Answer:
The coordinates for B' would be (-6,1) and the coordinates for C would be (-8,-6)
Step-by-step explanation:
Point A was translated 2 left and 1 down to point A'
B = (-4,2)
-4 - 2 = -6 and 2 - 1 = 1 so B' would equal (-6,1)
C = (-6,-5)
-4 - 2 = -8 and -5 - 1 = -6 so C' would equal (-8,-6)
3x - 5y = 18 over
-10x + 5y = 10
Add them because the 5y's have the right symbols for us to add
-7x = 28
Divide
x = -4
Now you can plug in -4 for x in one equation, I would use the first equation!
3(-4) - 5y = 18
-12 - 5y = 18
Add 12
-5y = 30
Divide
y = -6
Your solutions are going to be:
x = -4
y = -6
To check your work plug x and y into one equation:
3(-4) - 5(-6) = 18
-12 + 30 = 18
18 = 18
Since 18 does equal 18 you know that your solution's work!
21,000+21,000=42,000
