Answer:
Kitchen - 3.89 quarts or 3 
quarts of latex enamel
Bathroom - 1.12 quarts or 1 
quarts of latex enamel
Step-by-step explanation:
270 feet² for every 3 quartz.
We need how much ft² 1 quart can cover.
So,
270 ÷ 3 = 90 ft²
Every 1 quart covers about 90 ft² of wall.
For kitchen we need to cover 350 ft².
So,
350 ÷ 90 = 3.89 quarts or 3 quarts of latex enamel
For bathroom we need to cover 100 ft².
So,
100 ÷ 90 = 1.12 quarts or 1 quarts of latex enamel
Answer: A or D

<u>To Find Mean:</u><em><u> Add together all numbers and divide by how many they are.</u></em>
Answer:
1). Increases
2). Slope = 4
3). Slope = -1
4). y = 4 when x = 5
Step-by-step explanation:
1). Initially, as x increases, y also increases. (Linear growth has been shown in the graph initially).
2). Afterward, the slope of the graph of the function is equal to 4 for all x between x = 3 and x = 5.
[Slope of the line passing through two points (3, 0) and (5, 4)

3). The slope of the graph is equal to -1 for x between x = 5 and x = 9.
[Slope of the line passing through two points (5, 4) and (9, 0),
Slope = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}

4). The greatest value of y is y = 4, and it occurs when x = 5. (From the given graph)
