The first one is infinite many solutions
The second one is (x=0) one solution
The third one is (x=3) one solution
The fourth one is no solution
The last one is no solution
Answer:
Step-by-step explanation:
let be a constant written as:
It is given that y=4, x=-40
#We substitute x, y values in our function:
We substitute the constant value in the equation:
Replace x^2+y^2 with r^2. Also replace y with r*sin theta.
Then we have r^2 = r*sin theta.
this can be reduced to r = sin theta.
