<h3>
Answer: B) 15 mph</h3>
====================================================
Explanation:
The equation d = 65t means that the rate is r = 65. So Malcolm's family travels at an average rate of 65 mph. Note this is the slope of the line.
The graph has a slope of 50 because each time we go up 50, we move to the right 1. Ie, slope = rise/run = 50/1 = 50. You could use the slope formula to get the same result.
Since the graph has a slope of 50, this means Theo's family is going at an average speed of 50 mph.
Subtract the two speeds to get 65-50 = 15 mph

but where is the question please type your full questions
The average is determined by summing up the data sets accumulated and then divided by the number of data points. In this case, we sum up all of the balances in a day in one month- that is for 30 days and divide the total by 30. This is the average daily balance.
radical -2 = √2i
radical -18 = √18i = 3√2i
So their sum = 3√2i + √2i
= 4√2i answer
