A jar contains only pennies, nickels, dimes, and quarters. There are 29 pennies, 13 dimes, and 21 quarters. The rest of the coins are nickels. There are 91 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
