G(x) = 2x + 1
f(x) = x + 2
B wants you to find g of f of x, or, in other words, g(f(x)).
g(x + 2) = 2(x + 2) + 1
g(x + 2) = 2x + 4 + 1
g(f(x)) = 2x + 5
Depends on what your answering for, for this i’d assume ur answering for the function which the answer would be 3x/x-1 - f(x) = 0. let me know if it’s something else you are trying to solve for
Answer:
66.42°
Step-by-step explanation:
Given
cos ? =
, then
? =
(
) ≈ 66.42° ( to the nearest hundredth )
Let t represent Todd's age now.
.. 4(t -3) -(t -3) = 81 . . . . . . 3 years ago, their differnce in ages was 81.
.. 3t -9 = 81
.. t = (81 +9)/3 = 30
Todd is 30 now.
_____
You can also work this by considering "ratio units." 3 years ago, the ratio of their ages was 4:1, a difference of 3. That difference corresponds to 81 years, so each "ratio unit" represents 81/3 = 27 years. Todd's age then was 1 ratio unit, 27 years. Now, Todd's age is 30.
Answer: Infinitely many
Step-by-step explanation: 2(x-3)=10x-6-8x
2x-6=10x-6-8x
2x-6=2x-6
