Question

Solve the inequality and graph the solution.
10s+10>
–
10
To draw a ray, plot an endpoint and select an arrow. Select an endpoint to change it from closed to open. Select the middle of the ray to delete it.

Answer 1

Solve: 10s + 10 > -10

Subtract 10 from both sides:
10s > -20

Divide both sides by 10:
s > -2

Solution: s > -2 (interval notation: (-2, ∞)).
Graph: open circle at -2 with a ray/arrow pointing to the right.
