Respuesta :

Answer:

Option C

Step-by-step explanation:

The given inequality is

5x-1 < 19 and [tex]-3-x+1\le1[/tex]

Group similar terms to get:

5x < 19+1 and [tex]-x\le1-1+3[/tex]

5x < 20 and [tex]-x\le3[/tex]

Solve for x to get:

x < 4 and  [tex]x\ge -3[/tex]

The correct choice is C

Answer:

The correct graph of the solution to the given compound inequality is:

                                C

Step-by-step explanation:

  • The first inequality is given by:

   [tex]5x-1<19[/tex]

on adding 1 on both the side of the inequality we have:

[tex]5x<20[/tex]

on dividing both side of the inequality by 5 we have:

[tex]x<\dfrac{20}{5}\\\\x<4[/tex]

The graph of this inequality is the shaded region to the left of 4 with a open circle at 4( since the inequality is strict)

  • The second inequality is:

        [tex]-3-x+1\leq 1\\\\-3+1-x\leq 1\\\\-2-x\leq 1\\\\-2-1\leq x\\\\x\geq -3[/tex]

The graph of this inequality is the shaded region to the right of -3 and closed circle at -3 ( since the inequality is not strict i.e. a inequality with a equality sign )

Hence, the graph of the compound inequality is the set of all the points between -3 and 4 including -3 and excluding 4.
