Algebra: Concepts and Connections EOC Review 2

A teacher is buying T-shirts for her algebra class.

● Long-sleeve T-shirts (x) cost $16 each.

● Short-sleeve T-shirts (y) cost $10 each.

The teacher wants to buy at least 24 T-shirts, and she wants to spend no more than $300 in all. Which system of inequalities represents this situation?

• x + y ≤ 24

  16x + 10y ≥ 300

• x + y < 24

  16x + 10y < 300

• x + y > 24

  16x + 10y > 300

• x + y ≥ 24

  16x + 10y ≤ 300

Exponential function f(x) has a y-intercept of 3 and an x-intercept of -2. The function is always increasing as the value of x increases, but the function never reaches y = 4.

Graph the graph that represents f(x), and move it to the correct location on the coordinate grid. The dashed line can be used to help you answer he question.
