Answer:
20
Step-by-step explanation:
To find the mean, add up all the numbers in the data set, and then divide by the number of terms in the data set
<em>Add </em>
Add up the numbers in the data set
17+24+26+13
80
<em>Divide </em>
Divide by the number of terms in the data set
In this case, there are 4 terms (17, 24, 26, 13)
80/4=20
The mean of the data set is 20
Answer:
(8, -22)
Step-by-step explanation:
The tables each contain four (x,y) points of a straight line. You can see that for every increase of x by 2, y decreases by 8 in the first one (observe 26, 18, 10 2), and decreases by 6 in the second.
If you continue the table with x=4, 6 and 8, you get y=-22 in both cases for x=8. That is the intersection, so the solution is (8,-22).
Added a graph. The equations are y=10-4x and y=2-3x respectively. Hope you understand a bit of this (brief) explanation.
It will be negative 2,cause your equation is already in general form but we can't have a negative on a, so we should changed it on their opposite sign, so 2 will be negative
