Kayla
Step-by-step explanation:
Vertical lines are always undefined because if your answer has to be divided by zero, the answer is an undefined operation.
Horizontal lines always have the slope of zero!
Answer:
X= -6
Step-by-step explanation:
x-4=2x+2
x-2x=2+4
X = -6
Answer:
g(x)= x+1
Step-by-step explanation:
Given ![f(x)= \sqrt[3]{x+2}](https://tex.z-dn.net/?f=f%28x%29%3D%20%5Csqrt%5B3%5D%7Bx%2B2%7D)
, ![f(x)= \sqrt[3]{x+3}](https://tex.z-dn.net/?f=f%28x%29%3D%20%5Csqrt%5B3%5D%7Bx%2B3%7D)
![f(g(x))= \sqrt[3]{x+3}](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%20%5Csqrt%5B3%5D%7Bx%2B3%7D)
Replace x with g(x)
![f(g(x))= \sqrt[3]{g(x)+2}](https://tex.z-dn.net/?f=f%28g%28x%29%29%3D%20%5Csqrt%5B3%5D%7Bg%28x%29%2B2%7D)
Now we need to find out what we plug in for g(X) to get x+3 under the radical
g(x) +2 is under the radical. we need x+3 , so we replace g(x) with x+`
So g(x)+2 becomes x+1+2 is x+3
Hence g(x) is x+1
The solution is on a graph with parallel lines
Answer: average means add all scores and divide by number of scores earned
last score is x
so the sum is 75+81+x
3 scores so (75+81+x)/3=average
must be no less than (greater than or equal to 80)
(75+81+x)/3≥80
solve
times both sides by 3 to clear fraction
75+81+x≥240
156+x≥240
minus 156 from both sides
x≥84
the studen must earn at least 84 on last exam
