Suppose A has a coordinate of 8 and AB = 3. What are the possible midpoints of AB?
Answer:
The possible midpoints of AB are 6.5 and 9.5
Step-by-step explanation:
Given that the coordinates of A is 8
The length of AB = 3
When A is the maximum coordinates of the two coordinates, A and B, we have;
The midpoint of AB = Coordinates of A - 1/2 × Length of AB
The midpoint of AB = 8 - 1/2 × 3 = 8 - 1.5 = 6.5
The midpoint of AB = 6.5
When A is the minimum coordinates of the two coordinates, A and B, we have;
The midpoint of AB = Coordinates of A + 1/2 × Length of AB
The midpoint of AB = 8 + 1/2 × 3 = 8 + 1.5 = 9.5
The midpoint of AB = 9.5
Therefore, the possible midpoints of AB are 6.5 and 9.5.
Is -3 a natural number a whole number a integer a rational number or irrational number
Answer:
-3 is a rational integer.
Step-by-step explanation:
An integer is a superset of the whole numbers that includes the negated values as well as 0.
A rational number is simply anything that can be expressed as a fraction.
-3 is by these definitions, a negated 3, and any non fractional number can be expressed as a fraction.
-3 is not a natural number, as that is the set of numbers {1, 2, 3, 4, 5, ... etc} and -3 is not a whole number, as that is the set of numbers {0, 1, 2, 3, 4, ... etc}.
And -3 is also not an irrational number since it can be expressed as a fraction.
Thus, -3 is a rational integer.

a rectangle has a height of w^2+3w+9 and a width of w^2+2 express the area of the entire rectangle
Answer:
w⁴ + 3w³ + 11w² + 6w + 18
Step-by-step explanation:
Rectanle area = height * width
area = (w²+3w+9)(w² + 2)
= w²*w² + w²*2 + 3w*w² + 3w*2 + 9*w² + 9*2
= w⁴ + 2w² + 3w³ + 6w + 9w² + 18
= w⁴+ 3w³ + (9w²+2w²) + 6w + 18
= w⁴ + 3w³ + 11w² + 6w + 18
Answer:
w^4 + 3w^3 + 11w^2 + 6w + 18.
Step-by-step explanation:
Area = height * width
= (w^2 + 2)(w^2 + 3w + 9)
= w^2(w^2 + 3w + 9) + 2(w^2 + 3w + 9)
= w^4 + 3w^3 + 9w^2 + 2w^2 + 6w + 18
= w^4 + 3w^3 + 11w^2 + 6w + 18.

What is the slope againnn ?
Answer:
-1/2
Step-by-step explanation:
To find the slope, pick two points on the line, and use the slope formula
( 1,9) and (5,7)
m = (7-9 )/(5-1)
-2/4
-1/2
Answer:
slope = -1/2
Step-by-step explanation:
Find two points on the line that are easy to read. The easiest points to read are points that lie on grid intersections.
For example, use point (1, 9) and point (3, 8).
slope = rise/run
Rise is the vertical distance between points. Up is positive. Down is negative.
Run is the horizontal distance between points. Right is positive. Left is negative.
You need to go from one point to the other points and note the rise and run.
Start at (1, 9).
Go 1 unit down. That is a rise of -1 since you went down 1 unit.
Now go 2 units right. That is a run of +2 since you went 2 units to the right.
slope = rise/run = -1/2
Answer: slope = -1/2
Sara bought a meal in a town that has no sales tax. If she tipped 20% and paid a total of $18.96, what was the original cost of her meal?
Answer: $18.76
Step-by-step explanation:
Let original cost of meal =x
According to question,
x+20%=18.96
x=18.96-20%
x=$18.76
Answer:
original cost of meal = $15.80
Step-by-step explanation:
120% = $18.96 (divide both sides by 120)
1% = $0.158 (multiply both sides by 100)
100% = $15.80

Beakers X and Y contain some water. If 50 ml of water is transferred from Beaker X
to Beaker Y, there will be 3/7 as much water in Beaker X as in Beaker Y. IF 100 ml
of water is transferred from Beaker Y to Beaker X, there will be 4 times as much
water in Beaker X as in Beaker Y. How much water is there in Beaker X?
Answer:
140 ml
Step-by-step explanation:
Let x be the amount of water in Beaker X and y be the amount of water in Beaker Y.
Then we get following equations:
First part
x - 50 = 3/7(y + 50)7x -350 = 3y + 1507x = 3y + 500Second part
x + 100 = 4(y - 100) x + 100 = 4y - 400x = 4y - 500Substitute x in first equation:
7(4y - 500) = 3y + 50028y - 3500 = 3y + 50028y - 3y = 500 + 350025y = 4000y = 4000/25y = 160 mlThen finding x:
x = 4*160 - 500x = 640 - 500x = 140 mlInitial amount of water in Beaker X is 140 ml, in Beaker Y is 160 ml

Answer:
1. 3 − 6n
2. Melody: m Fatima: 3m
3. i. Perimeter = y + 10 + 8
ii. The perimeter is 25 inches when y = 7
Step-by-step explanation:
1. Let the number be represented by n, thus the product of the number and 6 is 6n. Since 3 is less than 6n, therefore: 3 - 6n is the appropriate expression.
2. Let Melody's age be represented by m, Fatima is three times Melody's age implies 3m. So that Melody's age is m, while Fatima's age is 3m.
3. Length of the sides of the triangle in inches are 10, 8 and y.
Perimeter = addition of the length of sides of the triangle
= 10 + 8 + y
When y = 7,
Perimeter = 10 + 8 + 7

