FG=8x+4. If GH=4x+8 and FH=15x-9, then what does FH=?
Mashcka [7]
So 8x+4+4x+8=15x-9

Combine like terms.

12x+12=15x-9

Add 9 to both sides.

12x+21=15x

Subtract 12 from both sides.

21=3x

Divide both sides by 3.

x=7

Now plug in 7 for x in 8x+4.

8(7)+4

56+4

=60

PLEASE HELP ME!!

Take the derivative:
g’(x) = 12x^3 - 24x^2

Set equal to zero and solve:
0 = 12x^3 - 24x^2
0 = 12x^2 (x - 2)

x = 0 or x = 2

Plug back into original
g(0) = 3(0^4) - 8(0^3)
g(0) = 0 - 0
g(0) = 0

g(2) = 3(2^2) - 8(2^3)
g(2) = 3(4) - 8(8)
g(2) = 12 - 64
g(2) = -52

There is an absolute max at (0,0) or when x = 0
