If the graph of the function g defined by g(x)=x^2+2 is translated vertically downward by 3 units, it becomes the graph of a function h . find the expression for h(x) .

h ( x ) =

What is the length of the unknown leg in the right triangle ?

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.

Use matrices to solve this linear system: 5x1 − 2x2 = −30 2x1 − x2 = −13 x1 = x2 =
