A grill at a barbecue restaurant will be used to cook sausage links that are 2 lb each and briskets that are 6 lb each. No more than 120 lb of sausage links and briskets will be cooked on the grill. Which inequality represents all possible combinations of x, the number of sausage links that will be cooked on the grill, and y, the number of briskets that will also be cooked?

6x + 2y < 120

2x + 6y ≤ 120

6x + 2y > 120

2x + 6y ≥ 120

Which system of equations does the graph represent?

y = -x- 4

y = 2x − 2

y = −x + 4

y = 2x − 4

y = x − 4

y = −2x − 2

y = x + 4

y = −2x − 4

A customer at a store paid $64 for 3 large candles and 4 small candles. At the same store, a second customer paid $4 more than the first customer for 1 large candle and 8 small candles. The price of each large candle is the same, and the price of each small candle is the same. Which system of equations can be used to find the price in dollars of each large candle, x, and each small candle, y?

4y = 3x + 64 8

y = x + 68

4y = 3x + 64

8y = x + 60

3x + 4y = 64

x + 8y = 68

3x + 4y = 64

x + 8y = 60
