-8 + 5x - 2 = 20 solve
vaieri [72.5K]

Combining like terms on the left-hand side gives us 5x-10=20. Adding 10 to both sides gives 5x=30, and dividing both sides by 5 gives our answer of \boxed{x=6}.

HELP ASAP ILL GIVE YOU BRAINLEST
stellarik [79]

Answer:

f(x) = (8/3)x(x - 1).

Step-by-step explanation:

The vertex form of the function is

y = a(x - 1/2)^2 - 2/3   where a is some constant.

Now the roots are 0 and 1 so

For  x = 0

0 =  a(-1/2)^2 - 2/3

1/4 a = 2/3

a = 2/3 / 1/4  = 8/3.

So the function is

f(x) = (8/3)(x - 1/2)^2 - 2/3.

3 f(x) = 8(x - 1/2)^2 - 2

= 8(x^2 - x + 1/4) - 2

=  8x^2 - 8x + 2 - 2

3 f(x) = 8x(x - 1)

f(x) = (8/3)x(x - 1).
