Kara bought a dvd for $22 and a cd for less than the cost of the dvd. let c represent the cost of the cd. write an inequality to show the cost of the cd.

Factor x2 – 8x + 15. which pair of numbers has a product of ac and a sum of what is the factored form of the

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
