1. 2x + 3y <= 6. Solve for ?
3y<= -2x + 6,
y = -2x/3 + 2.
2. b = 6c.
c = b/6.
3. Given: L = 15 cm.
2L + 2W > 80,
30 + 2W > 80,
2W > 80 - 30,
2W > 50,
W > 25 cm
4. I'm assuming both binomials =
-5x + 5.
6 > - 5x + 5 >= 10,
6 - 5 > -x >= 10 - 5,
1 > - 5x >= 5,
Multiply all terms by -5 and reverse
1/-5 < x <= 5/-5,
-1/5 < x <= -1.
1. Ans: y <= -2x/3 + 2.
