Angel has xx nickels and yy dimes. He has a maximum of 22 coins worth a minimum of $1.40 combined. Solve this system of inequalities graphically and determine one possible solution.

For how answer my question this will be the last question can you answer in math subject

Which value of m will create a system of parallel lines with no solution? y = mx - 6 8x - 4y = 12

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.
