Find the pair of fractions that equal the same decimal:

8/4 = 2, 15/10 = 1.5 Not equal

8/10 = 0.8, 4/20 = 0.2, Not equal

6/4 = 1.5, 20/10 = 2, Not equal

8/6 = 1.33, 20/15 = 1.33 Equal.

The answer is 8/6 = 20/15

I'm not sure, but I believe your answer would be

8/10 = 4/20

Forgive me if I'm wrong, but the others seem to say the same thing that this answer doesn't.

Which equation represents a parabola that opens upward has a minimum at x=3 and has a line of symmetry at x=3

umka2103 [35]

Answer:

$y=x^2-6x+5$

Step-by-step explanation:

Let us consider the equation $y=x^2-6x+5$

For a quadratic equation in a standard form, $y=ax^2+bx+c$ , the axis of symmetry is the vertical line $x = \frac{-b}{2a}$ .

Here in this case we have, $a=1, b=-6 , c =5$

Putting the values we get,

$x = \frac{-(-6)}{2\times 1} = \frac{6}{2} =3$

We can see that the axis of symmetry is x=3 and the graph is giving minimum at x=3.

Therefore, the required equation is $y=x^2-6x+5$ . Refer the image attached.
