A homeowner's electric bill was $94.23 last month. How many kilowatt hours (to the nearest kilowatt hour) were used if the electric company charges $0.1374 per kilowatt-hour plus a basic customer fee of $5.54 per month?
Let x represent the number of kilowatt-hours that were used. Choose the correct equation below. Solve and round to the nearest integer.
A. 5.54-0.1374x=94.23
B. 0.1374x+94.23=5.54
C. 0.1374x+5.54=94.23
D. 0.1374x-5.54=94.23

645 kilowatt-hours

Step-by-step explanation:

Let x represent the number of kilowatt-hours that were used.

if the electric company charges $0.1374 per kilowatt-hour plus a basic customer fee of $5.54 per month, it means that the total charge for x kilowatt-hours used in a month is

5.54 + 0.1374x

The homeowner's electric bill was $94.23 last month. Therefore, the equation would be

0.1374x+5.54=94.23

0.1374x = 94.23 - 5.54

0.1374x = 88.69

x = 88.69/0.1374

x = 645

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
