Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "equals", etc. There are no inequalities shown in the question.
y > 5x - 2 y < 5x + 3 A.(4, 20) B.(-5, 25) C.(5, 28) D.(4, 23)
Although there is no graph, the number of solutions is 0.
Each linear equation is a line that divides the coordinate plane into three regions: one "above" the line, one "below" and the line itself. For a linear inequality, the corresponding equality divides the plane into two, with the line itself belonging to one or the other region depending on the nature of the inequality. A system of linear inequalities may define a polygonal region (a simplex) that satisfies ALL the inequalities. This area, if it exists, is called the feasible region and comprises all possible solutions of the linear inequalities. In linear programming, there will be an objective function which will restrict the feasible region to a vertex or an edge of simplex. There may also be a further constraint - integer programming - where the solution must comprise integers. In this case, the feasible region will comprise all the integer grid-ponits with the simplex.
Infinitely many
There are infinitely many solutions to 11x - 99 = 11(x - 9)
y > 5x - 2 y < 5x + 3 A.(4, 20) B.(-5, 25) C.(5, 28) D.(4, 23)
The part that is shaded represents all the possible solutions. An inequality has solutions that are either left or righ, above or below or between two parts of a graph.

For Formula 1. The point system is a score point that contributes to the drivers and constructors championship. Per race a driver can earn from 25 to 1 points. The current point system is 1st : 25 points 2nd : 18 points 3rd : 15 points 4th : 12 points 5th : 10 points 6th : 8 points 7th : 6 points 8th : 4 points 9th : 2 points 10th : 1 point 11th and below get 0 points

Solutions with pH below 7 are called acidic or 'acid'
Alkaline solutions have a pH higher than 7
