If the equation (2x + 1) + (3y) + (x + 2y) = 24 represents the perimeter of the triangle, in inches, which represents the equation when solved for x?

• x = 23 - 5y / 3

• x = 25 - 5y / 3

• x = 11 - 5y / 2

• x = 23 - 5y

Consider the equation. -2(30-3x/12) = -5x + 6 What is the solution to the equation?

• There is no solution to the equation.

• There are infinitely many solutions to the equation.

• x = 30 only

• x = 0 only

Answer explanation

The equation simplifies to 5x = 5x, showing that there are infinitely many solutions to the equation.

A cash register used for a student fundraiser contains only one-dollar bills and five-dollar bills. - The cash register has at least $120.00. - Each one-dollar bill is worth $1.00. - Each five-dollar bill is worth $5.00. Which inequality represents all possible combinations of the number of one-dollar bills, x, and the number of five-dollar bills, y, the cash register holds for all positive values of x and y?

• 1.00x + 5.00y ≥ 120.00

• 1.00x + 5.00y > 120.00

• 5.00x + 1.00y ≥ 120.00

• 5.00x + 1.00y > 120.00

Which equation represents the graph?

• y = |2x - 3| + 4

• y = |1/2x + 3| - 4

• y = 2|x - 3| + 4

• y = 2|x + 3| - 4

Answer explanation

The correct equation is y = 2|x + 3| - 4 because it matches the given graph with the absolute value function shifted horizontally by 3 units to the left and vertically shifted down by 4 units.
