This is a simple rule of third problem
3/4 covers 2/5

Let's say that Bob is x and James is y
x + y = 180
x = 2y
2y + y = 180
y = 60.
James spent 60 dollars.
The answer for the function F(4) = 5/81
<u>Step-by-step explanation</u>:
The given function is F(x) = 5 * (1/3) ^ x
<u>step 1</u> :
The x value is given as the input to get the output from F(x)
<u>step 2</u> :
Here, F(4) means that the x value is x=4
<u>step 3</u> :
Now, substitute x=4 in the given function F(x)
F(4) = 5 (1/3)^4
=5 (1/81)
F(4) = 5/81
Answer:
25 Cards
Step-by-step explanation:
If 5 cards is 20% and you only need 5 more then that means you have the other 80%. So you 20 80/20 which is 4. Then do 4x5=20 then add the 5 you still need.
Hello from MrBillDoesMath!
Answer: Choice D, 3 (x^2+1) + 2
Discussion:
f(g(x)) = f (x^2 + 1) * Note: I think that "x2" was meant to be x^2
= 3 * (x^2 +1) + 2 =
(3 x^2 + 3) + 2
Factor 3 from each term:
= 3 (x^2 _1) + 2
which is choice "d".
Thank you,
MrB
