F(x) = -7x²y
g(x) = x - 5y
h (x) = 4x^2 – 3x + 2y
What is g (x) + h (x) ?

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
