Jeff wants to know how many miles it is from his house to school. on a map, the scale is 0.5 inches=2 miles. if his house island school are 3 inches apart on the map, how many miles is it to the school?

It is 12 miles from house to school

Solution:

Given that, Jeff wants to know how many miles it is from his house to school

On a map, the scale is 0.5 inches = 2 miles

His house island school are 3 inches apart on the map

So, from the given scale,

0.5 inches = 2 miles

Distance between school and house in map = 3 inches

Therefore,

0.5 inches = 2 miles

Muliply both sides by 6

Thus, it is 12 miles from house to school

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
