Answer:
C. 10
Step-by-step explanation:
We are given a graph representing the height of the elevator with respect to time.
Since, we know that,
X-axis represents the 'time' in seconds and y-axis represents the 'height of the elevator' in feet.
As, the coordinate points on the graph are given by,
(1,10), (2,20), (3,30) and (4,40).
So, the rate of change can be found out by solving,
.
Hence, the rate of change of the relationship is 10.
Answer:
10%
Step-by-step explanation:
To find the percent increase in the price of the insurance policy, we first need to take the total value of the original price of the insurance policy and subtract it to the new price of the insurance policy.
Price increase = New Price - Original Price
New Price = $2,200
Original Price = $2,000
Price Increase = 2,200 - 2,000
Price Increase = 200
Now to find the percentage increase, we take the price increase and divide it by the original price and multiply it by 100.
Total increase % = 
Total increase % = 
Total increase % = 
Answer:
9
Step-by-step explanation:
because 9 is in front of the variable y
whenever there is a number before a variable then that number is a coefficient
For example:
3x+2x+5x=y
3,2,5 are all coefficients of x
