The equation of line is y = -x + 6

What is Equation of line ?

A straight line's general equation is y = mx + b, where m denotes the gradient and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.

The given point are (5, 1) and (7, 11)

We know, the equation of line is,

y = mx + b

where, m = slope

            b = y-intercept

First, find slope i.e m

we know the formula of slope (m) = (y2 - y1) / (x2 - x1)

The points, (x1, x2) = (5, 1) and,

                   (y1, y2) = (7, 11)

put these values in slope formula,

m = (11 -7) / (1 - 5)

   = 4 / -4

m = -1

we get the slope is -1

Next, find y-intercept i.e 'b'

for that, take any one point I'm taking (5, 1) and put these in equation ,

y = mx + b

1 = -1 * 5 + b

1 = -5 + b

b = 6

Now, put slope (m) and y-intercept (b) value in ,

y = mx + b

we get,

y = -x + 6

Hence, the equation of line is y = -x + 6

Step-by-step explanation:

Meow island get's their population multiplied by 3 per year

Purr island get's and additional 4 cats per year

The population of cats on each island in the mathematical form is:

Meow island:

f(0) = 2

And,

f(x) = 3f(x - 1)

Where x is the number of years from x = 1, 2, 3 ,,,,

Purr island:

y = 4x + 2

Where x is the number of years from x = 0, 1, 2, 3 ,,,,

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

We will make ordered pair of number of years x and number of cats y as

(x, y).

Meow island:

We see that the number of cats is increasing 3 times the previous number of cats.

So,

f(0) = 2

And,

f(x) = 3f(x - 1)

Where x is the number of years from x = 1, 2, 3 ,,,,

Purr island:

(0, 2), (1, 6), (2, 10), (3, 14) ....

The equation for the table.

y = mx + c

m = (6 - 2) / (2 - 1) = 4/1 = 4

(0, 2) = (x, y)

2 = 4 x 0 + c

c = 2

Now,

y = 4x + 2

Thus,

The population of cats on each island in mathematical form is given above.

The distance between the ordered pairs is 4 units

What is distance formula?

Distance formula calculates the distance between two coordinates. it calculates the straight line distance between two points. The formula can be given as [tex]distance=\sqrt{(c-a)^{2}+(d-b)^{2} }[/tex] for the coordinates (a, b) (c, d)

We are given the ordered pair (w+2,m) and (2t,c-3)

We are given the value w = 6, m = 3, t = 4 and c = 10.

Substituting the values in the pairs

We get,

(6+2,3),(2(4),10-3)

(8,3),(8,7)

We use distance formula to find the distance

[tex]d=\sqrt{(8-8)^{2} +(7-3)^{2} }\\ d=\sqrt{4^{2} }\\ d=4[/tex]

Hence the distance between the ordered pairs is 4 units.

The result of the expression given as 6x/(-2) is -3x

From the question, the expression is given as

6x/(-2)

The above expression is a quotient expression

So, we start by rewritting it as a product

6x/(-2) = 6x * 1/(-2)

Remove the bracket

So, we have the following equation

6x/(-2) = 6x * 1/-2

Triangles are close figures with three sides and three internal angles. Two triangles are congruent when they share sides with same lengths and angle and side distributions, then AC ≅ XZ, BC ≅ YZ and AB ≅ XY. The perimeter is the sum of the lengths of the three sides of the figure, then:

p = 10 cm + 12 cm + 14 cm

p = 36 cm

A triangle is a three-sided polygon that consists of three edges and three vertices.

Two triangles are congruent if all of their sides are the same.

By data triangle ABC and triangle XYZ are congruent.

In triangle ABC, AB = 12 cm and AC = 14

In triangle XYZ,  YZ = 10 cm and XZ = 14

As ABC and XYZ are congruent then the other side of triangle ABC has 10cm.

The perimeter of the given triangle is the sum of the following segments:

Perimeter = PD + DO + OP

based on the given graph, you have that the coordinates of the points PDO are:

P: (1,-6)

D: (4,3)

O: (7,-6)

use the following formula for the distance in between two points:

d = √((x2 - x1)²+(y2 -y1)²)

where (x1,y1) and (x2,y2) are two points on the cordinate system.

For segement PD you have:

PD = √((1-4)²+(-6-3)²) = √(100) = 10

For segemtn DO:

DO = √((4-7)²+(-6-3)²) = √(100) = 10

For segment OP:

OP = √((1-7)²+(-6+6)²) = √36 = 6

then, the perimeter of the triangle is:

perimeter = 10 + 10 + 6 = 26
