g(x) is basically f(x) but flipped or reflected over or the y-axis. We can achieve this effect by negating f(x), or -f(x).
g(x) = -f(x) = -|x|
I believe it is 52. All you do is take 156 and divide it by 3. You get 52. In order to check if this is true, you take 52 and add it 3 times.
Yes, it is.
Formula X+1=3/4y is linear.
In the image move the point 3 left and 2 up then you should have your answer
270, 360 | 2
135, 180 | 3
45, 60 | 3
15, 20 | 5
3, 4
2 * 3 * 3 * 5 = 90
The greatest common factor of 270 and 360 is 90.
