Question

Solve the inequality and graph the solution.
2(c+4)>4

Answer 1

9514 1404 393

Answer:

c > -2

Explanation:

We see that 4 has been added to c, and the sum multiplied by 2. Undoing these operations in reverse order, we first divide by 2:

c +4 > 2

Then we subtract 4:

c > -2

This does not include the "equal to" case, so the circle at c=-2 is open.
