What is the measure of angle Z

0if x and y vary inversely and y=6 as x=7, what is the constant of variation?

Which linear inequality is represented by the graph?

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.
