Solve 3x - 7y = 21 for y. what equation form is the original equation in. once it is transformed to solve for y, what is the name of this new form?

Find the slope of the line passing through a pair of points

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

Explain how the quotient of powers was used to simplify this expression.
