Which best describes the function on the graph?
1 answer:
The right answer is d. inverse variation; k=2
Inverse variation means that when increasing a variable the other decreases at the same rate or vice versa. So, we can write this statement as the following equation:
So, by plotting this equation, the result is shown in the Figure below. As you can see, this graph matches the graph above, so the conclusion is that the function has an inverse variation with k=2

Answer:
The amount invested in the mutual fund that earned 5% was $1,000
The amount invested in the mutual fund that earned 3% was $1,800
Step-by-step explanation:
Let
x ----> the amount invested in the mutual fund that earned 5%
y ----> the amount invested in the mutual fund that earned 3%
we know that
---->
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
Solve for x
<em>Find the value of y</em>
therefore
The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800
