Answer:
448
Step-by-step explanation:
Assuming that each notebook contains the same amount of pages, you must first divide 512 by 8. You will find that each notebook contains 64 pages. Then, to find how many pages he filled with notes after completing 7 notebooks, multiply 64 by 7. You should get the answer, 448.
1. -8x = 3x
-11x = 0
x= 0
y= 3(0)= 0
(0, 0)
2. -7x = -4x - 12
-3x = -12
x = 4
y = -7(4)= -28
(4, -28)
