Answer:

7) (f+g)(x) = 4^x +5x -5

8) (f-g)(x) = 4^x +x +5

Step-by-step explanation:

7) add the two expressions.

(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)

(f+g)(x) = 4^x +5x -5

8) subtract g(x) from f(x).

(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5

(f-g)(x) = 4^x +x +5

22 Solve for x. 3x - 5 = 10 x equals..... help

kramer

Answer:

$x = 5$

Step-by-step explanation:

$3x - 5 = 10$

We want to isolate the x.

$3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5$

$3x = 15$

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

$\frac{3x}{3} \;=\;\frac{15}{3}$

$x = 5$
