When x increases from a to a + 2, y increases by a difference of 8. for which functions is this statement true? a) y = 2(4)^x b) y = 2(8)^x c) y = 4x + 2 d) y = 8x + 2

Anyone? 15m is what percent of 60m; 3m; 30m; 1.5 km?

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.

What is the answer to this problem? ignore the work. what is the correct answer?
