You cannot change it on mobiles or ipods. But you can zoom in on laptop.or something big like desktop by setting and go zoom button and put it to 15X zoom :)
If you mean: y = -15x-4 then the slope is -15 and the y intercept is -4
If you mean: 2x2+15x+25 then it is (2x+5)(x+5)
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
If you mean: y = -15x+60 then 15x+y = 60 When y = 0 then x = 4 When x = 0 then y = 60 Coordinates of the line are: (4, 0) and (0, 60)
35x + 15x = 50x
15x-16x = -1
-9y-15x ---- -3
225x
zoom means enlarging or focusing on some thing
It can be, is there a specific meaning for Zoom?? It is a really good name if you want your fish to be zoom it can be. The meaning will just mean fast or speedy.
The GCF is 15x.
