What is the value of -3 r + 8 when r = 4?
-12
-4
4
12

To solve we must evaluate the expression. In order to evaluate, all you have to do to solve is replace the r with its value of 4 and multiply it by -3. Then, you must add that product to 8.

Step-by-step explanation:

-3r    + 8

-3(4) + 8

-12   + 8

-4

I hope this helps!

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

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,
