Check my explanation
Step-by-step explanation:
1. x=-7y
2(-7y)-8y=22
-14y-8y=22
-22y=22
y=-1;x=7, I used subtitution because that process was easier.
2. x=3+y
7(3+y)-y=-3
21+7y-y=-3
21+6y=-3
6y=-24
y=-4; x=-1, I used subtitution because that process was easier.
3. x=1 and y=1, I used elimination because that process was easier.
4. x-3=4x-9
-3x=-6
x=3; y=0, I used subsitution because that process was easier.
I think just two reflections would do it.
First we reflect around y = -x, the 45 degree line through the origin and the second and fourth quadrant.
Then we reflect through the y axis, x=0.
The composition of the two reflections is equivalent to a 90 degree clockwise rotation.
The distance depends on the time.
So now we need to find the constant of variation or the constant of proportionality.
To do so we must find y(the dependent variable) and x(the independent variable).
To find the constant(k) we must find y/x
Since y/x=k
Then 2.25/.75=k
k=3
