1.) For the following system, use the second equation to make a substitution for x in the first equation. 3x + 2y = 7x - y + 3 = 0 What is the resulting equation? a. 3x - y - 3 + 2y = 7b. 3(y - 3) + 2y = 7c. 3y - 3 + 2y = 72.) Which of the following would not be the result of a substitution in the following system?2x + y = 7y - x = 1a. 7 - 2x - x = 1b. 2x + x + 1 = 7c. 2(y + 1) + y = 73.)Solve the following system of equations by the substitution method. 8x = 2y + 53x = y + 7What is the solution set?a. {(-41/2, -9/2)}b. {(-9/2, -41/2)}c. ∅

The hourly wage increase each employee receives each year depends on their number of years of service. Every three years of service means an increase of $0.50 per hour. So, employees that have been with the company for less than three years can expect to receive an increase of $0.50 per hour. Employees that have been with the company for at least three years, but less than six years can expect an increase of $1.00. Employees that have been with the company for at six years, but less than nine years, receive an increase of $1.50 per hour. And, employees of at least nine years, but less than twelve years receive an increase of $2.00. Write a function to represent this scenario.Which graph represents this wage increase for x < 12?
