Two divers are underwater. One diver is at a depth of 32 meters, while the other diver is at a different depth. The given equation can be used to find the possible depths, x, in meters, of the other diver. |x-32| = 11 Enter values to complete the sentence about the other diver’s depth, in meters. The other diver is at a depth of either

|2x| = 8 What are the two solutions?

An inequality is shown:

-3x + 7 ≥ -x - 5.

What is the solution set for x?

• {x | x ≤ 6}

• {x | x ≥ 6}

• {x | x ≤ -6}

• {x | x ≥ -6}

Cardiac output, D, is the amount of blood that the heart pumps per minute. The value of D can be found using the formula shown, where V is the amount of blood that the heart pumps with each heartbeat and R is the number of heartbeats per minute. D = V · R. Complete the equation to represent V in terms of D and R.

Janelle buys blackberries and raspberries to make pies.

Blackberries cost $8 per pound.

Raspberries cost $9 per pound.

Janelle can spend a maximum of $40.

Create and inequality to represent how many pounds of blackberries, b, and raspberries, r, Janelle can buy.

• 8b + 9r = 40

• 8b - 9r = 40
