Line qr has undergone a dilation.

the measure of qr is 15 cm, and the measure of q'r' is 52.5 cm. which scale factor was used for the dilation?

a.7

b.7/2

c.2

d.2/7

i think the answer is B

B.7/2

Step-by-step explanation:

QR is 15 cm to  Q'R' is 52.5 cm.

It's an enlargement so SF must be greater than 1

SF = 52.5 / 15

= 3.5

= 7/2

Answer

B.7/2

idk

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
