16. 15 = –11b + 4 what is b

b=-1

Step-by-step explanation:

First you have 15= -11b +4

You want to subtract 4 from both sides, so on the left side you get 11 and on the right side you only have -11b because 4-4 cancels out and gets you 0.

11=-11b

Then divide both sides by -11 and the right side equals b and the left side equals -1. So, b = -1.

step-by-step explanation:

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
