Answer:
4
Step-by-step explanation:
Answer:
Amount invested at 8 % rate = x = $ 15000
Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000
Step-by-step explanation:
Total Amount = $ 34000
Let amount invested at 8 % rate = x
Amount invested at 9 % rate = $ 34000 - x
Total interest = $ 2910
![2910 = \frac{x (8) (1)}{100} + \frac{(34000-x) (9) (1)}{100}](https://tex.z-dn.net/?f=2910%20%3D%20%5Cfrac%7Bx%20%288%29%20%281%29%7D%7B100%7D%20%2B%20%5Cfrac%7B%2834000-x%29%20%289%29%20%281%29%7D%7B100%7D)
291000 = 8 x + 306000 - 9 x
x = 306000 - 291000
x = 15000
So amount invested at 8 % rate = x = $ 15000
Amount invested at 9 % rate = 34000 - x = 34000 - 15000 = $ 19000
The answer is: y = -3/2 x + 8
Graph:
To find the answer we use the formula;
y-y1 = M1 (x - x1)
y-2 = -3/2 (x-4)
When fully solved: the answer is:
y = -3/2 x + 8
3.4, 3 + 0.4, three point four
5.8, 5 + 0.8, five point eight
6.2, 6 + 0.2, six point two
