To solve and graph the inequality 5x ≤ 15, we can start by isolating x on one side of the inequality sign.

Dividing both sides of the inequality by 5, we get:

x ≤ 3

This means that any value of x that is less than or equal to 3 will satisfy the inequality.

To graph the solution, we can plot a closed circle at x = 3 and shade the region to the left of the circle, including the circle itself. This is because any value of x less than or equal to 3 will make the inequality true, and the circle at x = 3 is included in the solution because x can be equal to 3.

So the graph of the solution to the inequality 5x ≤ 15 looks like:

-------o--------

x ≤ 3

The bolded region includes the closed circle at x = 3 and all the values of x to the left of it.

\huge\text{Hey there!}



\mathsf{5x \leq 15}


\large\textsf{DIVIDE 5 to BOTH SIDES:}


\mathsf{(5x)/(5)\leq(15)/(5)}


\large\textsf{CANCEL out: \boxed{\bf (5)/(5)} because it give you 1}


\large\textsf{KEEP: \boxed{\bf (15)/(5)} because it help us know what is being compared to the x-value}


\mathsf{x \leq (15)/(5)}


\mathsf{x \leq 3}


\large\textsf{You have a(n) \boxed{\mathsf{closed}} shaded circle to your \boxed{\mathsf{left}}}




\huge\text{Therefore, your answer should be:}\\\\\huge\boxed{\mathsf{x \leq 3}}\huge\checkmark\\\\\huge\boxed{\large\huge{\textsf{You have a(n) \boxed{\mathsf{closed}} shaded circle to your \boxed{\mathsf{left}}}}}\huge\checkmark



\huge\text{Good luck on your assignment \& enjoy your day!}
