To find the midpoint of a segment you need to use this equation:
(x1+x2/2, y1+y2/2) so if you plug in the numbers its...
9+(-7)/2, 2+(-9)/2
then solve to find x and y coordinate
x= 1 and y= -3.5
so the midpoint of CD is (1,-3.5)
Answer:
Let x and y be numbers of bicycles and tricycles, respectively
x
+
y
=
7 (i)
2
x
+
3
y
=
19 (ii)
Multiplying (1) by 2 gives:
2
x
+
2
y
=
14 (iii)
Subtracting (iii) from (ii) gives:
y
=
19
−
14
=
5
Substituting 5 for y in (i) gives:
x=7−5=2
Therefore there are 2 bicycles and 5 tricycles.

Answer: j = -0.45
Step-by-step explanation:
2.25 – 11j – 7.75 +1.5j = 0.5j – 1
We can group similar terms:
-11j +1.5j -0.5j = -1 - 2.25 + 7.75
-10j = 4.5
j = 4.5/-10
j = -0.45
Answer: j = -0.45
