Which function would be produced by a horizontal stretch of the graph of y= Vi followed by a reflection in the I-axis?
y=-21
V
y=2(-2)
=V7(-2)

answer: i believe its b. if you sound out the sentences that sounds wrong.

i wish i could u

step-by-step explanation:

i wish i could u

the correct answers i think are b. and d.

give me brainliest if it is correct!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
