Answer:
y = 4x² -19x -5
Step-by-step explanation:
When you graph it (or use an appropriate tool), it can help us to figure out that the equation is:
y = 4x² -19x -5
(Quadratic regression = the process of determining the equation of a parabola that best fits a set of data)

The answer is b = 3. you subtract 24 from bothe sides and then divide by 2.
Answer:
Step-by-step explanation:
Standard form of a sideways parabola:
Given equation:
Add x to both sides:
--------------------------------------------------------------------------------------------
<u>Standard form of circle equation</u>
(where (a,b) is the center and r is the radius)
Given equation:
Group like terms:
Divide by 2:
Factor by completing the square for each variable:
Rearrange into standard form:
Therefore, the circle has a center at (4.5, 2.5) and a radius of √23
