Answer:A, B and D
Step-by-step explanation:
A linear relationship is one in which when the variables are plotted, the graph would be a straight line. In a linear relationship, the highest power of the variables is 1. We would compare each of the given relations.
A) Double x and subtract five to get y. This is expressed as
2x - 5. It is a linear relationship.
B) Multiply x and y to get 20. This is expressed as
xy = 20. It is a linear relationship.
C) Multiply x times itself and add five to get y. This is expressed as
x^2 = y. It is not a linear relationship. The highest power of the variables is 2
D)Divide 40 by x to get y. This is expressed as
40/x = y. It is a linear relationship.
Answer:
C
Step-by-step explanation:
This is simple application of the rule of 72.
The rule of 72 determines how long an investment will take to double given fixed interest rate. We divide 72 by annual rate of return and get the estimate of number of years it will take for investment to double.
Thus, here, rate of interest is 5%, so we divide 72/5 and get our rough estimate.
72/5 = 14.4 Years
That's about 14 years, answer choice C
