Rule: Output = 2 * input + 1

Right blank: Output  = - 1

Left blank: Input = 4

Step-by-step explanation:

Rule

Start with the rule

Output = 2 * input + 1

Let the output = y

Let the input = x

y = 2x + 1

Now

Right Blank

x = - 1

y = 2*-1 + 1

y = -2 + 1

y = - 1

That's the output for -2

Left Blank

The second blank asks you to solve for the input (x) The output (y) is 9

9 = 2x + 1                 Subtract 1 from both sides

9-1 = 2x                    Combine

8 = 2x                       Divide by 2

8/2 = 2x/2

x = 4

70,000 + 6,000 + 800 + 30

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,
