graph and solve the system of inequality

See the attached file.

CheckPoint
11) Bayside Insurance offers two health plans. Under plan A, Giselle would have to pay the first $190, plus 40% of the rest. Under plan B, Giselle would pay the first $220, but only 30% of the rest. For what amount of medical bills will plan B save Giselle money? Assume she has over $220 in bills.
Giselle would save with plan B if she had more than $__ in bills. (round to the nearest whole number)

14) Solve and graph
-8?4x+4 and 4x+4<16
The solution is {x __ ? x < __}

15) Solve:
-6<x+5<10
The solution is {x l __ <x<__}

16) Solve
-11 ? 4 x -4 ? -3
The solution is {x l __ ? x ? __}
(Type an integer or a fraction)

18) Solve and graph the compound inequality.
X + 11 < -6 or x + 11 > 1
The solution of the compound inequality is
{x l x < __ or x > __}

19) Solve the compound inequality.
2x -5 ? -4 or 2x -5 ? 4
6 6
The solution of the compound inequality is
{x l x ? __ or x ? __}

22) Graph the inequality on a plane.
y > 2x

24) Graph the inequality on a plane.
8x -7 ? 15x + y

27) Graph the system of inequalities.
y ? -3
x ? 4

28) Graph the system of inequalities.
x + 3y ? 9,
3x + y ? 9,
x ? 0,
y ? 0.

Giselle would save with plan B if she had more than $_400_ in bills. (round to the nearest whole number)
Assume the amount is x dollars.
190+40%(x-190)>220+30%(x-220)
0.1x>220-66-190+76
x>400
