Which graph matches the equation ?

Pretty sure it's the first one. It's the only one with the correct y-intercept and has a positive slope.

This is in fancy form, so you want to simplify it:

y = 3/4(x+4) - 6

Multiply it all,

y = 3/4x + 3/4(4) - 6

y = 3/4x + 3 - 6

y = 3/4x - 3

The first one matches.

i just took the test, the correct answer is .. 31.5 in.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
