Answer:
Step-by-step explanation:
(x-6)² + y²-8y = 0
Put the equation into center-radius form.
complete the square
coefficient of the y term: -8
divide it in half: -4
square it: (-4)² = 4²
add 4² to both sides to complete the square and keep the equation balanced:
(x-6)² + (y²-8y+4²) = 4²
(x-6)² + ( y-4)² = 4²
center (6,4)
radius 4
Answer: James did not received 60 votes.
Step-by-step explanation:
Given: In a school election,
Percentage of votes received by James = 75%
Percentage of voted hadn't received by James = 100% - 75% = 25%
If 240 students voted , the number of votes hadn't received by James= 25% of 240

Hence, James did not received 60 votes.
Answer:
x = 11
Step-by-step explanation:
Substitute y = -1 into the equation.
x+2y = 9
; x+2(-1) = 9
x+(-2) = 9
x-2 = 9
x = 9+2
x = 11
