Answer:
D is the answer.
Step-by-step explanation:
You can see if a line is perpendicular by the slope. If the slope is COMPLETELY opposite from another by means of slope, the lines are perpendicular.
-1/4
4/1
...are opposite.
Answer:
shorter base = 6 yd
longer base = 8 yd
area of playground = 42 yd^2
Step-by-step explanation:
The question tells you that the shorter side is equal to the width, which is 6 yds. The bases of the triangles on either side are 1 yd. Since there are two, add 1 twice to 6 (6+1+1). This gives you 8 yd for the longer base. You're right about the area, just use the trapezoid area formula: 1/2h(a+b).
The slope is rise/run, so if you count it in the graph, you’ll see that it’s 3/2. Also, the y-intercept (where the graph crosses the y axis) is 1. So the answer is y=3/2x-1.

Answer:
A, B
Step-by-step explanation:
Divide both sides by 6 to see what those values should be:
x < 4
Of course all negative numbers are less than 4, so choices A and B are correct. The given positive numbers are not less than 4, so the remaining choices are not correct.
