Step-by-step explanation:
Any value of n makes this equation true.
Answer:
(-7, 4) and 7
Step-by-step explanation:
The standard equation of a circle is expressed as (x - a)^2 + (y - b )^2 = r^2
Where the center is the point (a, b) and the radius is r
Note: simply inserting the variables and playing around with your signs gives you the value for (a and b)
The square root of the radius gives you the value for r
Answer: x=-y-30/10
1) subtract 30 from both sides
y−30=−10x
2) divide both sides by -10
-y-30/10=x
3) switch sides
x=-y-30/10
