What is 0.285714 as a fraction not simplified
MrRa [10]

Answer:

2/7

Step-by-step explanation:

I am assuming that you mean 285714 repeating.

You just have to memorize or learn to recognize the order of decimal digits for fractions over 7, unless you want to do it algebraically.

1/7=0.142857 repeated

2/7=0.285714 repeated and so on

reflect (7,4) across the x-axis then reflect the result across the y-axis what are the coordinates of the final point
Andrews [41]

The coordinates of the final point after the two reflections is (-7, -4)

<h3>How to reflect a point across an axis?</h3>

For a point (x, y), a reflection across the x-axis gives the point (x, -y), while for a point (x, y) a reflection across the y-axis gives (-x, y).

In this case, we have the point (7, 4), first we reflect across the x-axis, so we get the point (-7, 4).

Now we reflect across the y-axis, so the sign of the y-component changes, and we get (-7, -4)

So the coordinates of the final point after the two reflections is (-7, -4).
