A triangle undergoes a sequence of transformations.
First, the triangle is dilated by a scale factor of 1/3 about the origin. Then the triangle is reflected over the x-axis. Finally, the triangle is translated left 3 units and up 2 units.

Subtract 5y - 8 from 2y + 8
To subtract two numbers, we can do it like this:
10 - 4 = 10 + (-4)
That is, add the first number with the second number with its sign changed. For simple numbers, it does not make much difference, but for algebraic expressions, it can help a lot.
To subtract both binomials, we write the first plus the second with changed signs:
2y + 8
-5y + 8
---------------
-3y + 16
The result of the subtraction is -3y+16
Answer:
1. X=-3, Y=0
2. all real numbers
Step-by-step explanation:
1.
2x+x+3=-6
3x+3=-6
3x=-9
x=-3
y=-3+3
y=0
2.
6x-2(3x-6)=12
6x-6x+12=12
0=0
All real numbers
