Answer:
5 mph
Step-by-step explanation:
c+15+c=2c+15 mph going down stream.
2.4(2c+15)=60
4.8c+36=60
4.8c=24
reflection of
over the y axis we get 
Step-by-step explanation:
We need to find the reflection of f(x)=sqrt x over the y axis
So, reflection over y- axis
If the function f(x) is transformed over y-axis then the new function g(x) will be 
So, finding reflection of
over the y axis we get:

So, reflection of
over the y axis we get

We have that in this case the following equalities are met:
DH = HF
x + 3 = 3y
GH = HE
3x - 3 = 5y + 4
We then have the following system of equations:
x-3y = -3
3x-5y = 7
Resolving the system graphically we obtain the following values:
x = 9
y = 4
Note: see attached image.
Answer:
The values of x and y are:
x = 9, y = 4
To simplify this all you need to do is distribute the 4x across each term in the parenthesis
