Find the slope of the line through the given points. (1,3) and (0,−9)

Thank you so much :)

Answers

Answer:

The answer is 12

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,3) and (0,−9)

The slope is

[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]

We have the final answer as

12

Hope this helps you

The slope of the line would be 12.

what value of x makes this equation true:

Answers

Answer:

x is 9

x is 9

can some please help me with this

Answers

Answer:

x = 25

Step-by-step explanation:

3x + 5 + 5x - 25 = 180 (collect like terms)

8x - 20 = 180 (add 20 on both sides)

8x = 200 (divide by 8 on both sides)

x = 25

Since they are supplementary that mean together they add up to 180 so that's why I added them together.

Question Says:-

An equilateral triangle is a triangle with three equal sides. The perimeter of an equilateral triangle varies directly with the length of one side. What is an equation that relates the perimeter p and length of a side?

Answer:-

See, let us consider the sides as l as per question.

And, perimeter as p as per question.

We know that:-

The sum of all the boundary gives us the perimeter of the figure.

It is Equilateral Triangle, so the equation will be:-

[tex]l + l + l = p[/tex]

Now, adding it up, we get

[tex]3l = p[/tex]

So, 3l=p relates the side and perimeter.

Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.

Angle one: 2x°, angle two: xº, angle 3: (X + 8)°

Answers

Sum of all angles in a triangle = 180°

Which means :-

∠1 + ∠2 + ∠3 = 180°

[tex]2x + x + x + 8 = 180°[/tex]

[tex]4x + 8 = 180°[/tex]

[tex]4x = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]x = \frac{172}{4} [/tex]

[tex]x = 43[/tex]

Angle 1 :-

= 2x

= 2 × 43

= 86°

Angle 2 :-

= x

= 43°

Angle 3 :-

= x + 8

= 43 + 8

= 51°

Carrie and nine of her friends go out to dinner. The total bill comes to $200. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip. What each person should contribute

Answers

Answer:

$3

Step-by-step explanation:

To find the value of the tip, multiply 200 by 15%.

200 x 15% = 30

Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)

30 / 10 = 3

Each person should contribute $3 toward the tip.

Each person will contribute $23.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Bill= $200

Tip= 15%

So, the amount of bill be paid after tip

= 200+ 200 x 15%

= 200+ 200 x 15/100

= 230

Now, each of them have to pay

= 230/ 10

= $23

Hence, Each of them paid $23.
