In 2010, the average cost of electricity was 11.54 cents per kilowatt hour. In 2014, the average cost of electricity was 12.52 cents per kilowatt hour.
Which function models the average retail price of electricity, f(x), in cents per kilowatt hour, x years after 2010?
f() = 0.98x + 4.00
f(x) = 0.245x + 11.54
f(x) = 0.738x + 11.54
f(x) = 4.082x + 1962.89

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

i have no idea just need points sorry

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
