Mathematics

The formula to graph a circle is:
(x-h)^2+(y-v)^2=r^2

Step 1: find the center if the circle.
Using this equation: x^2+y^2=r^2
Step 2: calculate the radius by solving for r
Step 3: plot the radius on the coordinate plane
Step 4: connect the dots to the graph forming a round smooth circle

Step 5: replace your (h,v) with your center points and switch the signs in your equation for the formula of graphing a circle
Step 6: calculate the radius
Step 7: plot the radius points on the coordinate plane
Step 8: connect the dots to the graph of a circle

Im having a hard time on this question and I hope you can help.

The answer would be x ≠ 0

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First start with the left side, doing distributive property

So... -2(x) = -2x and -2(5) = -10 Therefore on the left side you now have -2x -10

Next do the same on the right side

-2(x) = - 2x and -2(-2) = 4 so you have -2x + 4 + 5 and you add 4 and 5, leaving you with -2x + 9

Now that you have simplified both sides the problem now looks like this:

-2x - 10 = -2x + 9

Because you have equal terms on both sides (-2) those cancel out so you have -10 = 9

Just from looking at this we know that the statement is false because -1o does not equal 9

*The symbol, "≠" means not equal to"

Yes the x values are all different, if two were the same then it would not be one but in this case it is

David, Ben, and Jordan shared stickers in a ratio of 8 : 9 : 10. If Ben had 36 stickers, how many stickers did Jordan have?
pantera1 [17]

Answer:

Jordan had 40 stickers.

Step-by-step explanation:

For this ratio, we have David:Ben:Jordan as 8:9:10, and so we need to make it as a more complex fraction, 8/9/10, now we need a multiplier to get us from 9 stickers of Jordan to 36, like a giant one. The common multiplier in this case is 4, and we know that the values must always stay proportional. We multiply everything by 4,and we get a final ratio of 32:36:40, and since Jordan is the last in the ratio David:Ben:Jordan, Jordan ends up with 40 stickers.
