Answer:
The equation of the line that goes through points (1,1) and (3,7) is 
Step-by-step explanation:
Determine the equation of the line that goes through points (1,1) and (3,7)
We can write the equation of line in slope-intercept form
where m is slope and b is y-intercept.
We need to find slope and y-intercept.
Finding Slope
Slope can be found using formula: 
We have 
Putting values and finding slope

We get Slope = 3
Finding y-intercept
y-intercept can be found using point (1,1) and slope m = 3

We get y-intercept b = -2
So, equation of line having slope m=3 and y-intercept b = -2 is:

The equation of the line that goes through points (1,1) and (3,7) is 
Answer: 
Step-by-step explanation:
This is what it is as a mixed number

= 
= 
If you want it written in exponential form it would look like this:

When dividing 250,000 by 100, the digits in the quotient move by 2 places to the right.
<u>Step-by-Step explanation:</u>
Here we have , to find out that When dividing 250,000 by 100, the digits in the quotient move how many places to the right . Let's find out:
⇒ dividing 250,000 by 100
⇒ 250,000 / 100
⇒ 
⇒ 
⇒ 
Initially we had 250,000 of 6 digits and now after dividing 250,000 by 100, we have 2500 of 4 digits ! So , Number of places quotient shift to right is:
⇒ 
⇒ 
Therefore, When dividing 250,000 by 100, the digits in the quotient move by 2 places to the right.
x + 4 = 3x - 8, is assuming D is the midpoint, and therefore ED = DB.
all we know is that D is <u>somewhere</u> in EB.
