Standard form is ax+by=c
mnus 7y both sides
6x-7y=0
It is prime, it can't be divided by anything, but itself and one.
-4 is also a geometric mean
if we consider a(first element in series)=1 and r(common ratio)=-4 then the series would be
1,-4,16,-64,256,…..,a(-4)^(n-1 )
where n is nth term
from this -4 would be the geometric mean if we consider -4 as common ratio .
If we consider 4 as common ratio then geometric mean should be 4
so you should mention whether common ratio >0 or not (r>0 or not) .
[without ‘r’ value you can’t solve the question but in general most of the teachers will consider r>0.]
So, -4 won’t be geometric mean of 1 & 16
Answer:
based on the equation he would make $2.5 in the first month but realistically he would earn around $30 in the first month
Step-by-step explanation:
2000+2000(.015)(1/12)=2002.5
2002.5-2000=2.5
3y - y + 8 - 2 = 20
3y - y = 2y
8 - 2 = 6
2y + 6 = 20
2y = 20 - 6
y = 10 - 3
the answer is: y = 7
