Answer:
Step-by-step explanation:
The given equation is
We substitute the ordered pairs to see which ones satisfies the equation.
For (-1,-8), we put x=-1 and y=-8 to get:
This is not true.
For we put x=-1 and
to get
This is true
For (3,3/2) we have 2(3)+6(3/2)=15
This implies 6+9=15
15=15
This is also True
For (-5,25/6), we have 2(-5)+6(25/6)=-10+25=15
This is also true.
So ok
reduced by 13% each times 100-13=87 so 87 % of previous
so
t=time elapsed
I=initial amount
C=future amount
C=I(percentrate)^t
so
