21000=a+b
ax.075xt=6xbx.04xt
t cancels out
a=3.2b
21000= 3.2b+b
21000=4.2b
b=5000
a=16000

Answer:
(4.25, - 1.75)
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
(- 4.25, - 1.75 ) → (4.25, - 1.75 ) ← original point
Answer:
C. The average velocity of A is greater than B since it covers more distance.
Step-by-step explanation:
The y values on the graph represent velocity. Since A has a greater y-value than B for the entire 10 seconds, we know that the average velocity of A must be greater than B.
-2x + 8 = -4x + 1
- 1 -2x
7 = -6x
