What is the radius of a circle whose equation is x2 + (y – 8)2 = 25?

5

25

50

625

r = 5

Step-by-step explanation:

Compare this equation to the standard form

(x - h)^2 + (y - k)^2 = r^2

Through this comparison we see that h = 0, k = 8 and r = 5.

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
