The answer to the question
Answer:
Step-by-step explanation:
Solve by substitution. Solve the second equation for x:
Insert the value of x into the first equation:
Solve for y. Simplify multiplication using the distributive property:
Subtract 190 from both sides:
Isolate the variable to find its value. Divide both sides by -29:
Now take the value of y and insert back into either equation to solve for x:
Subtract 6 from both sides:
Divide both sides by 5:
Therefore, the solution to the system is .

First find the value of m by solving the inequality.
Solving the inequality we get value of m: m>-4
Now, for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.
Step-by-step explanation:
We need to draw the graph of the solution set for the following inequality.
First we will solve the inequality and find value of m
Adding -18 on both sides
Dividing both sides by -3 and reversing the inequality i.e < is changed into >
So, value of m is: m>-4
So. for drawing the graph, a dotted line will be on -4, as values greater than -4 are included in the graph. and all the portion on right side of -4 is included in the graph.
The graph is shown in figure attached.
