It is 7 regions because you can make a triangle with these lines and there can be one middle region then you would have 6 outside regions. Draw out a triangle but the line intersect on each pointy end. If this is right could I possibly have brainliest? Hope this helped!! :)
Answer:
The distributive property.
Step-by-step explanation:
The distributive property is when you distribute a number to different numbers in a parentheses. For example...
2*x would be 2x, and 2*4 would be 8.
Check the picture below.
notice, we have three pair of sides, let's add them all up to get the area
Dy/dx = (ycos(x))/(1 + y²)
(1 + y²)/y dy = cos(x) dx
(1/y + y) dy = cos(x) dx
Integrating:
ln(y) + y²/2 = sin(x) + c
ln(1) + 1/2 = sin(0) + c
c = 1/2
Thus,
ln(y) + y²/2 = sin(x) + 1/2
