(1/4)^-2 - (5^0 x 2) x 1^-1 =
(4/1)^2 - (1 x 2) x 1 = 16-2 = 14
If you raise something to the power of -2, swap numerator and denominator and remove the minus.
So (1/4)^-2 = 4^2 = 16
Also 1^-1 is just 1, not -1.
There are many possible factors:

Hope this helps!!
Answer:
-3
Step-by-step explanation:
-5 = -8 - (- 3)
a) The linear function that models the amount of water after t minutes is given by:

b) It takes 92 minutes to completely fill the pond.
Item a:
- Initially, the pond contains 200 gal of water, that is, the linear function has a y-intercept of 200.
- Filled at a rate of 12 gallons per minute, thus the linear function has a slope of 12.
Then, the function is:

Item b:
It takes t minutes to fill the pond, t is found for which:

Then




It takes 92 minutes to completely fill the pond.
