Solve for x. 3(3x - 1) + 2(3 - x) = 0 = 0

1 answer:

4 0

If you would like to solve the equation 3 * (3 * x - 1) + 2 * (3 - x) = 0, you can calculate this using the following steps:

3 * (3 * x - 1) + 2 * (3 - x) = 0
3 * 3 * x - 3 * 1 + 2 * 3 - 2 * x = 0
9 * x - 3 + 6 - 2 * x = 0
7 * x + 3 = 0
7 * x = - 3 /7
x = - 3/7

The correct result would be - 3/7.

Answer

f(-4) = 125, g(6) = -13

Step-by-step explanation:

all of those symbols might look really scary, but really all the problem is asking you to do is substitute -4 into the x in f(x) and 6 into the x in g(x) -- basically, f(-4) = $-2((-4)^{3}) - 3$ = 125, and g(6) = $-2(6) - 1$ = -13. there are your answers!
