Solving and Graphing a Compound Inequality Involving "And" | Math with Mr. J

What is the first step to isolate the variable 'c' in the compound inequality -9 <= 4c - 5 < 7?

• Add 5 to all parts

• Subtract 5 from all parts

• Divide all parts by 4

• Multiply all parts by 4

After performing the first step (adding 5 to all parts) to solve the compound inequality -9 <= 4c - 5 < 7, what is the resulting inequality?

• -4 <= 4c < 12

• -14 <= 4c < 2

• -9 <= 4c < 12

• -4 <= 4c < 7

What is the final solution for 'c' in the compound inequality -9 <= 4c - 5 < 7?

• -1 < c <= 3

• -1 <= c < 3

• c < -1 or c >= 3

• c <= -1 or c > 3

When graphing the solution -1 <= c < 3 on a number line, which statement correctly describes the circles used at -1 and 3?

• An open circle at -1 and a closed circle at 3

• A closed circle at -1 and an open circle at 3

• Open circles at both -1 and 3

• Closed circles at both -1 and 3
