Answer:
Yes, multiplication and division are inverse. yes, for the inverse equation. Yes, addition and subtraction are inverse. yes, for the inverse equation.
Step-by-step explanation:
EXAMPLES.
E.g 21 = 3x division
3x x = 21 inverse
E.g 5+x =8 addition
5=8-x inverse.
Thank you! :)
Answer:
x is undefined
Step-by-step explanation:
2 + 6(x - 4) = 3x - 18 + 3x
Open the bracket
2 + 6x - 24 = 3x - 18 + 3x
collect the like terms
6x -3x - 3x = -18 +24 - 2
0x = 4
x = 4/0
x is undefined
Answer: 
Step-by-step explanation:
Given: Sample size: n = 41
Sample mean 
degrees
Population standard deviation 
degrees
Confidence level (c) = 80% =0.80
Significance level (a) = 1- c = 1-0.80 = 0.20
z-score for 80% confidence level : z = 1.2816 [from z-table]
Confidence level for population mean :-
Hence, 80% confidence interval for the temperatures in the freezer
Answer: A
Step-by-step explanation:
Each value of x maps onto only one value of y.
