What expression is equivalent to 1/2 divided by 2/3

What is the solution to the system of equation graphed belowa.(0,-4)b.(2,5),1),-3)

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.

Measure a and b and find their sum. how are the angles related?
