Solve for x. 7x−9< 12 or 14x+8> 11

Given: m zade = 60° and m2cdf = (3x + 15) prove: x = 15

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

Which statement describes the slope of the line?
