-2x + 6 - 13x + 16
= -15x + 22
The dog will need about 8 cans for the next six days.
The complete pattern is: 512, 256, 128, 64, 32, 16, 8, ( and extended ) 4, 2, 1!
I do this pattern in my head literally all the time!
horizontal shift: 3 units to the left
vertical shift: 4 units down
If he counts 76 feet, that means there’s 38 animals in total, because animals have 2 feet. 76/2=38
Hope that helps..!
