Given f(x) - 3x= 1 and g(x) - 2x-3, for which value of x does g(x)= f(2)?
alexira [117]

Answer:

Best Answer:  f(x) = 3x - 1, g(x) = 2x - 3

f(2) = 3(2) - 1 = 6 - 1 = 5.

2x - 3 = 5

2x = 8

x = 4. This value ensures g(x) = f(2).

Value of 4g + 5h when g=1 h=4
GaryK [48]
So pretty much, 4g is 4 times g right? taking this into consideration, replace g with x1 and h with x4. Then you get 4 x 1 + 5 x 4. Since you're always supposed to multiply and then add (left to right), it would equal 4 + 20 which is 24. Good luck on your test.
