An architect was hired to reconstruct a sen that is in the shape of a rectangle. The dimensions of the rectangle are 3 feet by 4 feet. The client wants the dimensions of the den to be doubled. What effect does doubling the length and the width have on the area of the den?

• The new area will be twice the area of the old den

• The new area will be four times the area of the old den

• The new area will be eight times the area of the old den

• The area will be the same

The amount of chlorine, y, needed for a swimming pool varies directly with the amount of water, x, needed to fill the pool. If 21 units of chlorine are needed for every 1.875 gallons of water, which of the following equations describes this relationship?

• 
• 
• 
• 

Determine the equation for the given table

• C = 200t + 1000

• C = 5t + 500

• C = 5t

• C = 200t

Describe the slope as a rate of change. Do they have the same slope? Explain.

• No the slopes are not equal. The slope of QR = 1/2 and the slope of RS = 3/6

• No the slopes are not equal. The slope of QR = 2 and the slope of RS = 6/3

• Yes the slopes are equal. The slope of QR = 1/2 and the slope of RS = 6/3

• Yes the slopes are equal. The slope of QR = 1/2 and the slope of RS = 1/2

The graph below shows the number of kilometers that Jose drove in a certain amount of hours. Describe what the slope represents.

• The slope represents that Jose was traveling at a rate of 40 km/hr

• The slope represents how long Jose's trip took

• The slope represents his distance before he started the trip

• The slope represents that Jose was traveling at a rate of 20 km/hr
