Answer:

  A)  -15

Step-by-step explanation:

The average rate of change of f(x) on interval [a, b] is given by ...

  (f(b) -f(a))/(b -a)

Here, you have ...

  f(x) = -2^x +70

  [a, b] = [2, 6]

so the average rate of change is ...

  (f(6) -f(2))/(6 -2) = ((-2^6 +70) -(-2^2 +70))/4 = (-64 +4)/4 = -16+1

  average rate of change = -15

Inverse Functions (please help)

Answer:

The procedure for this case is add three, then divide by 5.

Step-by-step explanation:

if y=5x-3

to find the inverse, we exchange x and y then solve for the new y.

x=5y-3   add 3

x+3 = 5y   divide by 5

(x+3)/5 = y

or

inverse, y=(x+3)/5

The procedure for this case is add three, then divide by 5.

melamori03 [73]
2nd attempt carries a price of 6% extra, so (6/100) * 548 is 32.88, so 548 + 32.88, the price is 580.88.

for the 3rd attempt 6% extra of that, (6/100) * 580.88, is 34.8528, so the price is 615.7328.

4th attempt is 6% extra of that, (6/100) * 615.7328, 36.943968, adding that will give us 652.676768.

The photo is kinda blurry but I need help fast
enyata [817]

To find the rate of change find the difference in the Y values for every X value.

From X 1 to X 3 the Y value changes by -10

-10 / 2 = -5.

The rate of change is -5.

The initial value is when X = 0

When X is 1, the Y value is 20, using the rate of change of -5, this means when X is 0, the Y value would be 25.

The answer would be, the initial value is 25, rate of change is -5
