If y = 2x + 7 were changed to y = . x+ x+7, how would the graph of the new
function compare with the original?
A. It would change orientation and slant down.
Х
B. It would be steeper.
C. It would be shifted down.
O D. It would be less steep.
X Incorrect

okay so 15.15 *()5: +5/6

step-by-step explanation:

29 is the correct answer

step-by-step explanation:

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.
