Answer:
Step-by-step explanation:
Reflection across the y axis changes the x value.
Reflection across the x axis changes the y value.
This is counterintuitive, but it is correct.
A'
(-1,6)
B'
(-2,1)
C'
(-5,2)
Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction
I think it proved by the arc intercepting kl making it an interior alternate angle which means it equal to each other

Answer:
first number(x) = 2 second number(y)= 6
Step-by-step explanation:
This is an example of a simultaneous equation.
First write this word problem as equations, where x is the "first number" that you've mentioned and y is the "second number".
x + 2y = 14 (equation 1)
2x + y = 10 (equation 2)
This is solved using the elimination method.
We need to make one of the coefficients the same - in this case we can make y the same. In order to do this we need to multiply equation 2 by 2, so that y becomes 2y.
2x + y = 10 MULTIPLY BY 2
4x + 2y = 20 (this is now our new equation 2 with the same y coefficient)
Now subtract equation 1 from equation 2.
4x - x + 2y - 2y = 20 - 14 (2y cancels out here)
3x = 6
x = 2
Now we substitute our x value into equation 1 to find the value of y.
2 + 2y = 14
2y = 12
y = 6
Hope this has answered your question.
