number of minutes Tamara could use her phone
each month in order to stay within her budget?
A. 150
B. 271
C. '421
D. 692

c

Step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
