Answer:

p=3

Step-by-step explanation:

The given parabola has equation ;

x^2=12y

The general formula for a parabola is;

x^2=4py

To find the value of p, we need to compare the coefficient of y in both equations;

\implies 4p=12

Divide both sides by 4;

\implies p=\frac{12}{4}

\implies p=3

Answer:

1 \frac{2}{5}

Step-by-step explanation:

= 5\frac{3}{5} / 2 \frac{2}{3}

= \frac{28}{5} / \frac{8}{2}

= \frac{28}{5} * \frac{2}{8}

= \frac{7}{5}

= 1 \frac{2}{5}

Determine the next step for solving the quadratic equation by completing the square.
Lady_Fox [76]

Answer:

-7/2 = -2(x-1/2)^2

Step-by-step explanation:

0 = –2x^2 + 2x + 3

Subtract 3 from each side

-3 = –2x^2 + 2x

Factor out the -2

-3 =- 2(x^2 -x)

Take the coefficient of x and divide by 2 and square it

-1 /2 = -1/2 ^2 = 1/4

Add it to each side  Remember the -2 on the outside so we need to multiply it by -2  

-2 *1/4 =  -1/2

-3 -1/2= -2(x^2 -x +1/4)

-7/2 = -2(x^2 -x +1/4)

-7/2 = -2(x-1/2)^2

Solve the system using substitution m=4n+11 -6n+8m=36
olchik [2.2K]
M=4n+11
-6n+8m=36

-6n + 8(4n+11) = 36
-6n + 32n + 88 = 36
26n = 36 - 88
26n = -52
n = -2

m = 4n+11 = 4(-2) + 11 = 3

Answer: (3, -2)

Someone please help me. Thank you!
Marysya12 [62]

Answer:

y = -1/2x

Step-by-step explanation:

Okay, so you probably heard of the slope-intercept form, y = mx + b. We have to use that formula to create a line that goes through (2,1), because thats the bisector.

Let's have our point start at the origin, (0,0). This you make our equation of y=mx+b   <u>into</u>   y = mx + 0. Since it's 0, let's just <em>drop</em> it out of our equation.

So now for slope. Rise/Run is what we're going to use to create our slope. Since we started at the origin, our slope is going to be negative. We can go down one over two from the origin to get to points (2,1) so why can't that be our slope? We're rising -1, and running 2, making our slope -1/2. In the equation, it would be y= -1/2x + 0, which can be simplified into y = -1/2x

It's a lot of writing and explaining, so I hope this helps! Try asking your teacher just to make sure it's correct.
