Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
(3x + 3 + 4x + 2) = 13
(7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
D is the midpoint of A and B
A = (0,s)
B = (r,0)
Add up the x coordinates to get 0+r = r. Then cut that in half to get r/2
Similarly, do the same for the y coordinates: s+0 = s ---> s/2
So the location of point D is (r/2, s/2)
Answer: Choice C
If you are asking for an equation for this statement, it would be y = x + 5
Answer:
Step-by-step explanation:
the median is the line inside the box which is 84
The acceleration is given by the slope of the line. This line passes through the points (0, 2) and (3, 5), so it has slope

which means the acceleration over this 3 second interval is 1 m/s^2.
