General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Distance Formula:
![d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
- Midpoint Formula:
![(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%29)
Step-by-step explanation:
<u>Step 1: Define</u>
(5, -1)
(-9, -1)
<u>Step 2: Find distance </u><em><u>d</u></em>
- Substitute:
![d = \sqrt{(-9-5)^2+(-1-(-1))^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-9-5%29%5E2%2B%28-1-%28-1%29%29%5E2%7D)
- Simplify:
![d = \sqrt{(-9-5)^2+(-1+1)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-9-5%29%5E2%2B%28-1%2B1%29%5E2%7D)
- Subtract/Add:
![d = \sqrt{(-14)^2+(0)^2}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B%28-14%29%5E2%2B%280%29%5E2%7D)
- Evaluate:
![d = \sqrt{196}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%7B196%7D)
- Evaluate:
![d = \14](https://tex.z-dn.net/?f=d%20%3D%20%5C14)
<u>Step 3: Find Midpoint</u>
- Substitute:
![(\frac{5-9}{2},\frac{-1-1}{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7B5-9%7D%7B2%7D%2C%5Cfrac%7B-1-1%7D%7B2%7D%29)

Answer:
29.134
Step-by-step explanation:
You take 20% from 145.67 and that's what you get.
<span>1 12 f(x) = g(x)
or 112*(</span>14x3 + 28x2 – 46x )= <span>2x + 7
and </span>112*(42 +56 – 46x )= <span>2x + 7
</span>112*(98 – 46x )= <span>2x + 7
</span>and 10.976- 5.152x=2x+7
and -5.152x-2x=7-10.976
we have -5.154x= -10.969
and x= 10.969/5154
