Answer:

x = 12

Step-by-step explanation:

Step 1: Define

f(x) = 2x - 7

f(x) = 17

Step 2: Substitute

17 = 2x - 7

Step 3: Solve for x

Add 7 on both sides: 24 = 2x

Divide both sides by 2: 12 = x

Step 4: Check

f(12) = 2(12) - 7

f(12) = 24 - 7

f(12) = 17

I'm asuming you did a typo from a previous quesiton I see that it is a dollar sign
$12 per hour
for 15 hourse, just multiply $12 by 15 because per hour means per 1 hour
15 times $12=$180
answer is $180

Find f(5) please explain

kirza4 [7]

Answer:

-1

Step-by-step explanation:

A function is represented by the following symbol f(x) where f(x) further represents y like this ,

$y=f(x)$

so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?

We can see in the graph when x = 5 the value of y is -1 to be exact so

f(5) = -1

$y=f(x)\\-1 = f(5)\\$
