Step-by-step explanation:

The equation illustrates the given information is 5x+4y=200

Cement= a bag x kg

Gravel =a bag of y kg

An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

and the total is 200kg

Therefore we get the equation is

5x+4y=200

Therefore the equation illustrates the given information is 5x+4y=200.

Answer:

y=1

Step-by-step explanation:

you can use those points to find the slope

use the equation [tex]\frac{y_{1} - y_{2}}{x_{1}-x_{2}}[/tex] then plug in the numbers

so (1-1)/(-8-7) = 0/15 so the slope is zero meaning it is a horizontal line which we can tell logically because the y coordinates of both points are 1.

so if you plug those numbers into the formula y=mx+b where m is slope and b is the y intercept then

you get y=0*x+1

then 0*x is just zero and it goes away so the equation for this line is y=1

Hope this helps! :)

The equation of the line that passes through the points (-8, 1) and (7, 1) will be y = 1.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

The two points are given below.

(-8, 1) and (7, 1)

Then the equation of the line that passes through the points (-8, 1) and (7, 1) will be given as,

(y - 1) = [(1 - 1) / (7 + 8)](x - 7)

y - 1 = 0

y = 1

The equation of the line that passes through the points (-8, 1) and (7, 1) will be y = 1.

There are 720 different ways.

Step-by-step explanation:

6! = 720

(1*2*3*4*5*6)

The number of unique ways to arrange the questions will be 36.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Karla who is creating a survey with 6 questions. She suspects that the order of the questions may influence the responses, so she wants to create multiple versions of the survey with the same 6 questions in different orders.

Assume that the she has to arrange the [x] questions. Then the number of unique ways are there to arrange the questions will be x². For [x] = 6, we can write the number of ways to be (6 x 6) = 36.

Therefore, the number of unique ways to arrange the questions will be 36.

Step-by-step explanation:

The area of the garden is the amount of space on the garden.

The dimensions of the garden is given as:

15 meters by 20 meters

Let the width of the pedestrian pathway be x.

So, the area of the total garden is:

[tex]Area=(x + 15)(x + 20)[/tex]

In (a), we have:

[tex]Area=(x + 15)(x + 20)[/tex]

The total area is given as: 336.

So, we have:

[tex](x + 15)(x + 20) = 336[/tex]

Expand

[tex]x^2 + 35x + 300 = 336[/tex]

Collect like terms

[tex]x^2 + 35x + 300 - 336 = 0[/tex]

Evaluate

[tex]x^2 + 35x - 36 = 0[/tex]

Expand

[tex]x^2 + 36x -x - 36 = 0[/tex]

Factorize

[tex]x(x + 36) -1(x +36) = 0[/tex]

Factor out x + 36

[tex](x + 36)(x -1) = 0[/tex]

Solve for x

x = -36 or x =1

The width cannot be negative.

Hence, the width of the pathway is 1 meter

Equation in slope intercept form

[tex]\\ \rm\rightarrowtail y-4=-7(x)[/tex]

[tex]\\ \rm\rightarrowtail y=-7x+4[/tex]

Answer:

[tex]y=-7x+4[/tex]

Step-by-step explanation:

Formulae

Slope-intercept form of a linear function: [tex]y = mx + b[/tex]

(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)

Point-slope form of a linear function:  [tex]y-y_1=m(x-x_1)[/tex]

(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex]  is a point on the line)

Slope formula

[tex]\textsf{slope}=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points on the line)

Solution

Choose 2 points on the line:

Find the slope using the slope formula:

[tex]\implies \textsf{slope}=\dfrac{-3-4}{1-0}=-7[/tex]

Substitute found value for [tex]m[/tex] and point (0, 4) into the point-slope formula:

[tex]\implies y-4=-7(x-0)[/tex]

[tex]\implies y=-7x+4[/tex]
