Solve the quadratic by factoring.
x2- 20x + 38= -9x + 8

Which system of linear inequalities 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.

The sum of five and a number n is at least 12
