For it to be non-linear, the rate of change cannot be constant. For the first table the rate is a constant 1 and the second table has a constant rate of -1. The 3rd and 4th tables have no constant rate and thus are non-linear.
The 4th table is increasing while the 3rd table is decreasing.
So the 3rd table, Set C, is the only non-linear negative association between x and y.
Answer x=-4
This would make a straight line going perpendicular to y=-3 and would pass through the point -4,3.
Answer:
D. 16.7%
Step-by-step explanation:
Rate of return is:
R = (Vf - Vi) / Vi
R is the rate of return, Vf is the final value, and Vi is the initial value. Essentially, you're finding the change in value and dividing by the initial value.
R = (1750 - 1500) / 1500 = 0.167 = 16.7%
Make sure that you divide by the initial value, not the final. If you divided by 1750 instead, you would have gotten 14.3% which is not correct.
Make sure you check your sign as well. The value increased, so the rate of return is positive.
A-b = 0 is only fulfilled if a=b, then ab = a^2 = b^2
