Angle J and angle M are base angles of isosceles trapezoid JKLM. If angle J= 18x+8 and angle M= 11x+ 15, find angle K

Solving algebraic equations 2m+3=11

Which will form a composite function?

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.
