Answer: c
Step-by-step explanation:
because to find the average is to add all your numbers up and to divide them by how many numbers you have
and the median is the finding the middle which is the average you line them up from lowest to greatest value and cross one off from the beginning and one from the end until you are left either one or two values
Answer:
y = -3x + 9
Step-by-step explanation:
y = mx + b where m is the slope and b is the y intercept
The hypotenuse is on the same line as BC but twice as long. So extend that line up and it will cross the y axis at (0,9). 9 will be your y intercept.
To find the slope start at C and count up 9 and to the left 3 to get to B.
So the slope is rise/run or 9/(-3) = -3.
Final equation would be y = -3x + 9
Answer:
x = -9/2
Step-by-step explanation:
1. Divide 9 by -1/3:
÷
=
· 
= -27
2. Divide both sides by 2:
2(x - 9) = -27

(x - 9) = 
3. Add 9 to both sides:
x = 
(or 4.5 if you need it in decimal form)
