The bill accumulates to $10 plus a 10% tax fee

If they split the bill and and tax evenly

The amount each person will pay can be calculated as follows

21 × (1+10/100) /3

= 21 × (1+0.1)/3

= 21 × 1.1/3

population at 1992 = 3590

Population after Seven years (1999) = 4500

Given two points (t1, P1) and (t2, P2), the slope of the line m can be found.

p1 = (1992, 3590) and p2 = (1999, 4500)

m= ΔP/Δt

m= ((4500-3590))/((1999-1992))

m = 910/7

m=130 is the slope

The linear population function P(t) is

P(t)=130t + P0

Find the Y-Intercept P0

The population function P(t) is measured since the year 1990, year zero. The first moose population was measured in 1992, one year later. This provides an initial condition P (1) = 4500.

P (1) =130 (1) + P0 = 4500

P0 = 4370

P(t)=20t+4630

The moose population P(t) changes linearly year after year. The population function P(t) is measured in terms of t years since 1990.

t= 1990, P (0) =4370

t =1992, P (1) =130 (1) + 4370 = 4500 matches data

t=1999, P (2) = 130(2) + 4370 = 4630

Now, To find the correct option that is equivalent to this equation, we can begin by narrowing down the given options.

Since, The slope contains a negative number, that's mean the second point must have a lower y value than the first x value.

Hence, By using this criteria, we can eliminate the first and the third option.

Now, we can check the second and fourth option as;

We can test using by putting in values.

Let's plug in the point values to check whether they work:

Hence, For option 2:

y = -5x + 4

-24 = -5(4) + 4

-24 = -20 + 4

-24 ≠ -16

And, For option 4:

y = -5x + 4

-16 = -5(4) + 4

-16 = -20 + 4

-16 = -16

Therefore, The correct  option is option (d).

The complete question is this;

Which line has an equation of y= -5x+4 in slope intercept form?

A line passing through the points -

a) (1,9) & (3,19)

The ratio of malts to the total ice creams is 3:10 .

Ratio is defined as the fraction which defines the relationship between two quantities .

Ratio is denoted by a:b such that it can also be written as a/b where a and b are co-prime. Ratio can also be denoted as a decimal but mostly it is represented as fraction in its lowest terms

Now the given ice cream shop has 14 shakes that are sold for every 6 malts.

Hence when 14 shakes are sold total number of ice cream sold is

14+6 = 20 .

Now we have to find the ratio of the malts to the total number of ice creams

∴ malts : ice creams = 6 : 20

Reducing to lowest terms we get :

ratio = 3:10

Hence the ratio of malts to total ice cream is 3:10

The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.

It is given that:
Scott is 6 feet tall and casts a shadow that is 8 feet long. a nearby tree casts a show that is x+5 feet long

By using scale factor:

Let x be the height of the tree

x/6 = = (x + 5)/8

8x = 6(x + 5)

8x = 6x + 30

The slope of the line whose data represents a linear function is  m = -1/4.

Slope of an straight line is denoted by m and is the measure of rate of change of 'y' with respect to 'x'. Mathematically -

m = tan(θ) = Δy/Δx

Given is a table representing a linear function. From the question, we can write -

X →    6      8     13      14

Y →  -16   -24   -44    -48

We can find the slope of this line using the formula -

m =  Δy/Δx

m =  (y₂ - y₁) / (x₂ - x₁)

Take any two coordinates from the table -

(x₁,  y₁) → (6, -16)

(x₂, y₂) → (8, -24)

Substitute the values in the formula -

m = (8 - 6)/(-24 + 16)

m = - 2/8

m = -1/4

Answer:

[tex]y = -\dfrac{7}{3}x +5[/tex]

Step-by-step explanation:

The general equation of a line in slope-intercept form is

y = mx + b

where m = slope and b = y-intercept is rise over run

[tex]m = \dfrac {(y_{2} - y_{1})} {(x_{2} - x_{1})}[/tex]

where (x₁, y₁) and (x₂, y₂) are any two points on the line

For the line passing through (-6, 19) and (3, -2) , the slope

[tex]m = \dfrac{-2 - 19}{3 - (-6)}\\\\[/tex]

[tex]\\\\m= \dfrac{-21}{9}[/tex]

[tex]m = -\dfrac{7}{3}[/tex]

So slope-intercept form is
[tex]y = -\dfrac{7}{3}x +b\\\\[/tex]

To compute y-intercept, b,  plug in any of the two points into the above equation and solve for b

Let's choose point (3, -2)

Plugging x = 3 and y = -2 gives

[tex]-2 = -\dfrac{7}{3}\cdot 3 +b\\\\\\\\-2 = -7 + b\\\\[/tex]

So equation of line is
[tex]y = -\dfrac{7}{3}x +5[/tex]

The directed line segment for all the given transformations to match the transformed line segment from translation 1 to translation 4.

In this question, the translations are defined by a line segment.

Such that in each translation, we can easily find the segment PQ (the measure and the direction).

And all the points in the Polygon P will be connected by that same segment PQ to the equivalent point in the Polygon Q. (where you only move the segment to the correct location, but the length and direction remains constant)

Thus, to find the line segment for each transformation, you need to correctly measure the length of the segment PQ, and also the direction (that can be defined by an angle).

With the above, we can find the directed line segment for all the given transformations to match the transformed line segment from translation 1 to translation 4.
