Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.
<u>4h + 7 = 4h - 3</u>
Subtract 4h from each side: 7 = -3
There is no value of ' h ' that can make this a true statement,
so the equation has no solution.
Answer:
7/2, 3.5 (depending on which form you want it in)
Step-by-step explanation:
Looking at the numbers on the side, lets take two points they already gave us.
It goes up 14, and over 4 from 0,0.
14/4 Simplify.
7/2
7/2 is your slope
Note:
For those asking why it isn't "10/3" or anything else, It's because we can't be sure the line crosses that coordinate at that point. So lets just take two points where we know the actual coordinates, and derive the slope from that because it's more accurate.
