The system of linear inequalities x + 10y ≤ 80, x ≥ 30 and y ≤ 4 is represented in a graph below

<h3>Graph of Linear Inequality</h3>

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality.

To solve this problem, we would require the use of graph which can easily be done with a graphing calculator.

x + 10y ≤ 80

x ≥ 30

y ≤ 4

The graph of the inequalities is attached below

Anyone got the answers for b and c
BaLLatris [955]
For letter b:

First times 5 on both sides to get rid of the denominator of 5

5 * y
— = 4 * 5
5

Then the answer is

y = 20


For letter c:

First move constants on one side, variables on the other

2g = 17 - 8

Then collect like terms:

2g = 9

Then divide both sides which would equal:

g = 9/2
