Answer:
x<2.5
Step-by-step explanation:
-4x +5>-5
-4x>-5-5
-4x>-10
x<10/4(on multiplying (-)ve sign both the sides inequality changes)
x < 2.5
9 - x < 8 => -x < 8 - 9 => -x < -1 => x > 1
9 - x > 3 => -x > 3 -9 => -x > -6 => x < 6
So the number is between 1 and 6, notation 1 < x < 6
X^2-11x+28=0
(x-7)(x-4)=0
x-7=0
x=7
x-4=0
x=4