Answer:
Solution: Option C
Step-by-step explanation:
Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).
[tex]x^2\:+\:y^2\:+8x\:-\:12y\:+\:43\:=\:0[/tex] (Factor the expression "x² + 8x")
[tex]x^2+8x = x\left(x+8\right)[/tex] (Factor the expression "y² - 12y")
[tex]\:y^2-12y =y\left(y-12\right)[/tex]
That leaves us with the expression [tex]\left(x-\left(-4\right)\right)^2+\left(y-6\right)^2=3^2[/tex], or in other words [tex](x+4)^2 +(y-6)^2 = 9[/tex]. As you can see our solution is option c.

find the coordinates of the other endpoint of the segment of one endpoint is (-2,-7) and midpoint is (6,-10)
Answer:
(14, - 13 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]
let (x₁, y₁ ) = (- 2, - 7) and (x₂, y₂ ) = (x, y)
Using the midpoint formulae equate to the coordinates of the midpoint.
[tex]\frac{1}{2}[/tex] (- 2 + x) = 6 ( multiply both sides by 2 )
- 2 + x = 12 ( add 2 to each side )
x = 14
and
[tex]\frac{1}{2}[/tex] (- 7 + y ) = - 10 ( multiply both sides by 2 )
- 7 + y = - 20 ( add 7 to both sides )
y = - 13
Thus
coordinates of other endpoint = (14, - 13 )

I WILL GIVE BRAINLIEST a scale on a map shows that 2 inches = 25 miles Part A: How many inches on the map = 60 miles? ------------------------------------------------------------------------ Part B: How many miles are represented by 1/4 inch on the map?
Answer:
4.8 in, 3.125 mi
Step-by-step explanation:
This situation models direct proportionality, hence, if one variable increases, the other goes increases as well and vice versa. In this case, the variables are inches and miles.
Part A: Since you multiply 60/25 by 25 to get 60 miles, we know that the value in inches will be 2 * 60/25 = 4.8 inches.
Part B: Since you divide 2 by 8 to get 1/4 inches, we know that the value in miles will be 25 / 8 = 3.125 miles.
You are choosing between two different cell phone plans. The first plan charges a rate of 26 cents per minute. The second plan charges a monthly fee of $39.95 plus 12 cents per minute. Let t be the number of minutes you talk and C1 and C2 be the costs (in dollars) of the first and second plans. Give an equation for each in terms of t, and then find the number of talk minutes that would produce the same cost for both plans (Round your answer to one decimal place). C1= C2= If you talk for minutes the two plans will have the same cost.
Answer:
285.28571429 minutes
Step-by-step explanation:
Let us represent
The number of minutes you talk = t
C1 = Cost in dollars of the first plan
C2 = Cost in dollars of the second plan
First plan
The first plan charges a rate of 26 cents per minute
Converting cents to dollars
100 cents = 1 dollars
26 cents =
26/100 cents
=$ 0.26
C1 = $0.26 × t
C1 = 0.26t .......... Equation 1
Second Plan
The second plan charges a monthly fee of $39.95 plus 12 cents per minute
Converting 12 cents to dollars
100 cents = 1 dollars
12 cents =
12/100
= $0.12
C2 = $39.95 + 0.12t........Equation 2
Find the number of talk minutes that would produce the same cost for both plans
We would Equate C1 to C2
C1 = C2
0.26t = $39.95 + 0.12t
Collect like terms
0.26t - 0.12t = $39.95
= 0.14t = $39.95
Divide both sides by 0.14
= t = $34.95/0.14
t = 285.28571429 minutes
Therefore, the number of talk minutes that would produce the same cost for both plans is 285.28571429 minutes.
The life expectancy of a monkey is 15 years, an African elephant 35 years, a beaver 5 years, and a grizzly bear 25 years. Write a relation that describes this information. Determine its domain and range.
Answer:
The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35
Step-by-step explanation:
The given parameters are;
The life expectancy of a monkey = 15 years
The life expectancy of an African elephant = 35 years
The life expectancy of a beaver = 5 years
The life expectancy of a grizzly bear = 25 years
Therefore, if the life expectancy of a beaver = X, we have;
The life expectancy of a monkey = 3 × The life expectancy of a beaver = 3·X
The life expectancy of a beaver = X
The life expectancy of an African elephant = 7 × The life expectancy of a beaver = 7·X
The life expectancy of a grizzly bear = 5 × The life expectancy of a beaver = 5·X
Therefore;
The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35.
Answer:
Relation = {(Monkey, 15), (African elephant, 35), (Beaver, 5), (Grizzly bear, 25)}
Domain = {Monkey, African elephant, Beaver, Grizzly bear}
Range = {5, 15, 25, 35}
Step-by-step explanation:
1. RelationRelation is just (x,y).
{(Monkey, 15), (African elephant, 35), (Beaver, 5), (Grizzly bear, 25)}
2. DomainI like to put domain as least ---> greatest, but in this case, it's just the names
{Monkey, African elephant, Beaver, Grizzly bear}
3. RangeThe numbers.
