Well she can buy 4 of the ten packs though that would give her five extra, she could buy 35 single note pads which would give her the exact amount, or she could buy 3 of the ten packs and 5 of the singles.
Y + 5x = 6
y + 5(-1) = 6
y + (-5) = 6
y - 5 = 6
y - 5 (+5) = 6 (+5)
y = 11
when x = - 1, y = 11
y + 5(0) = 6
y + 0 = 6
y + 0 (-0) = 6 (-0)
y = 6
when x = 0, y = 6
y + 5(1) = 6
y + 5 = 6
y + 5 (-5) = 6 (-5)
y = 1
when x = 1, y = 1
hope this helps
The area is 32m², because the area if it were a complete rectangle is 48m², but when the small portion that is missing, 16m², is subtracted from that, you are left with 32.
