Answer:
Step-by-step explanation:
Take two points from the graph
(0,24) and (6,12)
Find the slope
The formula to calculate the slope between two points is equal to
substitute
---> is negative because is a decreasing function
Find the equation of the line in slope intercept form
we have
Note: The y-intercept is given (0,24)
substitute
We have to multiply 54 * 23, and check where the mistake is.
We start by multiplying 54 by 3, and it gives us 162
Then, we multiply 54 by 20, and it gives us 1080.
Then, we have to add these two results:
The mistake is where 6 is added to 8. It does not give 13, but 14.
The 1 of the 10 goes adding above the 1 in 162.
The result is 1,242.
