Answer:

x = 4/7

y = 60/7

Step-by-step explanation:

3x + 4y = 36

y = x + 8

Substitute the second equation into the first since it already has the y isolated for you:

3x + 4(x + 8) = 36

3x + 4x + 32 = 36

7x = 4

x = 4/7

Take the answer you got from the equation above and plug that into the second equation:

y = 4/7 + 8

y = 60/7

To check just LS/RS both equations:

3(4/7) + 4(60/7) = 36

12/7 = 240/7 = 36

252/7 = 36

36 = 36

LS = RS

60/7 = 4/7 + 8

60/7 = 60/7

LS = RS

The equation of the parabola is:

$y = 24x^2$

---------------------------

The <em>equation </em>of a parabola of vertex (h,k) and focus (0,f) is given by:

$y = 4p(x - h)^2 + k^2$

Vertex at the origin means that $h = 0, k = 0$ .
Focus (0,6) means that $p = 6$

Thus, the equation of the parabola is:

$y = 4p(x - h)^2 + k^2$

$y = 4(6)(x - 0)^2 + 0^2$

$y = 24x^2$
