Answer: 4
Step by step explanation
-9-f-7=-7f+8
7f-f=9+8+7
6f=24
f=24/6
f=4
Answer:
1/2
Step-by-step explanation:
5/10 houses gave her chocolate
if you simplify 5/10 by dividing by both the top and bottom by 5 to get 1/2
Reflection across the line y= x, cause to interchange the x and y coordinate
p(x,y) ⇒ p(y,x)
For this case we have the following difference equation:

Applying separable variables we have:

Integrating both sides we have:

applying exponential to both sides:

For y (1) = 1 we have:

Thus, the particular solution is:

Whose domain is all real.
Answer: y = 0.2 * exp ((3/2) x ^ 2) Domain: all real numbers
