Gene then reflected (-0.3, 7/10) over the y axis and then over the x axis what are the coordinates of the point after two reflec
lyudmila [28]

The coordinates of the point after the two reflections are (0.3,-7/10).

<h3>What is the reflection?</h3>

A reflection is a mapping from an isometric hyperplane with a set of fixed points acting as the reflection's axis or plane from a Euclidean space to itself. A figure's reflection creates its mirror image of that figure in the plane or axis of the reflection.

Given that, the point (-0.3, 7/10) is reflected over the y-axis and then over the x-axis respectively.

The coordinates of the point after the reflection in the y-axis are:
(0.3, 7/10)

Now, the coordinates of the point after the reflection in the x-axis are:
(0.3, -7/10)

Hence, the coordinates of the point after the two reflections are (0.3,-7/10).

Paul buys a number of large sacks of fertilizer costing $x each
Komok [63]
X times S = $27.  X is the cost of the large sacks and S is the amount of sacks.  Once they are multiplied it should equal $27.  If this is incorrect please let me know so I can try and correct mistakes made.
