In the graph, the highest or lowest point of a parabola is the vertex. The vertex of the graph of y=x2 is (0,0). If a>0 in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola. so the vertex and the equations will lead to finding a parabola.

Find the value of y when x equals 26 x+4y=54
pishuonlain [190]

Factor out the common term "2".

2(13x+2y) = 54

Now, divide both sides by 2.

13x + 2y = 54/2. <-- <u>We could not divide into a whole number so it's a fraction.</u>

<u />

Simplify 54/2 to 27.

13x + 2y = 27 <--- <u>Since we have a whole number without a letter, we are done with that side.</u>

<u />

Now, we subtract 2y from both sides.

13x = 27 - 2y

Divide both sides by 13.

x = 27 - 2y/13.

<h3>Therefore, we get <u>x = 27 - 2y/13</u></h3>

That would be our final answer.

Good luck on your assignment!
