Answer: 11.8
Step-by-step explanation:
F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a
f(x) = (5x+1) / x g(x) = x / (5x+1)
f(1) = 6, but g(6) = 6/31 ≠ 1
So, f(x) and g(x) are NOT inverse functions.
Answer:
h(0) = 7
Step-by-step explanation:
by saying h(0) it is asking you to plug in 0 as the x value
3(0)^2 = 0
0 + 7 = 7
Answer:
He washed 10 cars.
Step-by-step explanation:
To make this easier covert 1/2hours into 1/4 hours. 2 1/2 = 4/2+1/2 = 5/2. Now take 5/2 and make it 1/4th's, 5/2 = 10/4. It takes 1/4 hours to wash one car so, 10/4 divided by 1/4. Don't divide fractions so, 10/4 x 4/1, we switch the second number around to get 40/4. Now we can simplify, 40/4 = 10.
Answer:
4n^3 -10n^2 +16n -10
Step-by-step explanation:
Use the distributive property to eliminate parentheses, then combine like terms.
= 2n(2n^2 -3n +5) -2(2n^2 -3n +5)
= 4n^3 -6n^2 +10n -4n^2 +6n -10
= 4n^3 +n^2(-6-4) +n(10+6) -10
= 4n^3 -10n^2 +16n -10
