I don't know what the answer to number 1 is.

2. <u>Center</u>
25x² + 4y² - 50x - 24y - 39 = 0
           25x² + 4y² - 50x - 24y = 39
           25x² - 50x + 4y² - 24y = 39
            25(x² - 2x) + 4(y² - 6y) = 39
25(x² - 2x + 4) + 4(y² - 6y + 9) = 39 + 25(4) + 4(9)
25(x² - 2x + 4) + 4(y² - 6y + 9) = 39 + 100 + 36
25(x² - 2x + 4) + 4(y² - 6y + 9) = 175
                <u>25(x - 2)²</u> + <u>4(y - 3)²</u> = <u>175</u>
                    175           175        175
                    <u>(x - 2)²</u> + <u>4(y - 3)²</u> = 1
                        7           17

What is the answer for 5x-2x+8=2+6x+6?
Ede4ka [16]

5x - 2x + 8 = 2 + 6x + 6


Add like terms:

5x - 2x = 3x

2 + 6 = 8


3x + 8 = 6x + 8


To isolate the variable, subtract 6x from both sides of the equation:

3x - 6x = -3x


-3x + 8 = 8


Now subtract 8 from both sides:

8 - 8 = 0


-3x = 0


To finish, divide both sides by -3:

0 ÷ -3x = 0


The answer is x = 0


Hope this helps.

What is the equation of the quadratic function that has vertex (-3, 1) and passes through the point (-2, 4)?
Marat540 [252]
  • Vertex form: y=a(x-h)^2+k , with (h,k) as the vertex.

For this, we will be using vertex form. Firstly, plug the vertex into the vertex form equation:

y=a(x-(-3))^2+1\\y=a(x+3)^2+1

Next, we need to solve for a. Plug in (-2,4) into the x and y coordinates to solve for a as such:

4=a(-2+3)^2+1\\4=a(1)^2+1\\4=a+1\\3=a

Putting our equation together,<u> it's y=3(x+3)^2+1</u>

<u>*Additional section*</u>

  • Standard form: y=ax^2+bx+c

Converting to standard form as such:

y=3(x+3)^2+1\\y=3(x^2+6x+9)+1\\y=3x^2+18x+27+1\\y=3x^2+18x+28
