Answer:
y=1/2x+1/2
Step-by-step explanation:
In order to find the slope, you can use rise/run, in this case, the slope is 1/2 and the y-intercept is at (0, 0.5)
Let's assume
number of nickels =n
number of dimes =d
we are given
total number of coins =9
so, we get
we know that
1 nickel =$ 0.05
and
1 dimes =$0.10
so, total amount is
we are given
total amount =$2.15
so, we get
so, we get system of equations as
................Answer
1. Find dy/dx for the given family: dy/dx = ce^x
2. Take the negative reciprocal of this result: (-1/c)e^x
3. Integrate this last result with respect to x: (-1/c)e^x
This last result is the desired orth traj of the family of curves y = ce^x.
