As given m is a midpoint of ab. So am is half of ab.
So we can write

As given am = 3x+3 , ab = 8x - 6.
So





So x = 6.
So length of am = 3x+3 = 3*6 + 3 = 21
Answer:
y ≥ 2
Step-by-step explanation:
Range is the y-axis, so we have to look at the graph to find what numbers the line hits.
The line starts at y = 2 and goes up forever (the arrow indicates this), so that means that this line hits all y-values above 2.
Therefore the range is any y-value 2 or higher, so the answer is y ≥ 2.
Answer:
b
