If f(x) = 5 + 4(x - 4)?,<br> what is f(7)?
grigory [225]

Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112

A. What would be the cost of the Standard Daily Rate plus Mileage plan?
Jobisdone [24]

Answer:

Part a) \$190

Part b) \$315

Part c) Standard Daily Rate plus Mileage plan

Step-by-step explanation:

Part a) What would be the cost of the Standard Daily Rate plus Mileage plan?

Let

y ----> the total cost

x ----> the number of kilometers

we have that

For a Luxury car

y=70+0.30x

For x=400 km

substitute

y=70+0.30(400)

y=\$190

Part b) What would be the cost of the Unlimited Mileage plan?

we know that

The Unlimited Mileage plan for a Luxury car is $105 per day (see the table)

The trip are three days

so

To find the total cost multiply $105 by 3

3(\$105)=\$315

Part c) Which is the better plan?

Compare

\$190 < \$315

therefore

For this trip the better plan is the Standard Daily Rate plus Mileage plan
