9y is the answer I believe
The radical function is 3√x + 1.
Since the cubic root of zero is zero, 0 would be x.
Add zero and one, which gives you 1. 1 is y.
You get (0,1)
Since this is a positive radical, it would be going to the top right.
So, the domain is x ≥ 0
the range is y ≥ 1
Harrison is correct because the 305 in the actual problem is greater than the 300 in the estimate and 57872 is less than 60000. Harrison arrived at his prediction by rounding to the nearest ten thousand and nearest hundred.
Since there are 2 variables there will be 2 answers.
Answer: Marked price Rs. 600
Step-by-step explanation:
Let M be the marked price
1) When shop keeper sold at 20% discount, ie. SP = 0.8M
CP - SP = 20
CP = 20 + SP
CP = 20 + 0.8M
2) When shopkeeper sells at 8% discount, he makes a profit of 10%
SP = 0.9M/1.08
Equating 1 and 2, we get
20 + 0.8M = 0.9M/1.08
21.6 + 0.864M = 0.9M
0.036 M = 21.6
M = 21.6 / 0 036
M = 600
