Answer:
4(x-3)(x+6)
Step-by-step explanation:
Factor out the 4
4(x2 + 3x - 18)
what 2 numbers add to 3 and multiply to - 18?
-3 and 6
therefore 4x2 + 12x − 72 = 4(x-3)(x+6)
Answer:
Step-by-step explanation:
- Given details help to determine the function only.
- There is no relationship between the mileage and future cost.
- We only consider the current price, decay rate and number of years.
<h3>Car A</h3>
- Cost = 8750
- Year of Manufacturer = 2015
- Decay factor = 12% or 0.12
<u>The function would be:</u>
- f(x) = 8750*(1 - 0.12)^x = 8750*0.88^x, where x is the number of years since year 2015
<h3>Car B</h3>
- Cost = 9995
- Year of Manufacturer = 2017
- Decay factor = 18% or 0.18
<u>The function would be:</u>
- f(x) = 9995*(1 - 0.18)^x = 9995*0.82^x, where x is the number of years since year 2017
Answer:
91
Step-by-step explanation:
25% of 73 = 18.25
18.25 + 73 = 91
actual answer = 91.25
