How do I find the equation for a parabola

Mathematics
1 answer:
aalyn [17]3 years ago
5 0

Answer:

The easiest way to find the equation of a parabola is by using your knowledge of a special point, called the vertex, which is located on the parabola itself.

Step-by-step explanation:

If you see a quadratic equation in two variables, of the form y = ax2 + bx + c, where a ≠ 0, then congratulations! You've found a parabola. The quadratic equation is sometimes also known as the "standard form" formula of a parabola.

I need help with this geometry
Marysya12 [62]
2x - 3y = 9
- 3y = -2x + 9
y = (-2x + 9)/-3

slope = -2
Since the slope is negative the line passes through quadrants 2 and 4
Therefore the answer is b.

Yet again ACTUALLY ANSWER THE PROBLEM and don't answer if you don't know (you know who you are)
Trava [24]

Answer:

Step-by-step explanation:

Slope is 2

solve into Ax+by=C

Y-y1=m(x-x1)

Y-(-4) = 2(x - (-5))

Y+4=2x+10

Y-2x =6

(0,6)

(-3,0)

Help me please, I’m still struggling with y intercepts, rates of change, etc.
BaLLatris [955]

Answer:

(a) The y-intercepts of both functions are the same, 0.  However, the rate of change for the school library is 0.25, while the rate of change for the city library is 0.35.  

(b) The 3-day late fee at the school library is $0.75 and the 3-day late fee at the city library is $1.05.

Step-by-step explanation:

The functions represented in the question are linear, which means that they have a consistent rate of change over time.  In this example, it means that for every day, the late fee charged by each library is the same.  At the school library, the rate of change is 0.25, which means for each day the book is late, the school charges a fee of $0.25.  At the city library, the table shows that for each day the book is late, the city charges a fee of $0.35.  So, the city library is more expensive.  Y-intercept refers to the initial cost, or how much do the libraries charge if the book is not late, or turned in on time.  In this case, neither library charges a fee for books turned in on time, so both would have a y-intercept of 0.
