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

after simplifying it i got: -36.25 as my answer. hope that !

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!

look at the picture.

1.

ef : ab = 2 : 3

gf : cb = 2 : 3

gh : cd = 2 : 3

he : da = 2 : 3

2.

∠a ≅ ∠e

∠b ≅ ∠f

∠c ≅ ∠g

∠d ≅ ∠h

3.

use pythagorean theorem:

the length of the abcd trapezoid sides:

|ab| = 3 cm

|bc| = 10 cm

|cd| = 3(3) cm = 9 cm

|da| = 8 cm

the perimeter of abcd = 3 + 10 + 9 + 8 = 30 cm

the ratio of perimeters of the tarapezoids is equal 2 : 3.

substitute:

      cross multiply

      divide both sides by 3

x = 1/2

step-by-step explanation:

hope this !
