quadratic is the square of the binomial $x+c.$ We have $(x+c)^2 = x^2+2cx + c^2.$ Comparing the linear term of $x^2 + 2cx+c^2$ to the linear term of $x^2 + \frac{4}{5}x + \underline{~~~~},$ we have $2c = \dfrac{4}{5},$ so $c = \dfrac{2}{5}.$ Therefore, the constant term is
\[c^2 = \left(\dfrac{2}{5}\right)^2 = \boxed{\frac{4}{25}}.\]
Why is the sum of a rational number and a irrational number always irrational
Answer:
A rational number is a number able to be put into a fraction, an irrational number is not able to be. Therefore, when adding the two, the rational and the irrational will be irrational. For example, 2 is a rational number, and 1.8903 is irrational. If you add the two, you will get 3.18903, which is unable to be put into a fraction.

Old Mc Donald raises ducks and cows. The animals have a total of 100 heads and 354 feet. How many ducks and how many cows does Old Mc Donald have?
Answer:
The number of ducks Old Mc Donald raises are 23 and the number of cows Old Mc Donald raises are 77.
Step-by-step explanation:
We are given that Old Mc Donald raises ducks and cows. The animals have a total of 100 heads and 354 feet.
Let the number of ducks Old Mc Donald raises be 'x' and the number of cows Old Mc Donald raises be 'y'.
So, according to the question;
The first condition states that the animals have a total of 100 heads, that means;[tex]x+y=100[/tex]
[tex]x=100-y[/tex] -------------------- [equation 1]
{because one head of a duck and one head of cow}
The second condition states that the animals have a total of 354 feet, that means;[tex]2x+4y=354[/tex]
[tex]x+2y=177[/tex] --------------- [equation 2]
{because there are two feet of a duck and four feet of cow}
Now, putting the value of x in equation 2 we get;
[tex]100-y+2y=177[/tex]
[tex]y=177-100[/tex]
y = 77 cows
Putting this value of y in equation 1 we get;
x = 100 - y
x = 100 - 77 = 23 ducks
Hence, the number of ducks Old Mc Donald raises are 23 and the number of cows Old Mc Donald raises are 77.

x + 2y = 13x - y = 17From the first equation we get:
x = 1 -2ySubstitute x in the second equation, find y:
3x - y = 173*(1-2y) - y = 173 - 6y - y = 17-7y = 17 - 3-7y = 14y = -14/7y = -2Find x:
x = 1 - 2y x = 1 - 2*(-2)x = 1 + 4x = 5A city council consists of 8 members. Of the 3 men on the committee, 1 has a bachelor's degree and the other 2 have master's degrees.

A new community sports complex is being build in Madison. The perimeter of the rectangular playing field is 466 yards. The length of the field is 7 years less than quadruple the width. What are the dimensions of the playing field?
Answer:
The dimensions of the field is 185 yards by 48 yards
Step-by-step explanation:
Here, we are interested in calculating the dimensions of the field.
Let the width of the field be x yards
From the question, we are made to know that the length of the field is 7 yards less than quadruple ( 4 times) the width
So mathematically, the length of the field will be ;
(4x -7) yards
The perimeter of the field mathematically is:
2(l + b)
Thus;
2(x + 4x- 7) = 466
2(5x -7) = 466
divide both side by 2
5x - 7 = 466/2
5x - 7 = 233
5x = 233 + 7
5x = 240
x = 240/5
x = 48 yards
Length of field is; 4x -7 = 4(48) -7 = 192 - 7 = 185 yards

Multiplying a number by which of the following would result in a smaller number?
O 100
O 101
O 102
10-1
Answer:
10^(-1)
Step-by-step explanation:
Recall that a value that is multiplied by a number that is between 0 and 1 will result in a number that is smaller than the original number.
the first 3 are all greater than 1, hence will result in a greater value if when multiplied with another number.
The last one is 10^(-1) = 0.1
Anything multiplied by 0.1 will result in a value that is 1/10th of the original value.
Hence this is the answer.
