First, we can actually start off by dividing both sides by 3:
m + 5 - 2 = m + 3
m + 3 = m + 3
0 = 0
m has an infinite number of solutions
Answer:
Jada: 1
Diego: 4/3
Lin: 10/3
Step-by-step explanation:
To find MAD, you calculate the mean of the data sets (which you were given in this case), and then find the distance of each number in the data set from the mean. You then write all the distances down, and then find the mean of THAT. Now you have your MAD.
Example (Jada)
Data set: 4,4,4,6,6,6
Mean: 5
Distances: 1,1,1,1,1,1
Mean of distances (and therefore the MAD):
(1+1+1+1+1+1) divided by 6 = 1
I believe the slope of any vertical line is "undefined" because slope= rise(change in y values)/ run(change in x values).
Therefore, the slope for a horizontal line is
m= 0/(x2-x1).
However, for a vertical line the x-values are the values that are not changing. So, m= (y2-y1)/0. It is not possible to divide anything by zero. So, the slope of a vertical line is reported as m= undefined.
Any questions?
2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer
