Apart from 7 the other 3 all equal
Answer:
Midpoint (9,1,(8-4) = (8.5, -1.5)
step-by step:Midpoint (9,1, 8-4)=(xA+xB2,yA+yB2)=(9+82,1+−42)=(172,−32)Midpoint of a line segment (9,1, 8-4)= (8.5, -1.5)
Once cross multiplied you end up with this:
15x+75=20x−30
Next subtract 20x from both sides.
15x+75−20x=20x−30−20x
−5x+75=−30 -----------> Answer
Now subtract 75 from both sides
−5x+75−75=−30−75
−5x=−105
Now divide by -5 on both sides.
-5/-5x = -105/-5

x = 21 --------------> ANSWER</h3>
Answer:
B.
Step-by-step explanation:
The function is positive when it is above the x-axis
The following x values are where the function has positive y coordinates:
(-2,0)
(4,inf)
The function is negative when it is below the x-axis
The following x values are where the function has negative y coordinates:
(-inf,-2)
(0,4)
So you should see all of these intervals listed in choice B
