The graph to answer the question and the answer choices.

  y ≥ 3x -1; x +3y ≤ 6

Step-by-step explanation:

Both lines are solid, so the only viable choices are those with "or equal to" in the comparison operators: the 2nd and 4th choices.

The line with a slope of +3 is shaded above the line, so that will correspond to the inequality ...

  y ≥ 3x -1 . . . . . . . . . . found only in the 4th choice.

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
