How much did each care package weigh?

1. Let the variable be x, which will be the weight of each box.

2. The equation would be total = weight of each box multiplied by the number of boxes and then that gets added to the 7 pounds

52 = 4x + 7

3. 52 = 4x + 7

Subtract 7 from both sides:

45 = 4x

Divide both sides by 4:

X = 45/4

X = 11.25

4. The weight of each care package was 11.25 pounds.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

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,
