5/50 or 1/10 in winning a prize.
Given:
The parent function is
![f(x)=8x+9](https://tex.z-dn.net/?f=f%28x%29%3D8x%2B9)
To find:
The function after the reflection over the x-axis.
Solution:
We know that, if a function f(x) reflected over x-axis to get the function g(x), then
![g(x)=-f(x)](https://tex.z-dn.net/?f=g%28x%29%3D-f%28x%29)
Putting
, we get
![g(x)=-(8x+9)](https://tex.z-dn.net/?f=g%28x%29%3D-%288x%2B9%29)
![g(x)=-8x-9](https://tex.z-dn.net/?f=g%28x%29%3D-8x-9)
The function after the reflection over the x-axis is
.
Therefore, the correct option is B.
Answer:
-1=p
Step-by-step explanation:
8=8p+13-3p
8-13=8p-3p
-5=5p
-5÷5=5p÷5
-1=p
6.4 months Because 10% of $1,100 is $110
multiply 110 by 6.4 and you get 704
so 6.4 months
