Answer:
Step-by-step explanation:
1)a) Abscissa of O 0
Abscissa of A 4
Abscissa of B -3 {opposite of 3}
Abscissa of C 3 {3 is the only positive integer like A}
Abscissa of D -4.5
Abscissa of E -6
Abscissa of F -1 {Midpoint of AE = (6+4)/2 = 10/2 = 5th number from -6 or 4}
b) OB = 3 units
DA = 8.5 {4.5 +4 = 8.5}
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)
k/5.2+81.9 = 47.2 // - 47.2
k/5.2-47.2+81.9 = 0
0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2
0.19230769*k = -(81.9-47.2) // : 0.19230769
k = (-(81.9-47.2))/0.19230769
k = 5.20000006*(47.2-81.9)
k = 5.20000006*(47.2-81.9)
Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>

Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own
