The Power of a Power Rule. In this case, you basically multiply the two exponents together, and simplify (x^4)^9 to equal x^36
F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8
f^-1(4) = 2(4) - 8
f^-1(4) = 0
Answer: 1/5 with an exponent of 5.
hope this helps :)
Answer:
9625
Step-by-step explanation:
If 385 alcohol swabs were defective, then 385 is 4% of all produced alcohol swabs.
385*25 = 9625
9625 alcohol swabs were produced
