Answer:
x=3
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
x^2 + y^2 - 8x + 12y + 40 = 0
x^2 - 8x + y^2 + 12y = -40
Complete the square on the x and y terms:-
(x - 4)^2 - 16 + ( y + 6)^2 - 36 = -40
(x - 4)^2 + (y + 6)^2 = -40 + 16 + 36
(x - 4)^2 + (y + 6)^2 = 12
So the centre is at (4, -6) and the radius is √12.
Answer:
y = 9
Step-by-step explanation:
the equation of a horizontal line parallel to the x-axis is
y = c
where c is the value of the y-coordinate the line passes through
the line passes through (15, 9) and (- 2, 9)
both points have y-coordinate of 9, hence
y = 9 ← is the equation of the line
Answer:
c = 2.9 yards
Step-by-step explanation:
2c = 42.4 - (18.3 x 2)
2c = 42.4 - 36.6
2c = 5.8
c = 5.8 / 2
c = 2.9 yards
