Hello :
the line has an undefined slope if paralel a axis- y : equation x = 1 (<span>passes through the point (1, 3))</span>
8 - 4(-x + 5)
As you already know, in order to find the equivalent expression to our already given one, we have to simplify it first :)
8 +4x - 20
**Remember that a negative times a negative is always a positive!!**
Add like terms.
4x + (8 - 20)
Simplify.
4x + (-12)
Get rid of parenthesis.
4x - 12
Look at our answer choices.
Our answer is a. 4x - 12
~Hope I helped!~
Your answer is 7^(- 2) or
![\frac{1}{ 7^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%207%5E%7B2%7D%20%7D%20)
or
Answer:
92 m
Step-by-step explanation:
Use the Pythagorean theorem to find the length of the shorter side.
Let w = length of the shorter side.
![w^{2} + 30^{2} = 34^{2} \\ w^{2} + 900 = 1156\\w^{2} = 256\\w = \sqrt{256} = 16](https://tex.z-dn.net/?f=w%5E%7B2%7D%20%20%2B%2030%5E%7B2%7D%20%20%3D%20%2034%5E%7B2%7D%20%5C%5C%20w%5E%7B2%7D%20%20%2B%20900%20%3D%201156%5C%5Cw%5E%7B2%7D%20%20%3D%20%20256%5C%5Cw%20%3D%20%5Csqrt%7B256%7D%20%3D%2016)
The perimeter is 2l + 2w = 2(30) + 2(16) = 60 + 32 = 92 m
As x approaches 3 from the right, the limit is 3. There is a closed hole up there AT x=3 y=7, but we don't care about what happens AT x=3, only what happens as x APPROACHES 3.
