<em>Hopes This Helps</em>
Answer:
Initial amount P = $12000
Interest after 2 years I = 4%*2 = 8%
<u>Investment into Trust fund:</u>
- $12000 + $5000 + 0.08*$12000 = $17960
<u>Interest amount to exceed $20000:</u>
<u>Time required to get $2040:</u>
- 17960*0.045x = 2040
- 808.2x = 2040
- x = 2040/808.2
- x = 2.52 years
The investment will exceed $20000 in the second half of the third year
Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 <u>4x + 14y = - 24</u><u> </u> {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2
Answer: 2x-5y+x+y
3x-4y
Step-by-step explanation: combinded like terms
10x-6y
You have to add the like terms.
