Hannah looked at her electricity bill last month and saw that she was charged $99 for 600 kWh (kilowatt-hours) of electricity. This month her bill was $118.50 for 750 kWh. Write a linear function that models her monthly electricity bill as a function of electricity usage.

f(x)= __x+__

What would be the cost of using 1000 kWh?
a.) 158
b.) 180
c.) 173
d.) 151

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

answer

step-by-step explanation:

$113.42

i hope that is right.

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
