Its the y=3x2one pretty sure
Answer:
The formula for the area of a circle is:
![\pi r^{2}](https://tex.z-dn.net/?f=%5Cpi%20r%5E%7B2%7D)
![\pi =3.14159265359](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14159265359)
1) Multiply pi by the radius squared
The answer would be b. (Which is point)
Answer:
the lines represent absolute value bars
![x=0,10](https://tex.z-dn.net/?f=x%3D0%2C10)
Step-by-step explanation:
STEP 1: Move all terms not containing |5−x| to the right side of the equation.
![3|5-x|=15](https://tex.z-dn.net/?f=3%7C5-x%7C%3D15)
STEP 2: Divide each term by 3 and simplify.
![|5-x|=5](https://tex.z-dn.net/?f=%7C5-x%7C%3D5)
STEP 3: Remove the absolute value term. This creates a ± on the right side of the equation because |x|=±x.
<em>5-x=±5</em>
STEP 4: Set up the positive portion of the ± solution.
![5-x=5](https://tex.z-dn.net/?f=5-x%3D5)
STEP 5: Solve the first equation for x.
![x=0](https://tex.z-dn.net/?f=x%3D0)
STEP 6: Set up the negative portion of the ± solution.
![5-x=-5](https://tex.z-dn.net/?f=5-x%3D-5)
STEP 7: Solve the second equation for x.
![x=10](https://tex.z-dn.net/?f=x%3D10)
NOTE: The solution to the equation includes both the positive and negative portions of the solution.
![x=0,10](https://tex.z-dn.net/?f=x%3D0%2C10)
12, 4, 4/3 has a common ratio.
