f(-10) = 4
f(-2) = 4
Since y is constant while x isnt we just dont need to put x
f(x) = 4
Answer:
x² + 2x + y² + 4y = 20
(x² + 2x + 1) - 1 + (y² + 4y + 4) - 4 = 20
(x + 2)² + (y + 4)² - 5 = 20
(x + 2)² + (y + 4)² = 25
Therefore, the center is (-2, -4) and the radius is √25 = 5.
Answer:
I= 84
Step-by-step explanation:
for
since D is the rectangle such that 0<x<3 , 0<y<3
The answer is 8y+6
To simplify
we multiply 4y by 2 and we get 8y
multiply 3 by 2 and get 6
