Answer:
The slope of dotted line 1.
The slope of reflection -1.
Step-by-step explanation:
No. A rational plus an irrational is always an irrational.
Answer:
259.2 cm³
Step-by-step explanation:
The volume of the dilated image is
(3/5)³ × 1200= 27/125 × 1200
= 259.2 cm³
The reflection over the y-axis only changes the sign of the x-component so the reflected point is A' (-3, -1)
<h3>How to reflect point A over the y-axis?</h3>
Here we can't see the options, so I will teach you how to reflect any point over the y-axis.
Any point on the X-Y plane is defined by its coordinates (x, y).
If we reflect this point over the y-plane, we only change the sign of the x-component of the point.
So after the reflection, we get the point (-x, y).
Then if we apply that reflection to point A (3, -1). We will get the reflected point:
A' (-3, -1)
