An equation of direct variation is something like
If we have a value for x and y, we simply have to plug these values and see which constant k suits our case:
So, the relation
is a relation of direct variation and it includes the point (-10,-17).
Answer: x equals 2
Step-by-step explanation:
try it put 2 its 2
Since all of these numbers have the same variable they can all be added up to get a sum of 10a which is its simplified form.
4+2x+35 = 39+2x
39+2x = x+27
12+2x = x
12 = -x
x = -12
Thus, TR equals -12+27 which is 15. TR=15
Future value 1000 a year from now. We are expected to pay about 6% less today to get the future value.
So the answer should be around $940, which makes an easy choice.
However, to make sure, we use the compound interest formula:
F=P(1+i)^n
where i=6%/12=0.005 [monthly interest]
n=1year * 12 months / year = 12 months
1000=P(1.005)^12
=>
P=1000/1.005^12=$941.91 is what needs to be deposited today.
