Find the length of the line segment that joins the points (2, 5) and (9, 8).

arsen [322]

Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(2,5)...x1 = 2 and y1 = 5
(9,8)...x2 = 9 and y2 = 8
now we sub
d = sqrt ((9 - 2)^2 + (8 - 5)^2)
d = sqrt ((7^2) + (3^2))
d = sqrt (49 + 9)
d = sqrt 58 <===

What is the distance between the points (2, -3) and (-6, 4) on the coordinate

VikaD [51]

Answer:

C) 10.63 units.

Step-by-step explanation:

To find the distance between any two points, we can use the distance formula:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the two points (2, -3) and (-6, 4). Let (2, -3) be (<em>x₁, y₁</em>) and let (-6, 4) be (<em>x₂, y₂</em>). Substitute:

$d=\sqrt{(-6-2)^2+(4-(-3))^2}$

Simplify:

$d=\sqrt{(-8)^2+(7)^2}$

Evaluate:

$d=\sqrt{64+49}=\sqrt{113}\approx10.63\text{ units}$

Our answer is C.

Answer:

x-intercept: (4, 0)

y-intercept: (0, 3)

Step-by-step explanation:

The intercepts of the equation can be found by setting each variable to zero and solving for the other. The graph will be a line through the intercept points.

<h3>Intercepts</h3>

Setting x=0 and solving for y, we have ...

4y -12 = 0 ⇒ y = 12/4 = 3

Setting y=0 and solving for x, we have ...

3x -12 = 0 ⇒ x = 12/3 = 4

The intercepts are ...

x-intercept: (4, 0)

y-intercept: (0, 3)

<h3>Graph</h3>

The line will go through these intercept points.

Mary needs to send out some letters and postcards. She went online at the United States Postal Service webpage and found out tha

MissTica

Answer:6 postcards and 9 letters

Step-by-step explanation:

First we label what we are looking for

Label number of postcard sent as x

Label number of letter sent as y

The we know Mary wrote to 15people, either as postcard or letter, so from this we make an equation

x + y = 15 (1)

The we know the amount Mary used to send all this is $6.15 which is also 615 cents

Then we know sending one postcard is 35cents, and we labeled number of postcards to be x

So total amount used for postcard will be 35x

And we know sending one letter is 45 cents, and we labeled number of letters to be y

So total amount used for letter will be 45y, so adding all this will be equals to the total amount used which is given as $6.15 also 615 cents, so making another equation

35x + 45y = 615 (2)

Solving the two simultaneously equations

x + y = 15 (1)

35x + 45y = 615 (2)

So we make y the subject of formula in (1)

y = 15 - x (3)

So we put (3) in (2)

Anywhere we see y, we put 15-x

35x + 45(15-x) = 615

35x + 675 -45x = 615

35x - 45x = 615 - 675

-10x = -60

divide both sides by -10

x = 6

So therefore, number of postcards is 6

Then we put x = 6 in (3)

y = 15 - x

y = 15 - 6

y = 9

So therefore number of letters is 9
