Question

example of word problem in linear equation and its solution

Answer 1

Answer:

Hannah's electricity company charges her $0.11 per kWh (kilowatt-hour) of electricity, plus a basic connection charge of $15.00 per month. Write a linear function that models her monthly electricity bill as a function of electricity usage.

Step-by-step explanation:

the bill is $15.00 . So, the y -intercept is 15

The rate of change is 0.11

.That is, for each increase of x by 1 unit (in this case, kilowatt-hours), there is an increase in y by 0.11

Substitute in the slope-intercept form y=mx+b .

y=0.11x+15
