Question 64805
The y-intercept value of the straight line 3x + 8y - 1 = 0 is:
PUT X=0..SINCE ON Y AXIS X=0....WE GET 8Y-1=0
Y=1/8....SO Y INTERCEPT = 1/8
 
What integer value will satisfy the following inequality?
3/5 < x/10 < 4/5 
MULTIPLY WITH 10
6<X<8
X=7 IS THE ONLY INTEGRAL VALUE

Find the interval of values of x that satisfies the inequality
3x - 1 < 8x - 6 
3X-8X<-6+1
-5X<-5
-X<-1
DIVIDING NOW WITH -1 WILL REVERSE THE INEQUALITY
X>1.............HENCE X =(1,INFINITY) IS THE SOLUTION SET

Factor and simplify the expression (12x - 8)/4
4(2X-3)/4=2X-3
