Acircle has center o(5, −1) and radius 5. which of the following points is on the circle?

v(2, 3)
x(−3, −2)
y(5, −4)
z(6, 9)

The correct answer is the first one listed.

Step-by-step explanation:

First you have to determine what the equation for that circle is.  The standard form of a circle is

where h and k are the coordinates of the center and the radius is squared.  Using the given info, our equation will look like this:

Now we use the coordinates given and plug in 2 for x and 3 for y and do the math and see if the 2 sides are equal.

and 9 + 16 = 25, right?  So that's how you can check the other coordinate pairs to verify that they DON'T work out!

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
