Answer:

-0.5 or -1/2

Step-by-step explanation:

The equation for slope is y₂-y₁ / x₂-x₁.

It should work with all of the points given. Any of the 2 points you choose will give you the slope -0.5 or -1/2.

The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

The average slope of a straight line ;

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

So slope  associated with two points (-2,1) , (0,0)

⇒ (0 - 1) / (0 + 2)

⇒ -1/2

Since all three points are in a straight line so slope must be the same.

Hence "The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2".

Answer:

The midpoint is (-1,7)

Step-by-step explanation:

To find the midpoint

Add the x terms together and divide by 2 to get the x coordinate

(2+-4)/2 = -2/2 =-1

Add the y terms together and divide by 2 to get the y coordinate

(5+9)/2 = 14/2 =7

The midpoint is (-1,7)

    = 180π cm

Each guest needs 70 cm, thus

180π ÷ 70 ≈ 8.078 ← number of guests at 1 table

18 × 8.078 = 145.404 ← number of guests at 18 tables.

There is enough tables to seat 145 guests

Answer:

205 litres

Step-by-step explanation:

Given:

Volume of water is given as:

[tex]V=100+20m[/tex] (in litres)

m is the time in minutes spent filling water in Eduardo's pool.

To find:

Volume of water in the pool after the water is filled for [tex]5\frac{1}{4}[/tex] minutes.

Solution:

Here, volume of water in the Pool (in litres) is given by the equation:

[tex]V=100+20m[/tex] ....... (1)

Where m is the time for which Eduardo fills the pool.

Here, we are also given that

m = [tex]5\frac{1}{4}[/tex] minutes = [tex]\frac{5\times4+1 }{4}=\frac{20+1}{4}=\frac{21}{4}[/tex] minutes

And we have to find the value of V after [tex]\frac{21}{4}[/tex] minutes.

Let us put the value of m as [tex]\frac{21}{4}[/tex] minutes in the equation (1) to find the value of V.

[tex]V=100+20m\\\Rightarrow V = 100 + 20 \times \frac{21}{4}\\\Rightarrow V = 100+105\\\Rightarrow \bold{V = 205\ litres}[/tex]

So, the volume of water in the pool after [tex]\frac{21}{4}[/tex] minutes is 205 litres.

Step-by-step explanation:

Let x be the total number of M&Ms in the bag.

0.75x = 36 because 75% of the M&Ms are red and there are 36 red M&Ms.

We can divide both sides by 0.75, getting x = 48.

Therefore, there are 48 M&Ms in the bag.

Answer: Hi!

To find the distance of the point from each axis, all we have to do is look at the x and the y coordinates of the points. If we wanted to find the distance that point P was from the x axis, we would look at our y - coordinate:

(x, y) = (3, 4) So, point P is 4 units away from the x -axis.

Now we need to look at the x - coordinate to find the distance that point P is from the y axis:

(x, y) = (3, 4) So, point P is 3 units away from the y - axis.
