f(x) = 7x − 5

x=5

f(5) = 7(5) -5

f(5) = 35-5

Answer:

30

Step-by-step explanation:

Solve for x:

7 x - 5 = 0

Add 5 to both sides:

7 x + (5 - 5) = 5

Evaluate 7 x - 5 where x = 5:

7 x - 5 = 7×5 - 5

Hint: | Multiply 7 and 5 together.

7×5 = 35:

35 - 5

Hint: | Subtract 5 from 35.

| 3 | 5

- | | 5

| 3 | 0:

Answer:  30
