The following set of ordered pairs is an example of direct variation, find the constant ratio between the variables. (hint: find k.) (2, 4) (5, 10) (7, 14) (11, 22) a. k=2 b. k=8 c. k=-2 d. k= 1/2

Thelime contains the point(-3,0) and parallel x-3y=3( show all work)

Someone this asap for a group of students attends a basketball game. * the group buys x hot dogs at the concession stand for $2 each. * the group buys y drinks at the concession stand for $3 each. the group buys 29 items at the concession stand for a total of $70. how many hot dogs did the group buy?

Solve 2x2 + 8 = 0 by graphing the related function. there are two solutions: . there are no real number solutions. there are two solutions: 2 and -2
