To solve the equation -x - 3=.2 - 2x-15, you
could graph of the following system.
y = -x-3
y = 22 - 2x - 15
Use the graph of this system to identify all
solutions of -x-3 = 22 - 2x - 15.

Achemist has 200 ml of a 10% sucrose solution. she adds x ml of a 40% sucrose solution. the percent concentration, y, of the final mixture is given by the rational function: the chemist needs the concentration of the final mixture to be 30%. how many milliliters of the 40% solution should she add to the 10% solution to get this concentration?

One positive number is 9 more than twice another. if their product is 95, find the numbers
