Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form use the method of completing the square
Given
x² - 8x + y² - 2y - 8 = 0 ( add 8 to both sides )
x² - 8x + y² - 2y = 8
add ( half the coefficient of the x/y terms )² to both sides
x² + 2(- 4)x + 16 + y² + 2(- 1)y + 1 = 8 + 16 + 1
(x - 4)² + (y - 1)² = 25 → B
Answer:
No solution.
Step-by-step explanation:
y + 3x - 4y = 0 + 0.75x
- 3y + 3x = 0 + 0.75x
- 3y + 3x - 0.75x = 0 + 0.75x - 0.75x
- 3y + 2.25x = 0
Answer:
x=48
Step-by-step explanation:
(x+34)+(2x+2)=180
The measure of that angle is 60 degrees. To solve this, first, you set the 2 measures equal to each other, because they are congruent. So your equation is 6x=5x+10. Subtract 5x from both sides, leaving you with x=10. Lastly, substitute 10 for x. You multiply 6 by 10, which equals 60.
