Answer:

Q'(15, -3)

Step-by-step explanation:

Multiply the coordinates by the scale factor to get the new coordinates.

5 · 3 = 15

-1 · 3 = -3

Therefore, Q'(15, -3).

Answer:

The coordinates of the Midpoint of AB will be: (1/2, 5)

Step-by-step explanation:

Given the points

Finding the midpoint between (-2, 6) and (3, 4)

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-2,\:6\right),\:\left(x_2,\:y_2\right)=\left(3,\:4\right)[/tex]

[tex]M.P=\left(\frac{3-2}{2},\:\frac{4+6}{2}\right)[/tex]

        [tex]=\left(\frac{1}{2},\:5\right)[/tex]

Therefore, the coordinates of the Midpoint of AB will be: (1/2, 5)

Answer:

20 hours

Step-by-step explanation:

52/8 = $6.5/hour

130 / 6.5 = 20

20 hours

6

Step-by-step explanation:

Answer: x=6

Step-by-step explanation: 3(x+2)=24

(3)(x)+(3)(2)=24

3x+6=24

3x+6−6=24−6

3x=18

3x/3=18/3

x=6

Answer:

ofc! :D

Step-by-step explanation:

i- x represents the input

ii- y represents the output

iii- yes, the input (x) is 4 times greater than the output (y)

b just plot them like normal on a coordinate grid :D

Answer:

18 cents per ounce

Step-by-step explanation:

The first step is to identify the unit. In this case, you are told you have 16-ounces. Therefore, your unit is an ounce.

To find the price of one ounce, just divide your price of $2.88 by 16.

Unit rate = $2.88 / 16 = 0.18 or 18 cents per ounce.

Answer:

I will do the first one for you 115/24

Step-by-step explanation:

First find the prime number is of the number on the bottom of the fraction

Second after finding the prime numbers multiple all the times number starting with the bigger number’s prime number, and if the other prime number have a pair dont add them into equation. Ex 8-2 2 2 and 4-2 2 the 8 has 3 (2s) cancelling out the 4’s( 2s) other ex. 6-2 3 and 18- 2 3 3 the 18 has a 2 and 3 cancelling out the 6’s 2 and 3 making it multiple 2x3x3

Third after finding this number at step (2) this is the number at the bottom of the fraction making it easy to do any equations on it

Hope this helps :D

Answer:

What model?

Step-by-step explanation:

Answer:

y = 20x + 280

Step-by-step explanation:

The linear equation that represent your account balance is as follows:

Your friend

y = 25(6) + 250

= 400

And,

You

400 = m(6) + 280

6m = 400 - 280

6m = 120

m = 20

Now the equation of the account balance is

y = 20x + 280

Hence, the linear equation that represent your account balance is y = 20x + 280

Answer:

a.) 94 cm^2

Step-by-step explanation:

3 x 4 = 12

5 x 3 = 15

4 x 5 = 20

12 + 12 + 15 + 15 + 20 + 20 = 94

Answer: 94 cm squared

Step-by-step explanation:

Answer:

A. y - 4 = 3(x + 2)

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line

Plug in the slope and given point:

y - y1 = m(x - x1)

y - 4 = 3(x + 2) is the equation

So, A is the correct answer.

Answer:

B

Step-by-step explanation:

vertical line test means draw lots of vertical lines and see if they pass through two or more points

if they do, the graph is not a function

for example, x= 0 passes through two points

so it is not a function

Answer:

Step-by-step explanation:

by inspection.. ( looking at the graph)  we can see that the slope is down hill. so it's going to be negative and also  slope = rise / run     [rise is negative in this question] soo ... i'm looking carefully to see where the line is crossing the grid marks exactly .. it looks like to me  (-3,1) and (2,-3)   you tell me if that looks right... if it does .. then the rise / run is 4/5  and this is a negative slope  sooo  

- 4/5
