Please help! Billy just received $10 for his birthday and immediately spent $2.50 on a pack of baseball cards. He then wants to
buy some boxes of candy that cost $1.50 each.
If Billy has $7.50 remaining, which of the following equations will give you the number of boxes, x, that Billy could buy?

Answer:
Center: ( -1 , 2 )
Radius: 6
Step-by-step explanation:
The equation for a circle is given as follow:
Where,
the Center is: ( h , k ) (note that the signs of the number are different)
and the radius is: r
So if we compare the original circle equation to the equation in the question we can see that:
the Center is: (-1,2)
and the radius is: = 6
2. To draw the graph find points that lay on the circle, it's better to take the values of x and y from the Center:
first sub y=2 in the equation to find the values for x:
AND
AND
- The points are A(5,2) and B(-7,2)
second sub x= -1 in the equation to find the values for y:
AND
AND
- The points are D(-1,8) and E(-1,-4)
After finding the points write them in the graph and match them together to get the like the circle in the picture below:
Answer:
D. - 1/6
Step-by-step explanation:
M + 2/3 = 1/2
M = 1/2 - 2/3
We know that and this is the only point when sin and cos are equal lengths. Because both
Now if the sin of 30° is a half that would mean that cos of 60° is also a half.
Hope this helps.
