Answer: Slope

Step-by-step explanation:

Slope is rise over run. It can be calculated by dividing the change in y (rise) over the change in x (run).

The slope of a non vertical line passing through two points is the ratio of the rise to the run.

What is slope of a line?

The slope of a line is a measurement of its steepness and direction.The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points along a line.

1. Slope of Parallel Lines :

A set of parallel lines always has the same inclination angle. Assume we possess two parallel lines l1 and l2 in the reference plane, inclined at angles θ1  and θ2 with the x-axis, respectively, such that the, θ2 = θ1.

m1 = m2

Therefore, the slopes of the two given parallel lines are equal.

2. Slope of Perpendicular Lines :

A pair of perpendicular lines always form a 90° angle. Imagine we have two perpendicular lines l2 and l1 in the coordinate plane, inclined at angles θ1 and θ2 with the x-axis, respectively, so that the provided angles follow the external angle theorem, θ2 =  θ1 + 90°

m₁ = tan θ₁

m₂ = tan (θ₁ + 90º) = - cot θ₁

m₁ × m₂ = -1

Therefore, the product of slopes of two given perpendicular lines is equal to -1

Hence , The slope of a non vertical line passing through two points is the ratio of the rise to the run.

Answer:

Step-by-step explanation:

Mrs. Chipps buys 30 c + 50 r = $95

Mr. Meehan buys 40 c + 40 r = $116    x (-1.25) to eliminate r

                             30 c + 50 r = $ 95

                            -50 c - 50 r  = $-145

                            -20 c             =  -50

                                               c = 50 / 20

                                               c = $2.5

substitute c = 2.5 into eq. 1

30 c + 50 r = $95

30 (2.5) + 50 r = 95

75 + 50 r = 95

50 r = 95 - 75

r = 20 / 50

r = 0.40

therefore, the individual costs of the compasses and rulers are:

compass = $ 2.50 each

ruler        = $ 0.40 each

Step-by-step explanation:

In SAS similarity theorem if two sides of one triangle are proportional to two sides of another triangle and angle between them are congruent then the triangle are similar.

Answer:

x = 10

Step-by-step explanation:

Okay the two sides are going to equal the same measure soo...

4x + 9 = 11x - 61 (Subtract 4x on both sides)

9 = 7x - 61 ( add 61 on both sides)

70 = 7x (divide both sides by 7)

10 = x

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

In triangles ΔJMK and ΔLMK, then we have

∠JMK = ∠LMK = 90°          (Right angle)

∠JKM = ∠LKM                    (Given)

KM = KM                             (Common side)

The triangles ΔJMK and ΔLMK are congruent with each other. Then the sides JK and KL will be equal. Then the value of 'x' will be given as,

KL = JK

11x - 61 = 4x + 9

11x - 4x = 61 + 9

7x = 70

x = 70 / 7

x = 10

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.

Answer:X=3

y= -4

Step-by-step explanation:

If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.

so solving for x, 4x=12--> x=3, since y=0 in this scenario.

Solving for y, x=0, so -3y=12--> y=(-4)

9514 1404 393

Answer:

  see below for a table

Step-by-step explanation:

You can easily identify intercept points by solving for one variable when the other is zero.

x-intercept (y=0)

  4x = 12

  x = 12/4 = 3

y-intercept (x=0)

  -3y = 12

  y = 12/-3 = -4

So, the coordinate pairs of these points are ...

  (3, 0) and (0, -4)

__

If you solve for y, you get ...

  -3y = 12 -4x

  y = (4/3)x -4 . . . . . divide by -3

This suggests that x being a multiple of 3 will be useful for finding integer values of y.

We already have points for x=0 and x=3. We can add points for x=6 and x=-3.

  y = 4/3(6) -4 = 4

  y = 4/3(-3) -4 = -8

So, the additional points are ...

  (6, 4) and (-3, -8)

Answer:

X intercept = 1/2

(x, y) = (1/2, 0)

Step-by-step explanation:

In order to find the x intercept, plug y = 0

y = - 4x + 2

Plug y = 0

0 = - 4x + 2

4x = 2

x = 2/4

x = 1/2

(x, y) = (1/2, 0)

5:14

Step-by-step explanation:

The ratio of adults to children using the form 1:n would look like this:

number of adults : number of children

So:

5 adults : 14 children = 5:14

Answer:

1 : 2.8

Step-by-step explanation:

in such a case what the question is asking you to is to compare the numbers and simplify them with the left hand number.

ratio of adult to children

write it as 5:14

put the 1 :n underneath

5  :  14   what we want to find is the n. among the 2 sides one is complete                      

1   :   n      only whole numbers. to get n look at the complete side . if

                    5:1      14=14 x 1 /5(cross multiplication). or you can

divide both sides by the left hand number(5)

5   and   14   =   1 :  2.8

5              5

the n is what we were trying to find and compare it to 1

this means for every 1 adult there are 2.8 children

Answer:

£15.6

Step-by-step explanation:

Method 1:

You are trying to find 30% of £52.

Therefore:

[tex]\frac{30}{100} * 52 = \frac{30 * 52}{100}[/tex]

If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.

So, the answer is £15.6.

Method 2:

You can solve 30% of £52 by using an algebra equation.

By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.

Now, in order to write the equation, you will have to include 0.3 and 52.

The equation is:

0.3 * 52 = x

Once you multiply, you will find that the answer is £15.6.

Population = All adults.

Step-by-step explanation:

In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.

On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.
