1 real solution means that it has a multiplicity aka
if r is the solution
0=(x-r)^m
theone that fits that is B, the solution is x=3
B is answer
Answer:
-9
hope it helped and stay safe
Okay so say that x=amount invested with 6% and y=amount invested with 9%
x+y=8,500 so > x=8500-y
6%=0.06 <span>9%=0.09</span>
0.06x +0.09y=667.5 (Substitute in x=8500-y so only numbers and y)
0.06(8500-y)+0.09y=667.5 (expand brackets)
510-0.06y+0.09y=667.5 (-510)
0.03y=117.5 (/0.03)
$3916.67=Y ->9%
X=8500-Y
x=$4583.33 ->6%
The answer is Compound Quarterly
