First you bring the 9 over with the seven
![-2= \sqrt[3]{x+9}](https://tex.z-dn.net/?f=-2%3D%20%5Csqrt%5B3%5D%7Bx%2B9%7D%20)
Now cube both sides
Finally subtract 9 over and get
Check
![7=9+ \sqrt[3]{-17+9}](https://tex.z-dn.net/?f=7%3D9%2B%20%5Csqrt%5B3%5D%7B-17%2B9%7D%20)
![7=9+ \sqrt[3]{-8}](https://tex.z-dn.net/?f=7%3D9%2B%20%5Csqrt%5B3%5D%7B-8%7D%20)
7=7

Answer:
R + 5b = 300
Step-by-step explanation:
Rogers steps include a scale holding five bricks of equal weight and the scale reads 300 pounds.
We want to write an equation relating Rogers weight and the weight of the bricks to the total weight of the bricks to the total weight shown on the scale.
We have been told to use R for Rogers weight and b for the weight of a single brick.
Since Rogers is holding 5 bricks, the weight of 5 bricks will be 5b.
The sum of Rogers weight and the five bricks is equal to 300 pounds.
Therefore, the equation relating them is:
R + 5b = 300
Answer:
C(g) = 10 + 15g
C'(g) = 80
The monthly charges of Company C for using 2 Gigabyte of data usage.
Step-by-step explanation:
The cell phone plan from Company C costs $10 per month, plus $15 per gigabyte for data used. The plan from Company D costs $80 per month, with unlimited data.
Now, the monthly cost in Company C for using g gigabyte of data will be
C(g) = 10 + 15g ........ (1)
Again, the monthly cost in Company D for using g gigabyte of data will be
C'(g) = 80 ......... (2)
Now, from equation (1), the statement C(2) = 10 + 15 × 2 = 40, means that monthly charges of Company C for using 2 Gigabyte of data usage.
