What is the equation of the circle, with centre (-2,-7) and radius 3 units?

(x + 2)² + (y + 7)² = 9

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 the radius

Here (h, k) = (- 2, - 7) and r = 3, thus

(x - (- 2))² + (y - (- 7))² = 3², that is

(x + 2)² + (y + 7)² = 9

(x+2)^2 + (y+7)^2 = 9

Step-by-step explanation:

The equation of a circle is given by

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

where (h,k) is the center and r is the radius

Substituting into this equation

(x--2)^2 + (y--7)^2 = 3^2

(x+2)^2 + (y+7)^2 = 3^2

(x+2)^2 + (y+7)^2 = 9

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
