Does anyone know how to solve this?

Answer:

b = -125/9

Step-by-step explanation:

1 + log5 ( -9b) = 4

Subtract 1 from each side

1 -1+ log5 ( -9b) = 4-1

log5 ( -9b) = 3

Raise each side to the base 5

5^ log5 ( -9b) = 5^3

This will cancel the log5

-9b = 125

Divide each side by 9

-9b/-9 = 125/-9

b = -125/9

1) Given the function f(x) = 2x -3, evaluate f(3).

igomit [66]

Answer:

1) $f(3) = 3$

2) $x = 2$

Step-by-step explanation:

Given:

$f(x) = 2x -3$

Evaluating $f(3)$ :

$f(3) = 2(3) -3 \\ f(3) = 6 -3 \\ f(3) = 3$

Solving for $f(x) = -1$ :

$2x -3 = 1 \\ 2x -3 +3 = 1 +3 \\ 2x = 4 \\ \frac{2x}{2} = \frac{4}{2} \\ x = 2$
