I Need Help Finding DE. I Do Not Know What Do To. Please Help Any Tips Will Be Appreciated:))

Answers

Answer 1

Given:

In triangle ABC, [tex]AB=11x-25,DE=4x+1[/tex].

To find:

The measure of DE.

Solution:

From the given figure, it is clear that D is the midpoint of AC and E is the midpoint of BC. So, the line segment DE is the mid-segment of the triangle ABC.

According to the triangle mid-segment theorem, mid-segment of a triangle is equal to half of its base.

Using triangle mid-segment theorem, we get

[tex]DE=\dfrac{1}{2}AB[/tex]

[tex](4x+1)=\dfrac{1}{2}(11x-25)[/tex]

[tex]2(4x+1)=11x-25[/tex]

[tex]8x+2=11x-25[/tex]

Isolate the variable terms.

[tex]8x-11x=-2-25[/tex]

[tex]-3x=-27[/tex]

[tex]x=\dfrac{-27}{-3}[/tex]

[tex]x=9[/tex]

The value of x is 9. So,

[tex]DE=4x+1[/tex]

[tex]DE=4(9)+1[/tex]

[tex]DE=36+1[/tex]

[tex]DE=36+1[/tex]

[tex]DE=37[/tex]

Therefore, the length of DE is 37 units.

Step-by-step explanation:

-3x + 4y = 16

y = 3/4x +4 A is a no

B are perpendicular so No

8x -2y = 20

y = 4x -10 C perpendicular to No

-3x +4y = 18

y= 3/4x + 18/4 yes slopes are the same so parallel

Your friend earns 7x dollars for
working x hours. How much does
your friend earn for working
16 hours? 40 hours?
16 hours $
40 hours $

Answers

Answer:

$112 for 16 hours

$280 for 40 hours

Step-by-step explanation:

Well, given that if 7x dollars are earned working for x hours (x is assumed to be 1), then $7 are earned for every hour worked. So we can pretty much multiply $7 (Money earned per hour) by 16 and then 40 (Hours worked). 7*16=112, and 7*40=280. And there are your two answers.

What is an equivalent equation for each given equation? Which one matches after you do your first step?
6x+10=23

Possible Answers:
A. 6x=13
B. 6x = 33
C. 23 = 10 -6x
D. -23 =-6x+10

Answers

I believe it would be A
Answer is:
A. 6x = 13

Explanation:
The next step after 6x+10=23 is to subtract 10 on both sides so you’ll be only left with your coefficient and variable which is 6x on one side and your constant on the other side.

6x + 10 = 23
6x + 10 - 10 = 23 - 10
6x = 23-10
6x = 13

help me!!

Answers

14x + 8 = 22. Okay, so first you want to subtract 8 from itself and 22. Once you did that you should get 14x = 14. Now, you need to divide 14 from both sides. 14/14 = 1. Meaning that x = 1. To check your answer, replace the x values with 1 and solve. 14 X 1 + 8 does equal 22.

its 1

The x=1 because 14 times one plus 8 is 22

What is the gradient of the line that passes through the points (0,0) and (3,3)?

Answers

Answer:

1

Step-by-step explanation:

the gradient is a value that indicates how much the x value increases as the y value increases. It can be written as

rise/run

or

change in  y value/change in x value

or

(y1-y2)/(x1-x2), where we know two coordinates (x1,y1) and (x2,y2).

We have two coordinates (0,0) and (3,3)

Therefore,

x1 = 0, y1 = 0

x2 = 3, y2 = 3

If we plug these values into the formula, it is [tex]\frac{3-0}{3-0} = \frac{3}{3} = 1[/tex]
