Let the contribution of fatima = y

According to the question,

x + y = 100

For graph see the attachment

14. (i) Putting(0,2) in the equation, 0−2×2=4⇒−4=4 which is not true.

(ii)Putting (2,0) in the equation, 2−2×0=4⇒2=4 which is not true.

Nothing of them is a solution

15. See the second attachment

16. 12x2 -7x + 1

= 12x2 – 4x – 3x + 1

= 4x(3x – 1) -1 (3x – 1)

= (3x -1)(4x – 1)

17. 105×106 = (100+5)(100+6)

= 100×100 + 5×100 + 6×100 + 5×6

= 10000 + 1100 + 30

= 11130
