x 2 + y 2 + a x + b y = c
x2 + y2 − 2x + 6y − 6 = 0
Steps:
x^2 + y^2 - 2x + 6y - 6 = 0
(x - 1)^2 + (y - (-3)^2=4^2
Which means...
Center = (1,-3)
Radius = 4
Or option B
Answer:
<em>X</em> = 27 13/30
Step-by-step explanation:
First you need to find the least common denominator of 5 and 6 to get 30 so it is 25 5/30 + 7 12/30 + <em>x</em> = 60. From there you add the two together to get 32 17/30 + <em>x</em> = 60. Subtract 32 17/30 from both sides of the equation to get the value of <em>x</em> which comes out to 27 13/30.

Add 720 degrees (which represents two full revolutions around the center) to -800. Result: -80 degrees. This angle is in Quadrant IV.
Subtracting 80 from 360 will give you a positive angle co-terminal with -800 deg. 360 - 80 = ?
Answer:
x = 10
Step-by-step explanation:
To isolate the variable (x) you would first write out x - 3 = 7. Now to make x on its own we have to get rid of the -3 so to do that we would add the reciprocal of -3 (or the opposite) which is +3. x - 3 + 3 = 7 + 3 or x = 10.
