WILL MARK BRAINLIST Use a graphing tool to solve the equation for x. 2^x-4=-4^x+4

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Isabel graphed the following system of equations. 2x – y = 6 y = -3x + 4 she came up with the solution (2,-2). what were the 3 steps she did to get that solution? (make sure they are in the correct order)

If f(x) = 6x – 4, what is f(x) when x = 8? a2 b16 c44 d52
