Answer:
c = -3
Step-by-step explanation:
The discriminant is 73, that means we have:
(-1)^2-4*6*c=73
then: 1-24c=73
or -24c= 73 -1
-24c = 72
Then c = 72/-24= -3
The answer is -3

Step-by-step explanation:
Answer:
Money invested in CD account: $2000
Money Invested in Savings Bond: $4000
Step-by-step explanation:
Given
Total amount=$6000
Let
x be the amount invested in CD at 4%
And
6000-x be the remaining amount invested in savings bond at 7%
So mathematically writing
0.04x+0.07(6000-x)=360
0.04x+420-0.07x=360
-0.03x+420=360
-0.03x=360-420
-0.03x= -60
x= -60/(-0.03)
x=$2000
So the amount invested in CD is $2000.
And the amount invested in savings bond is:
=6000-x
=6000-2000
=$4000 ..
