Switch the y and x then solve for y, so I believe b.
Answer:
d. c = 100; (x – 10)²
Step-by-step explanation:
Note that (x+a)²=x²+2ax+a².
In our case, 2a=-20, so 'a' must be -10.
Since c=a², and a=-10, c=(-10²)=100.
Since a=-10, the perfect square is (x – 10)²
The marching l meaning of the X intercept is when the school receives $0
3x^-2 can be written
3/x^2 because x^-2 is = 1/x^2
