Are you looking for the length from E to F?
HERE IS YOUR ANSWER HOOMAN:
8
STEP BY STEP EXPLANATION FAM:
We have a set of four numbers and the mean is 5. We can see that the sum of the values is 20:
=5
We have another set of three numbers whose mean is 12. We can write that as:
=12
To find the mean of the seven numbers together, we can add the values together and divide by 7:
=
=8

The answer would be -6x +s -14
The answer to the first question of the attached document is option 1. We obtain the answer subtracting the term n from the series with the term n-1.For example:
-3 - (- 5) = 2
-1 - (- 3) = 2
1 - (- 1) = 2
So you can see that the common difference is the 2.
The answer to the second question is option 3:
y = | x + 7 |
We can confirm it by substituting values in the equation.
For example:
if we do y = 0 then x = -7
if we do x = 0 then y = 7.
As corresponds in the graph shown.
Remember also that as a general rule yes to the equationy = | x | whose vertex is in the point (0,0) we add a positive real number "a" of form y = | x + a | then the graph of y = | x | will move "to" units in the negative direction of x.
The answer to the third question is option 4.
The quotient of x and "and" is constant.
k = y / x
Rewriting:
y = kx
You can see that it corresponds to the equation of a line that passes through the origin, this means that and is proportional to x and both vary directly
Your answer is 250,000. There are two ways to do this problem.
1) Solve 500/4 to find out how many sheets of paper you get per every dollar. — Your answer is 125 sheets for $1. Then you multiply that answer by 2000, and get 250,000. Which means you get 250,000 sheets of paper for $2000.
2) You can divide 2000 by 4 & that gets you 500, you can then multiply that by 500 & you will get 250,000.
Hope this helps.
