A(-5,3) and B(-5, 7)

What is the slope of AB?

C(1, 9) and D(-10, 9)

What is the slope of CD?

What are the lines? (parallel, perpendicular or neither)

BRainliest Plus 50 PointsDetermine Whether The Lines AB And CD Would Be Parallel, Perpendicular, Or Neither?A(-5,3)

Answers

Answer 1

Answer:

Perpendicular

slope Ab = undefined

slope Cd = 0

Step-by-step explanation:

slope AB = undefined, a vertical line has no slope

slope CD = 0 (a horizontal line has no slope)

Answer 2

Answer:

AB: Undefined

CD: 0

Perpendicular

Step-by-step explanation:

Slope is the change in y over the change in x

(sometimes called "rise over run")

Formula looks like this:

[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]

First let's find the slope of AB

[tex]\frac{7-3}{-5 --5 }[/tex]

[tex]\frac{7-3}{-5 +5 }[/tex]

[tex]\frac{4}{0}[/tex]

Undefined

Then the slope of CD:

[tex]\frac{y_{2} -y_{1}}{x_{2} - x_{1} }[/tex]

[tex]\frac{9 -9}{-10 - 1 }[/tex]

[tex]\frac{0}{-11 }[/tex]

0

         If they are parallel they will have the same slope, perpendicular lines have negative reciprocals as the slope, and neither is neither

         Comparing the slope of our lines lead us to know that the two lines are perpendicular because AB is vertically up + down and CD is horizontally right + left

I hope this is correct and helps, have a nice day :D

when 7 is added to 3 times a number, the sum is multiplied by 2 and 15 is subtracted what is the final answer

Answers

Answer:

2(3x+7) -15

Step-by-step explanation:

Let x = unknown number

7 is added to 3 times a number

3x+7

Multiply the sum by 2

2(3x+7)

Subtract 15

2(3x+7) -15

Answer:

Let the required number be " x "

Now, 7 is added to 3 times a number : (3x + 7)

Next, the sum is multiplied by 2 : 2(3x + 7)

And then, 15 is substracted from it : 2(3x + 7) - 15

2(3x + 7) - 15 is the final answer.

Point V is on the line segment UW. Given VW=5x-4, UV=2x, and UW=5x, determine the numerical length of VW

Answers

So UV+VW=UW
Or 2x+5x-4=5x
So 7x-4=5x
This means that x is generally a low amount as x has to be less than 3 (as 3x7, 21-4=17 and 3x5=15.)
I then tried to input 2 and got 14-4=10 which is correct.
So x=2
We then input x=2 into 5x-4 for the answer.

5(2)-4
10-4
6

The final answer is 6

* Find the cast price of the following: a) selling price 55 profit 10% c) selling price $680, loss 15% b) selling price $558, profit 24% d) selling price $11.78, loss 5%​

Answers

Step-by-step explanation:

• C. P = Cost Price.. , S. P (Sell Price) ,

→ C.P = 100×S.P/100+Profit (when profit)

(a) C.P = 100 × 55/100 + 10 = 5500/110

C.P » $ 50(b) C.P = 100 × 558/100+24 = 55800/124

C.P » $ 450→ C. P = 100 × S.P/100 - loss (when loss)

(c) C. P = 100 × 680 / 100 - 15 = 68000/85

C. P » $ 800

(d) C. P = 100 × 11.78 / 100 - 5 = 1178/95

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.​

Answers

Answer:

[tex]9n - 12 \rightarrow \frac{1}{3} (9n - 12) \\ = \frac{3}{3} (3n - 4) \\ l = 3n - 4[/tex]

Question:

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.

Solution:The perimeter of an equilateral triangle is 9n - 12.We know, perimeter of a triangle is the sum of the three sides of the triangle.Also, in an equilateral triangle, all the sides are equal.Therefore, the length of each side of the triangle

[tex] = \frac{9n-12}{3} \\ = \frac{3(3n - 4)}{3} \\ = 3n - 4[/tex]

Answer:

The length of each side of the triangle is 3n-4.

Answer:

no solution

Step-by-step explanation:

[tex]\frac{x}{3}[/tex] + 6 = 2([tex]\frac{x}{6}[/tex] + 5) ← distribute parenthesis by 2

[tex]\frac{x}{3}[/tex] + 6 = [tex]\frac{x}{3}[/tex] + 10 ( subtract 6 from both sides )

[tex]\frac{x}{3}[/tex] = [tex]\frac{x}{3}[/tex] + 4 ( subtract [tex]\frac{x}{3}[/tex] from both sides )

0 = 4 ← False statement

The following represents slopes of two lines. Which answer choice describes the two lines? m = 7 and m = -7

Answers

Answer:

m = 7 can also be y=7x+1 is positive and shows acceleration or ascending lines steep y axis 1 and x axis 0 ascending to 1 or above and when y = 7  x =1 see attached.

m = -7 is negative and shows deceleration of 1 as we add 1 here too. Or can be any number for y intercept see attached.

Step-by-step explanation:

Answer:
The slopes of two lines are given as:

m = 7
m = -7

A line with a positive slope of 7 rises as it moves to the right, and a line with a negative slope of -7 falls as it moves to the right.

Therefore, the two lines have slopes that are opposite in sign and have the same magnitude. This means they are two straight lines that are mirror images of each other, reflected across the x-axis.

Graphically, they would look like this:

yaml

^

|
|
------ + ------ (m = 7)
|
|
|
v

v
|
|
|
------ + ------ (m = -7)

Therefore, the two lines are parallel to each other and have a distance between them

The length of a side of a square is 4x – 1.
Express the area of the square in terms of x.

Answers

Answer:

16x^2 - 8x + 1

Step-by-step explanation:

1. The area of a square can be represented as s^2 or (s)(s), where s = side.

2. (Solving)

Step 1: Set up expression

[tex](4x-1)^2[/tex] [tex](4x-1)(4x-1)[/tex]

Step 2: Apply the FOIL method (first, outside, inside, last)

[tex](4x)(4x)+(4x)(-1)+(-1)(4x)+(-1)(-1)[/tex] [tex]16x^2 -4x -4x +1[/tex]

Step 3: Simplify.

[tex](16x^2)+(-4x-4x)+(1)[/tex] [tex]16x^2 -8x + 1[/tex]

Therefore, the area of the square in terms of x is 16x^2 - 8x + 1.
