This is true because
is an odd function meaning that if you plug in a negative value, you will still get the same answer if you plugged in the absolute value of that number.
Answer:
50%
Step-by-step explanation:
If the distrubution is normal
and mean is the average score
that means that half of them should be equal to or below the mean

Answer:
t=1
Step-by-step explanation:
combine the one t and the 4t
16-2t=5t+9
subtract the 16
-2t=5t+9-16
-7t=9-16
-7t=-7
t=1
Look at the picture.
The point-slope form of a line:
We have the points (0, 1) and (2, 0). Substitute:
Answer: 
Answer:
(-3, -4)
Step-by-step explanation:
The solution is where the two lines intersect. Therefore, the x-coordinate is -3, and the y-coordinate is -4.
Another way to solve this would be to set the to equations equal to each other, so 2x+2 = -4. Therefore, 2x = -6, and x = -3. And from the second equation, y = -4.
