Question 54776
solve each of the following inequality. express your final answer using interval notation. 
a) -2>-2y-10>-22 
Divide thru by -2 to get:
2<2y-5<11
Add 5 along the line to get:
7<2y<16
Divide thru by 2 to get:
(7/2)<y<8
Interval notation: (7/2,8)
----------------------
b) x/4+3 <4
Subtract 3 from both sides:
x/4 < 1
Multiply both sides by 4 to get:
x<4
Interval notation:
(-inf,4)
---------- 
C) x/8+5 >4
Subtract 5 from both sides:
x/8>-1
Multiply by 8 to get:
x>-8
Interval notation: (-inf,-8)
---------------
