4(x+15) = 640

4(x) + 4(15) = 640

4x + 60 = 640

4x = 640 - 60

4x =580

x = 580÷4

x = 145

What is the equation of the circle with center (1,1) that passes through the point (-3,4)?
MakcuM [25]

Answer:

(x - 1)2 + (y - 1)² = 5²

Step-by-step explanation:

Adapt the standard equation of a circle with center at (h, k) and radius r:

(x - 1)^2 + (y - 1)^2 = r^2

Here one point on the circle is (-3, 4), and so the radius is √[(-3)² + 4² ] = 5

Thus, the desired equation is:

(x - 1)^2 + (y - 1)^2 = 5^2      or     (x - 1)2 + (y - 1)² = 5²
