Answer:

Step-by-step explanation:

vertex formula = a(x-h)^2 + k

vertex is (h, k) so (-1, -4) means

y = a(x+1)^2-4

passes through (1, 8) so when x = 1 and y = 8

8 = a(1+1)^2-4 = 4a - 4

4a = 4

a = 1

How do i solve this?<br> 2+4x=2(2x+1)

IgorC [24]

Answer:

Infinitely many solutions (or 2=2 which isnt related)

Step-by-step explanation:

2+4x=4x+2

Distribute the 2 to the numbers inside.

Secondly, Minus the 4x on the right side and also minus the 4x on the right side.

You would end up with 0x.

The answer would be 2=2, but the real answer would be "infinitely many solutions."

If your teacher thinks this is wrong, I don't know what else. I could be wrong but really, I don't care.
