Answer:

Step-by-step explanation:

So we know that the average of numbers is all of the numbers added up and divided by the total amount of numbers.

2721

+ 2557

-------------------

5278

.... AND SO ON.........

=14,894 is all of the number added together!!!

Then we count up the numbers= 5

14,894/5

=2978.8

I hope this helps!!!

What is the length of x? What is the length of EF? Only enter numbers in the answer boxes below:

Focus on triangles DFC and DFE:

They are both right triangles because DF is perpendicular to EC
DC=DE
DF is a common side

So, the two triangles are congruent. It follows that CF=FE, and in particular

$8x=3x+15 \iff 5x=15 \iff x=3$

And since x=3, the length of EF is

$EF=3x+15=3\cdot 3+15=24$

Question 2.2. Which ordered pairs make the inequality true?

Question 2.2. Which ordered pairs make the inequality true?2x + y > –4The solutions are (-1, 2) and (1, -5), look at the graph in the attachment.

Question 3.3. What is the slope of the line represented by the equation?

There is no equation

Question 4.4. What is the slope of the line represented by the equation 6x - 3y = 4?

Convert to slope-intercept form:

6x - 3y = 4

Subtract 6x to both sides:

-3y = -6x + 4

Divide -3 to both sides:

y = -6/-3x + 4/-3

Simplify:

y = 2x - 4/3

Now it's in slope intercept form, y = mx + b, where 'm' is the slope. So the slope here is 2.

Question 5.5. What is the simplified form of the expression?

15y - 3(4y + 10)

Distribute -3 into the parenthesis:

15y - 12y - 30

Combine like terms:

3y - 30
