Given the function f(x)=2x-7. What is x when f(x)=17?
Eduardwww [97]

Answer:

x = 12

Step-by-step explanation:

Step 1: Define

f(x) = 2x - 7

f(x) = 17

Step 2: Substitute

17 = 2x - 7

Step 3: Solve for <em>x</em>

<u>Add 7 on both sides:</u> 24 = 2x

<u>Divide both sides by 2:</u> 12 = x

Step 4: Check

f(12) = 2(12) - 7

f(12) = 24 - 7

f(12) = 17

Use this to calculate a 15 percent tip on a $36 bill.


What should I tip on 36 dollars? How much is the tip for $36?

which would be $41.40

What if we split the bill? How to tip? What's the best tip? Use this as a guide for tipping. It can be for anything, such as a restaurant, pizza delivery driver, tour guide, taxi driver, or anything calculating a percentage tip on the total amount.
