Answer:
|x - 5| = 2
Step-by-step explanation:
Since we are not given a zero on the number line, we do the following:
Average = midpoint between two numbers on the number line
For this number line,
Average = 3 + 7 ÷ 2
Average = 5
Next we find how many units away are each number from the middle:
3 is 2 units away from 5
7 is 2 units away from 5
Units away = 2
Let's use the formula:
|x - average| = Units away
Substitute values into equation
|x - 5| = 2
Now we solve
Solve for x over the integers:
|x - 5| = 2
Split the equation into two possible equations:
x - 5 = 2 or x - 5 = -2
Add 5 to both sides:
x = -5 + 5 = 2 + 5 or x - 5 + 5 = -2 + 5
Answer:
x = 7 or x = 3
LOOK AT THE GRAPH AND NUMBER LINE
In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:
For each additional city mpg, the highway value goes up by
0.9478 mpg.
And It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.
According to the statement
we have given that the relationship between the number of miles per gallon on the highway in the graphical representation and that in the city for some cars.
And we have to give some reasons for the given statements.
So, For this purpose, we know that the
A. In this statement we have to tell that the what is shown in the given relationship in the graph.
So, For each additional city mpg, the highway value goes up by
0.9478 mpg.
And the second statement is
B. I this we have to tell the intercept of the plane in the given Relationship.
So, It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.
So, In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:
For each additional city mpg, the highway value goes up by
0.9478 mpg.
And It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.
