Answer:

1. C

2. C

Step-by-step explanation:

1. 5x+12=57

Subtract 12 from both sides

5x=45

Divide both sides by 5

x=9

2.  7-4x=12-3x

Combine like terms =

-4x+3x=-12-7

x=-12-7

x=19

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of (f/g)(5)?
Romashka [77]
<h2>Answer:</h2>

d. \ \boxed{270}

<h2>Step-by-step explanation:</h2>

In this exercise we need to make a division and evaluate the new function at x=5. so we have two functions, namely:

f(x)=7+4x \ and \\ \\ g(x)=\frac{1}{2x}  

Therefore:

f(5)=7+4(5)=27 \\ \\ g(5)=\frac{1}{2\times 5}=\frac{1}{10}

So:

(f/g)(5)=\frac{27}{\frac{1}{10}}=270

MAVERICK [17]

We have been given that Marcus works for 26 hours each week and 48 weeks each year.

Thus in a year he works for 26 \times 48 = 1248 hours.

Now, we have been given that Marcus earns $8.40 per hour.

Therefore, in 1248 hours, he earns

1248 \times 8.40\\&#10;\\&#10;=\$ 10483.2

Marcus has to pay tax if he earns more than $10,000. Now we have calculated that he earns $ 10483.2  which is higher than $10,000.

Therefore, Marcus has to to pat tax.
