Answer:
$1680
Step-by-step explanation:
Principal loan amount x Interest rate x Time
= 12000 × 14% × 1
=12000 × 14/100 × 1
=168000/100 × 1
=1680
Answer:
- A. Since 11 ≠ 9, there is no solution
Step-by-step explanation:
<u>Given system:</u>
- 1.75x + 1.25y = 2.75
- 7x + 5y = 9
<u>Multiply the first equation by 4:</u>
- 4(1.75)x + 4(1.25)y = 4(2.75)
- 7x + 5y = 11
We get same equation as the second one with the difference that the right side equals to 11.
Since left sides are same and right sides are different, the system has no solution.
Correct choice is A
It should be written in the form ax²+bx+c=0,
so you meed to move -8 to the left side
2x²+6x+8=0
the number in front of x² is a
the number in front of x is b
the number without x is c,
so a=2, b=6,c=8
