A parabola can be represented by the equation y2 = 12x. which equation represents the directrix?
Gelneren [198K]

The equation of the directrix is x = -3

<h3>What is Parabola?</h3>

A mirror-symmetrical, roughly U-shaped plane curve known as a parabola. It corresponds to a number of mathematical models that appear to be superficially dissimilar but yet all define the exact same curves. A point and a line are one way to describe a parabola.

<h3>According to the given information: </h3>

Given the general equation of a parabola expressed as

(y-y0)² = 4a(x-x0) ... 1

Equation of the directrix will be expressed as x = x0 - a

From the equation given;

y² = 12x ... 2

Comparing 1 and 2;

x - x0 = x

-x0 = x - x

-x0 = 0

x0 = 0

Similarly;

y-y0 = y

-y0 = y - y

-y0 = 0

y0 = 0

Also;

4a = 12

a = 12/4

a = 3

Substituting x0 =0, y0 = 0 and a = 3 into the equation of the directrix above, we will have;

x = x0 - a

x = 0 - 3

x = -3

Hence,

the equation of the directrix is x = -3

So right now i'm doing prodigy and I got this question and I can't find out what it is can I have some help the question is The
Hunter-Best [27]

Answer:

x = 7

y = 4

Step-by-step explanation:

The sum of two numbers equaling 11 can be written as

x + y = 3

The difference of the two numbers equaling 3 can be written as

x - y = 3

Where x and y represent the unknown numbers

So now we have a system of equations

\left \{ {{x + y = 11} \atop{x - y = 3}} \right.

We can solve for y in the 1st equation by subtracting x on both sides

x + y = 11

y = 11 - x

We can plug the expression for y into the 2nd equation and solve for x

x - (11 - x) = 3

x - 11 + x = 3

2x - 11 = 3

2x = 14

x = 7

Now we can plug 7 for x into any of the equations and solve for y

1st equation:

7 + y = 11

y = 4

2nd equation:

7 - y = 3

-y = -4

y = 4

So, x = 7 and y = 4

Hope this helped!
