Rectangle hijk has vertices h(–5, 2), i(–1, 2), j(–1, 4), and k(–5, 4).without graphing, determine the coordinates of l', m', and n' after lmn has undergone the described transformation. a dilation with a scale factor of 7. *

To do this, multiply each co-ordinate by 7

H(-5, 2) will turn to H'(-35, 14)

etc...

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
