Use the elimination method to solve the system of equations. Choose the correct ordered pair.
12x - y = 25
9x + y = 17
O A. (-2,3)
B. (1, -2)
C. (3,-2)
D. (2, -1)

Convert the cartesian equation (x 2 + y 2)2 = 4(x 2 - y 2) to a polar equation. choices: r4 = -4r2 r2 = 4cos2θ r2 = 4sin2θ

What term makes it inconsistent y=2x - 4 ?

Peter applied to an accounting firm and a consulting firm. he knows that 30% of similarly qualified applicants receive job offers from the accounting firm, while only 20% of similarly qualified applicants receive job offers from the consulting firm. assume that receiving an offer from one firm is independent of receiving an offer from the other. what is the probability that both firms offer peter a job?
