Answer:
x = 20 y= 12
Step-by-step explanation:
x+y=32
x−y=8
Add the two equations together to eliminate y
x+y=32
x−y=8
----------------
2x = 40
Divide each side by 2
2x/2 = 40/2
x = 20
We know x so we can find y
x+y = 32
20+y = 32
20+y-20 = 32-20
y= 12

Answer:
<em>Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.</em>
<em>Choice 1.</em>
Step-by-step explanation:
<u>Reflection over the x-axis</u>
Given a point A(x,y), a reflection over the x-axis maps A to the point A' with coordinates A'(x,-y).
The figure shows triangles ABC and A'B'C'. It can be clearly seen the x-coordinates for each vertex of both triangles is the same and the y-coordinate is the inverse of it counterpart. For example A=(5,3) and A'=(5,-3)
Thus, the transformation from ABC to A'B'C' is a reflection over the x-axis.
Choice 1.
Answer:
All integers are whole numbers
Step-by-step explanation:
Integers include all whole numbers and their negative counterpart (basically numbers that are NOT fractions or decimals).
Whole numbers don't include negative numbers (as negative numbers are rational numbers).
