Px + qy = r
2px - qy = 2r
when solving this system of equations, x =

What is always true about a positive integer raised to a negative odd power?

Varies inversely with x. if y=8.5 when x=-1 find x when y=-1

The input to the function is x and the output is y. write the function such that x can be a vector (use element-by-element operations). a) use the function to calculate y(-1.5) and y(5). b) use the function to make a plot of the function y(x) for -2 ≤ x ≤ 6.
