Helppppppp pleaseeeeee

All you have to do is plug in the number for x, and find y. I will write this out as if in that chart you have shown.

x                            y = 9 - 3x                                    y

_______________________________________

0                           y = 9 - 3(0)                                  9

1                            y = 9 - 3(1)                                   6

2                           y = 9 - 3(2)                                  3

3                           y = 9 - 3(3)                                  0


Hope that helps!!

I really need help with this one
Novay_Z [31]

Answer:

28

Step-by-step explanation:

Since B is the midpoint of AC, that means AB = BC. That means 3x+4 = 5x-6. We can now set up an equation to solve for x:

3x+4 = 5x-6

3x+10 = 5x

10 = 2x

x = 5

Now that we know what x is, we can just plug x into the expression of AB and multiply it by 2:

(3*(5)+4)*2

=(15+4)*2

=19*2

=28

(side note: we could have plugged x into the expression of BC as well, but in this case plugging it into AB tends to be easier to solve)

Therefore, the length of AC is 28.
