Solve the system of linear equations by graphing. y = 3/4x-4 y= -1/2x+11

Answers

Answer 1

Taking into account the definition of a system of linear equations, the solution of the linear equation is (12,5).

System of linear equations

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

This case

In this case, the system of equations to be solved is

y = 3/4x-4

y= -1/2x+11

There are several methods to solve a system of equations, it is decided to solve it using the graphical method. This method consists of representing the graphs associated with the equations of the system to deduce its solution. The solution of the system is the point of intersection between the graphs since the coordinates of said point satisfy both equations.

In this case, graphing both equations, it is obtained that the point of intersection, and therefore the solution, is (12,5).

The graph of the system of equations is attached.

a. How many cubes with an edge length of b. What is the volume, in cubic inches, of inch are needed to build a cube with one cube with an edge length of inch? an edge length of 1 inch?

Answers

The number of cubes of edge length 1/3 is 27 and the volume of the cube is 1 cubic inches

How to determine the number of cubes

From the question, we have the following parameters that can be used in our computation:

Edge length of cube 1 = 1/3 inchEdge length of cube 2 = 1 inch

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube 1 = (1/3 inch)³ = 1/27 cubic inches

Volume of cube 2 = (1 inch)³ = 1 cubic inch

The number of cubes is then calculated as

Number of cubes = Volume of cube 2/Volume of cube 1

This gives

Number of cubes = 1/(1/27)

Number of cubes = 27

The volume of the cubes

Here, we have

Edge length of cube = 1 inch

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube = (1 inch)³ = 1 cubic inch

Step-by-step explanation:

Given points:

(-4, 3)(6, 1)(1, -4)(-3, -5)

To find the equations for each of the lines:

Find the slope of the line by substituting two points on the line into the slope formula.Substitute the found slope and one of the points on the line into the point-slope formula and simplify.

Line #2

Points:

Let (x₁, y₁) = (6, 1)Let (x₂, y₂) = (1, -4)

Find the slope:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-4-1}{1-6}=\dfrac{-5}{-5}=1[/tex]

Substitute the found slope and one of the points into the point-slope formula:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-1=1(x-6)[/tex]

[tex]\implies y=(x-6)+1[/tex]

[tex]\implies y=x-5[/tex]

Line #3

Points:

Let (x₁, y₁) = (1, -4)Let (x₂, y₂) = (-3, -5)

Find the slope:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-5-(-4)}{-3-1}=\dfrac{-1}{-4}=\dfrac{1}{4}[/tex]

Substitute the found slope and one of the points into the point-slope formula:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-(-4)=\dfrac{1}{4}(x-1)[/tex]

[tex]\implies y+4=\dfrac{1}{4}(x-1)[/tex]

[tex]\implies y=\dfrac{1}{4}(x-1)-4[/tex]

Line #4

Points:

Let (x₁, y₁) = (-3, -5)Let (x₂, y₂) = (-4, 3)

Find the slope:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-5)}{-4-(-3)}=\dfrac{8}{-1}=-8[/tex]

Substitute the found slope and one of the points into the point-slope formula:

[tex]\implies y-y_1=m(x-x_1)[/tex]

[tex]\implies y-(-5)=-8(x-(-3))[/tex]

[tex]\implies y+5=-8(x+3)[/tex]

[tex]\implies y=-8(x+3)-5[/tex]

Sugar cookies Cookies with no frosting Chocolate chip cookies with frosting Sugar cookies with no frosting

Answers

The category which has the greatest joint frequency is sugar cookies with a frequency of frosting and no frosting as 56 and 120 and a joint frequency of 176

Which category has the highest joint frequency?

