What is the y-value in the solution to this system of linear equations?
4x + 5y = -12
2x+3v = -16

Identify the number 127 as a rational or irrational. explain

Describe the symmetry of the figure. identify lines of symmetry, if any. find the angle and the order of any rotational symmetry.

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.
