It's a good idea to get into the habit of

using parenthses when substituting

numbers in for variables.

Since x = -4 and y = -2, 5x - y is 5(-4) - (-2).

Now, 5(-4) is -20 and minus a negative 2

can be thought of as plus a positive 2.

So we have (-20) + (+2) which equals -18.

What is the equation of the circle that has a center at (-3, 1) and a radius of 5? A) (x + 3)2 + (y - 1)2 = 5 B) (x - 3)2 + (y +

Gnoma [55]

Answer:

Step-by-step explanation:

The vertex form of the equation of a circle is $(x-h)^2 + (y-k)^2 = r^2$ where (h,k) is the center of the circle and r is the radius. This means that for the circle with center (-3,1) and radius 5 substitute into the vertex form these values. Substitute h = -3, k= 1, and r = 5. The equation becomes $(x--3)^2 + (y-1)^2 = 5^2$ . This simplifies to $(x+3)^2 + (y-1)^2 = 25$ . The solution is C.
