7x - xy = -18 x = -4
First, fill the -4 in where the "x's" are.
7<u>(-4)</u> - <u>(-4)</u>y = -18
Then, add the 28 over.
-28 + 4y = -18
<u>+28</u> <u>+28
</u>4y = 10
Then, get the variable by itself, so you would divide the 4 over.
4y = 10
<u>÷4</u> <u>÷4
</u>
<em><u>y = 2.5</u></em>
Answer:
There is nothing positive or negative about zero. Zero is just zero. It is NEITHER positive NOR negative. To the right of zero on number line are positive numbers and on the left of zero, lie the negative numbers on the number line.
Using the future value annuity to solve the question we proceed as follows:
FV of annuity=P{[(1+r)^n-1]/r}
P=periodic Payment
r=rate per period
n=number of periods
from the question:'
P=$3,800
r=8.5%
n=5 years
hence:
A=3800{[(1+0.085)^5-1]/0.085}
A=$22,516.42
10+ 10 = 20j
20j- 9= 11
The answer is 11 or if in the quiz it is 11j
