Answer:
y = 6
Step-by-step explanation:
if the triangles are congruent then the corresponding sides are equal.
so
4x + 1 = 13
4x = 13 -1
4x = 12
Therefore x = 3
Now
8x - 2y = 2x + y
y + 2y = 8x - 2x
3y = 6x
3y = 6 * 3
3y =18
Therefore y = 6
Answer:
(C) A'(4, 1)
Step-by-step explanation:
When a point is reflected across the x-axis, the following happens
- The x-coordinate remains the same
- The y-coordinate is transformed into its opposite (its sign is changed).
Given the Point A(4, –1)
When it is reflected, following the rules above
- The x-coordinate remains 4
- The y-coordinate changes from -1 to 1.
The coordinates of A' will therefore be: A'(4,1)
