Step-by-step explanation:
Key : Plug in the numbers given in the parenthesis into the x values of the corresponding functions.
f(1/2) = 1/ 1/2 - 4 = 1/-7/2 = -2/7
g(1/2) = 1/1/2 - 2 = -3/2
f(-1/4) = 1/-1/4-4 = 1/-17/4 = -4/17
g(-1/4) = 1/-1/4 - 2 = 1/-9/2 = -2/9
To solve this problem, let's use some numbers to help us compare.
Say each tire costs $100.
Deal 1: Buy 3, get 1 free
Total = $300
Ratio = 3:4
---To find the ratio, we'll take the deal price and compare it to the original price ($400)
Deal 2: 1/4 off the total price
1/4 of 400 = 100
400 - 100 = 300
Total = $300
Ratio = 3:4
Therefore, the deals are equivalent.
Correct Answer: D
Hope this helps!
D is the correct answer
x = -2 turns into (x + 2)
x = -1 turns into (x + 1)
x = 3 turns into (x - 3)
We are trying to isolate n, so let's add 806 to both sides of the equation. This gives us:
Our answer is n = 335.
