Question

Solve the inequality and graph the solution.
4+3t≤1
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: 4 + 3t ≤ 1
1. Subtract 4: 3t ≤ −3
2. Divide by 3 (positive): t ≤ −1

Solution: t ≤ −1
Interval notation: (−∞, −1]
Set notation: { t | t ≤ −1 }

Graph: place a closed (solid) endpoint at −1 and draw a ray going left (arrow pointing left).

(If using the ray tool: plot the endpoint at −1, make it closed, then select the left arrow direction.)
