Answer:
Domain = [5,∞)
Step-by-step explanation:
Given: ![f(x)=-\sqrt{x}](https://tex.z-dn.net/?f=f%28x%29%3D-%5Csqrt%7Bx%7D)
We are given that f(x) is shifted right by 5 units.
Rule : f(x)→f(x-b)
The graph f(x) shifted b units right
So, using rule :
→
So, ![g(x)=-\sqrt{x-5}](https://tex.z-dn.net/?f=g%28x%29%3D-%5Csqrt%7Bx-5%7D)
Now to find domain:
![x-5>0](https://tex.z-dn.net/?f=x-5%3E0)
![x>5](https://tex.z-dn.net/?f=x%3E5)
So, Domain = [5,∞).
Answer: -2 1/3
Step-by-step explanation:
First, change the word into equation
9*x+3=6
Do division first, so 6/9, simplify into 2/3 then subtract it by 3 which is -2 1/3
Answer:
2.28%
Step-by-step explanation:
mean = 5 years = 60 months
standard deviation = 6 months
X = number of years the tires will last
P = probability of ...
z = z-score
6 years = 72 months
z = (# of months - mean) / standard deviation
z = (72 - 60)/6
z = 12/6
z = 2
P(X > 72) = 1 - P(X < 72)
= 1 - P(z < 2)
(using a Standard Normal Probabilities Table we can see that P(z < 2) = .9772)
So:
= 1 - .9772
= 0.0228 OR 2.28%
You can factor out a 2 from all. Idk if that helps but here ya go. 10x+3x-4
