Answer:
See below.
Step-by-step explanation:
So we have the two functions:
![f(x)=5x+4\text{ and } g(x)=-2x+1](https://tex.z-dn.net/?f=f%28x%29%3D5x%2B4%5Ctext%7B%20and%20%7D%20g%28x%29%3D-2x%2B1)
1)
First, find the values of each function:
![f(x)=5x+4\\f(6)=5(6)+4\\f(6)=30+4=34](https://tex.z-dn.net/?f=f%28x%29%3D5x%2B4%5C%5Cf%286%29%3D5%286%29%2B4%5C%5Cf%286%29%3D30%2B4%3D34)
![g(x)=-2x+1\\g(-8)=-2(-8)+1\\g(-8)=16+1=17](https://tex.z-dn.net/?f=g%28x%29%3D-2x%2B1%5C%5Cg%28-8%29%3D-2%28-8%29%2B1%5C%5Cg%28-8%29%3D16%2B1%3D17)
Therefore:
![f(6)+g(-8)\\=(34)+(17)=51](https://tex.z-dn.net/?f=f%286%29%2Bg%28-8%29%5C%5C%3D%2834%29%2B%2817%29%3D51)
2)
Plug in the number into the function:
![g(x)=-2x+1\\g(4)=-2(4)+1=-8+1=-7](https://tex.z-dn.net/?f=g%28x%29%3D-2x%2B1%5C%5Cg%284%29%3D-2%284%29%2B1%3D-8%2B1%3D-7)
3)
Like the last one:
![f(x)=5x+4\\f(-2)=5(-2)+4=-10+4=-6](https://tex.z-dn.net/?f=f%28x%29%3D5x%2B4%5C%5Cf%28-2%29%3D5%28-2%29%2B4%3D-10%2B4%3D-6)

Answer:
x = ab/c
Step-by-step explanation:
The applicable theorem tells you the product of chord lengths is the same for the two crossing chords:
ab = cx
x = ab/c . . . . . divide by the coefficient of x
Answer:
6/25
Step-by-step explanation:
To find the probability of a compound event using data recorded from an experiment. Then, find the number of occurrences of the compound event. The experimental probability is the ratio of the number of occurrences to the total number of trials.
You use the 20% coupon first because it's a percentage of the total amount. You don't want to lower the total amount before using it.
20% of 40$ is 8$ off
20% of 35$ is 7$ off
use the 20% then the -5$
