It is D. After realizing the inequality to y>1, you can find D. To get y>1, you can see that there is a dotted line so there is no equal to and then you find that all y values are greater than 1 so we figure out it is D!
4.986 because you divide the 1 in fourths don't rweally know the answer
To find a perimeter add all the sides of the shape. so 12+9+15 is 36. the perimeter of the triangle is 36
I think it’s -3,1 I’m not sure though!
