Sure, Help you with what?
Step-by-step explanation:
Let me know :)
Have an AWESOME Friday <3
1. Move the negative sign to the left.
- ![\frac{19}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19%7D%7B8%7D)
*-50
2. Use this rule: ![\frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D)
![*](https://tex.z-dn.net/?f=%2A)
=![\frac{ac}{bd}](https://tex.z-dn.net/?f=%5Cfrac%7Bac%7D%7Bbd%7D)
-![\frac{19x*-50}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B19x%2A-50%7D%7B8%7D)
3. Simplify - ![\frac{-950x}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B-950x%7D%7B8%7D)
4. Move the negative sign to the left.
-(-950x/8)
5. Simplify 950x/8 to 475x/4
6. Remove parentheses.
Answer:
Length = 10 & width = 3
Step-by-step explanation:
Perimeter = Length + Length + Width + Width
26 = 2Length + 2 Width
26 = 2 ( Length + Width )
13 = Length + width
13 - Length = Width EQUATION 1
Area = Length X Width
30 = Length X ( 13 - Length )
30 = 13Length - Length ^2
Length ^2 - 13Length + 30 = 0
( Length - 3 )( Length - 10 )
Length = 3 or Length = 10
Therefore Length = 10
From equation 1
13 - Length = Width
13 - 10 = width
width = 3
To find the slope of the expression:
![f(x)=y=3x-1](https://tex.z-dn.net/?f=f%28x%29%3Dy%3D3x-1)
We need to remember that this is the Slope-intercept Form of the line equation:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where
m = slope
b is the y-intercept.
Therefore, the slope of the line equation above is m = 3.
