Answer:

1.6

Step-by-step explanation:

To find the scale factor, we compare the image size to the pre-image size.

R'S' = 8 and RS = 5; this makes the scale factor 8/5, which is 1.6.

1.6 is the scale factor. 8÷5=1.6
1.6×5=8 hope that helps.

9 – 2k = 25 what is k

worty [1.4K]

Answer:

k = - 8

Step-by-step explanation:

Subtract 9 from both sides to get the constants on one side and the variables on the other

9 - 2k = 25

- 2k = 25 - 9

Simplify

- 2k = 16

Divide by -2 on both sides to isolate the variable, then simplify once more.

- 2k/ -2 = 16/ -2

k = 16/ -2

k = -8
