Answer:
119.77
Step-by-step explanation:
93.60x.08=7.45 tax
93.60 x .20=18.72 tip
93.60+7.45+18.72=119.77
When it says the "x - 1 " is the factor of that function means when you find the root of the phrase x - 1 which is x = 1 , put it in the function then you have to get zero for the answer :
thus :
![f(1) = 0](https://tex.z-dn.net/?f=f%281%29%20%3D%200)
Thus :
![2 \times {1}^{3} + k(1) - 9 = 0](https://tex.z-dn.net/?f=2%20%5Ctimes%20%20%7B1%7D%5E%7B3%7D%20%20%2B%20k%281%29%20-%209%20%3D%200)
So :
![2 + k - 9 = 0](https://tex.z-dn.net/?f=2%20%2B%20k%20-%209%20%3D%200)
![k - 7 = 0](https://tex.z-dn.net/?f=k%20-%207%20%3D%200)
Add both sides 7
![k - 7 + 7 = 0 + 7](https://tex.z-dn.net/?f=k%20-%207%20%2B%207%20%3D%200%20%2B%207)
![k = 7](https://tex.z-dn.net/?f=k%20%3D%207)
There you go...
Have a great day ❤