Frosting No frosting Total

sugar cookies 56 120 176

Chocolate cookie 66 70 136

Red velvet 38 50 88

Total 160 240 400

Chocolate cookies with frosting = Total chocolate cookies - chocolate cookies with no frosting

= 136 - 70

= 66

Red velvet cookies with frosting = Total cookies with frosting - (Chocolate cookies with frosting + sugar cookies with frosting)

= 160 - (56 + 66)

= 160 - 122

= 38

Total red velvet cookies = Red velvet cookies with frosting + Red velvet cookies with no frosting

= 50 + 38

= 88

Total cookies with no frosting = Total cookies - Total cookies with frosting

= 400 - 160

= 240

Total sugar cookies with no frosting = Total cookies with no frosting - (chocolate cookies with no frosting + Red velvet cookies with no frosting)

= 240 - (70 + 50)

= 240 - 120

= 120

Total sugar cookies = Total sugar cookies with no frosting + Total sugar cookies with frosting

= 120 + 56

= 176

In conclusion, the highest joint frequency is sugar cookies.

The total time required in months is 108 months.

What is simple interest?

Simple interest is defined as the amount of interest paid on a specific principal, an amount at a specific interest rate. It is given by

I = Prt

where, I = simple interest, P = Principal, r = rate of interest, t = time taken

Given, P = $100

I = $135

r = 0.15

t = ?

So, simple interest is given by:

I = Prt

or, 135 = 100*0.15*t

or, 135 = 15*t

or, t = (135/15) = 9 years = 9*12 = 108 months

The equation of line is y + 2x +7 =0 for the points (-5,3) and (0,-7).

What is equation of line?

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given points are (-5, 3) and (0, -7).

To find the equation of line, use formula,

y - y₁ = m(x - x₁) where m = (y₂-y₁)/(x₂-x₁),

y - 3 = (-7 - 3)/(0-(-5)) (x - (-5))

y - 3 = -10 / 5 (x + 5)

y - 3 = -2 (x + 5)

y + 2x +7 =0

What is a fraction?

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

Chindi puts 2(3/5) kg of bird seed in his large feed.

This is 1(3/10) times as much bird seed as he puts in his smaller feeder.

The total amount is represented by 1.

Now,

1(3/10) = 2(3/5) kg

13/10 = 13/5 kg

Multiply both sides by 10/13

1 = 10/13 x 13/5 kg

1 = 2 kg

This means the total amount of seeds in the smaller feeder is 2 kg.

Thus,

The total amount in the smaller feeder is 2 kg.

In Silvergrove, the library is due south of the courthouse and due west of the community swimming pool. If the distance between the library and the courthouse is 9 kilometers and the distance between the courthouse and the city pool is 10 kilometers, how far is the library from the community pool? If necessary, round to the nearest tenth.

Answers

The distance of the library from the community pool is given as 4.4 km

How to solve for the distance

We have to solve this problem with the use of the Pythagoras theorem.

The formula is given as

a² = b² + c²

The total distance flown would be represented by a = 10 kilometer

the distance for the courthouse would be given as 9 kilometers

When we put these values in the formula we would have

10² = a² + 9²

100 = a² + 81

a² = 100 - 81

a² = 19

a = √19

a = 4.4 km

Hence the calculated distance is given a 4.4 km from the library to pool.

What is a function?

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).

if f(x) = 2x, then f(x-4) = 2(x-4)

g(x) = f(x-4) + 5

substitute f(x-4) into g(x)

g(x) = 2(x-4) + 5

Think About the Process You have 30 quarters. You find 20% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping. Calculate, in dollars, the amount of money you have left.

Answers

Answer: $4.5 left.

Step-by-step explanation:

You have 30 quarters, and find 20% more. To convert percentages to decimals for calculations, simply move the decimal two spaces to the left.

20% is 20. ---> 2.0 ---> .20

30 * 0.2 = 6. Now add 6 (found) to 30 (original) to get the total.

30+6 = 36 total quarters.

You spend 50% of the quarters, 36 * 0.5 = 18.

This means you have 18 quarters left (or you spent 18).

18 quarters, each quarter is worth 0.25 dollars, so multiply the number left by how much each is worth.

18 * 0.25 = $4.5.

$4.50 is the amount left
