1) -2 < 6 - 4x < 8
-2 - 6 < -4x < 8 - 6
-8 < -4 x < 2
8 > 4x > -2
-2 < 4x < 8
-2/4 < x < 8/4
-1/2 < x < 2
Hp = { x | -1/2 < x < 2 , x € R }
2) Scientific notation
a x 10 ^ n
Where
1 _ <a <10
0, 0000245
= 245 / 10,000,000
= 245/10 10 7
= 245 x 10 ^ -7
= 2.45 x 10 ^ 2 x 10 ^ -7
= 2.45 x 10 ^ -5
3) Discharge = volume: time
Discharge = 450 m ^ 3: 50 minutes
Discharge = 9 m ^ 3 / minute
