Use the substitution method to solve the system of equations

3x+2y=13

y=x-1

The perimeter of a movie screen is 54 meters. the screen is 18 meters wide. how tall is it?

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.

Perform the indicated operation. y^2 + 3y - 10 / 3y + 15
