ANSWER
b=1, c=81, and d=9.
EXPLANATION
The given function is:
This function is the same as:
To find the inverse of this function, we interchange x and y.
Solve for y:
Take square root of both sides:
Hence,
b=1, c=81, and d=9.
Answer:
5 months
Step-by-step explanation:
Equate the formulas for the weights of the two boys:
J's weight = 120 lb + (10 lb/mo)m = D's weight = 150 lb + (4 lb/mo)m
Solve as follows: Subtract 120 lb from both sides:
(10 lb/mo)m = 30 lb + (4 lb/mo)m.
Then: (6 lb/mo)m = 30 lb, and m = (30 lb) / (6 lb/mo) = 5 months
Answer: "Fifty-four hundred" .

Answer:
p^2 - 16p - 80
Vieta's formulas
because 4 * (-20) = -80 and 4 + (-20) = -16
p^2 - 16p - 80 = (p + 4)(p - 20)
Answer:
4(x + 1) + 3. question is written wrong.
