A)The y-intercept is 50 because when X=0, y=50. This shows that the car was moving at 50 mph as an initial speed.
B) in two hours (from 1 to 3) the speed increased by 4 miles per 2hours. (from 52 to 56). 4/2 = 2 mph, which is the average rate of change. This represents the amount of speed increased each hour.
C) y=2x+50, and y=60 in this case, so 60=2x+50
60=2x+50
-50 -50
-----------------
10=2x
5=x, so the domain is X<=5 (less than or equal to 5)
Answer:5
Step-by-step explanation:
Because
Remark
You can get it just by looking at the net. It has 6 squares. Each square has a side of 5 cm by 5cm. Find the area of 1 square and multiply by 6.
Step One
Find the area of one square.
<u>Formula</u>
Area = s^2
<u>Solve</u>
Area for 1 square = s^2 = 5^2 = 25 cm^2
Step Two
Find the area for six squares.
Area of the net = 6*Area of one square = 6 * s^2
6*s^2 = 6 * 25
Area = 150 cm^2
Answer:
The first one the slope is 0.
The second one the slope is 1/2
Answer:
B) is the correct answer because the 5 shirts are supposed to be LESS THAN 55, hence the less than symbol.
