Answer:
2 hours
Step-by-step explanation:
Y=25x+30
80=25x+30
50=25x
2=x
Answer:
x = 16
Step-by-step explanation:
Alternate exerior angles are congruent when the lines are parallel
So, 8x - 14 = 5x + 34
3x = 48
x = 16
Answer:
![f(a) = \frac{(a+5)}{(a-1)}](https://tex.z-dn.net/?f=f%28a%29%20%3D%20%5Cfrac%7B%28a%2B5%29%7D%7B%28a-1%29%7D)
Step-by-step explanation:
Given : ![f(x) = \frac{(3+x)}{(x-3)}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B%283%2Bx%29%7D%7B%28x-3%29%7D)
In order to find
we will substitute
for
in the given function, that is :
![f(a) = \frac{(3+a+2)}{(a+2-3)}](https://tex.z-dn.net/?f=f%28a%29%20%3D%20%5Cfrac%7B%283%2Ba%2B2%29%7D%7B%28a%2B2-3%29%7D)
![f(a) = \frac{(a+5)}{(a-1)}](https://tex.z-dn.net/?f=f%28a%29%20%3D%20%5Cfrac%7B%28a%2B5%29%7D%7B%28a-1%29%7D)
Hello!
As you can see, the angles we are given make up a 90 degree angle. We have the equation below.
4x=90
To solve we just divide both sides by 4.
90/4=22.5
x=22.5
I hope this helps!
