Answer:
x =-2
Step-by-step explanation:
log 15 = log(7 - 4x)
The terms inside the log functions must be the same
15 = 7 -4x
Subtract 7 from each side
15-7 = 7-4x-7
8 = -4x
Divide each side by -4
8/-4 =-4x/-4
-2 =x

Answer:
17
Step-by-step explanation:
F(x) = 9x² - 54x - 19 = 9x² - 57x + 3x - 19 = 3x(3x - 19) + 1(3x - 19)
= (3x - 19)(3x + 1)
f(x) = 0 if 3x - 19 =0 or 3x + 1 = 0
3x = 19 or 3x = -1
x = 19/3 or x = -1/3
