X= -2
look at the 6x-12 you divide -12 by 6 and get x=-2
8/2 = 4
answer: it will take Carlos 4 hours to walk 8 miles
Answer:
Step-by-step explanation:
2012 = 2500
2500 x .50 = 1250
2500 + 1250
2013 = 3750
3750 x .50 =
3750 + 1875
2014 = 5625
5625 x .50 = 2812.5
5625 + 2812.5
2015= 8437.5
8437.5 x .50 = 4218.75
8437.5 + 4218.75
2016= 12656.25
12656.25 x .50 = 6328.125
12656.25 + 6328.125
2017= 18984.375
18984.375 x .50 = 9492.1875
18984.375 + 9492.1875
2018= 28,476.5625
The formula for the average value of a function is
![\frac{1}{b-a} \int\limits^b_a {f(x)} \, dx](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7Bb-a%7D%20%20%5Cint%5Climits%5Eb_a%20%7Bf%28x%29%7D%20%5C%2C%20dx%20)
where b is the upper bound and a is the lower. For us, this formula will be filled in accordingly.
![\frac{1}{2} \int\limits^2_0 {(2x^2+3)} \, dx](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Cint%5Climits%5E2_0%20%7B%282x%5E2%2B3%29%7D%20%5C%2C%20dx%20)
. We will integrate that now:
![\frac{1}{2}[ \frac{2x^3}{3}+3x]](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%5B%20%5Cfrac%7B2x%5E3%7D%7B3%7D%2B3x%5D%20%20)
from 0 to 2. Filling in our upper and lower bounds we have
![\frac{1}{2}[( \frac{2(2^3)}{3}+3(2))-0]](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%5B%28%20%5Cfrac%7B2%282%5E3%29%7D%7B3%7D%2B3%282%29%29-0%5D%20%20)
which simplifies to
![\frac{1}{2}( \frac{16}{3}+6)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%28%20%5Cfrac%7B16%7D%7B3%7D%2B6%29%20%20)
and
![\frac{1}{2}( \frac{16}{3}+ \frac{18}{3})= \frac{1}{2}( \frac{34}{3})](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%28%20%5Cfrac%7B16%7D%7B3%7D%2B%20%5Cfrac%7B18%7D%7B3%7D%29%3D%20%5Cfrac%7B1%7D%7B2%7D%28%20%5Cfrac%7B34%7D%7B3%7D%29%20%20%20%20%20)
which is 17/3 or 5.667
