Inequality

Step-by-step explanation:

An expression is a mathematical phrase that contains numbers, variables, or both. Expressions never have an equal sign. An equation is a mathematical sentence that says two expressions are equal.

The point (1, 60). on the graph how's the speed that the car travels.

It should be noted that car traveled at a constant speed. The distance traveled is 210 miles and the time to travel is 3.5 hours.

Therefore, it should be noted that the point (3.5, 120) shows the distance.

The slope of the like which is the speed will be:

= Distance / Time

= 210 / 3.5

= 60 mph

Therefore, it should be noted that the point B(1, 60) lies on the graph.

It is to be noted that the height of the bread is 5 centimeters. The hint given is in the information about the surface area. See the explanation below.

In this case, the surface area of bread is the total sum of the area of the base and perimeter. The surface area of the bread is given below.

That is:

A = 2 x b + p x H,

Where b is the area of the base,  p is the perimeter of the base and h is the height.

Recall that it is stated that 50% of the surface area of the bread is the crust.

The implication is that the surface area of both sides of the base is equivalent to the surface area of its perimeter.

That is:

2 x b = p x h

We can compute the perimeter of the bread as:

P = 4 x length
p = 4 x 10
p = 40cm

The area of the base is:

b = 10 x 10
b = 100cm²

Substituting the values in the above formula,
2 x 100 = 40 x h
200 = 40h
h = 200/40

h= 5cm.

Hence the height of the bread is 5cm.

Based on the dilation, the scale factor of dilation of the point is 1/3

Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.

From the question, we have the following parameters

Dilation rule: Do,k

Point = (9, 6)

Image = (3, 2)

As a general rule of dilation, the following are the properties of a scaled copy of another figure

Using the above as a guide, the scaled factor is calculated as

Scaled factor = Image/Poins

This gives

Scaled factor, k = (3, 2)/(9, 6)

This gives

Scaled factor, k = 1/3

The inequality which represents the possible values for the number of peaches and mangos purchased will be;

⇒ $0.75p + $1.75m = $15

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Avni and her children went into a grocery store and will buy peaches and mangos.

Each peach costs $0.75 and each mango costs $1.75.

And, Avni has a total of $15 to spend on peaches and mangos.

Now,

Let number of peaches purchased = p

And, Number of Mangos purchased = m

Since, Each peach costs $0.75.

Hence, Total cost of peaches purchased = $0.75p

And, Each mango costs $1.75.

Hence, Total cost of mangos purchased = $1.75m

Since, Avani has a total of $15 to spend on peaches and mangos.

So, An inequality that would represent the possible values of peaches and mangos will be;

⇒ $0.75p + $1.75m = $15

Thus, The inequality which represents the possible values for the number of peaches and mangos purchased will be;

⇒ $0.75p + $1.75m = $15

The price of one adult ticket is $5 and one student ticket is $14

Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.

Given that : first day of ticket sales the school sold 14 adult tickets and 5 student tickets for a total of $140. The school took in $190 on the second day by selling 10 adult tickets and 10 student tickets.

Let the price for adult ticket x and for student ticket y

we have ,

14x + 5y =140.....(i)

10x  + 10y = 190....(ii)

10 x + 10y = 190

x + y = 19

y = 19-x .....(iii)

put the value of y in equation i

14x + 5(19-x) = 140

14x + 95 - 5x = 140

[tex]\textsf{Slope-intercept form}: \quad y=-\dfrac{4}{3}x+\dfrac{5}{3}[/tex]

[tex]\textsf{Standard form}: \quad 4x+3y=5[/tex]

Step-by-step explanation:

Given linear equation:

[tex]y-11=-\dfrac{4}{3}(x+7)[/tex]

The given linear equation is point-slope form.

[tex]\boxed{\begin{minipage}{3.7cm}\underline{Slope-intercept form}\\\\$y=mx+b$\\\\where $m$ is the slope\\ and $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

To write the equation in slope-intercept form, isolate y:

[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]

[tex]\implies y-11=-\dfrac{4}{3}x-\dfrac{28}{3}[/tex]

[tex]\implies y-11+11=-\dfrac{4}{3}x-\dfrac{28}{3}+11[/tex]

[tex]\implies y=-\dfrac{4}{3}x+\dfrac{5}{3}[/tex]

[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Standard form}\\\\$Ax+By=C$\\\\where $A, B$ and $C$ are constants and $A$ must be positive.\\\end{minipage}}[/tex]

To write the equation in standard form, eliminate the fraction, bring the terms in x and y to the left of the equation, and the constants to the right:

[tex]\implies y-11=-\dfrac{4}{3}(x+7)[/tex]

[tex]\implies (y-11) \cdot 3=-\dfrac{4}{3}(x+7) \cdot 3[/tex]

[tex]\implies 3y-33=-4(x+7)[/tex]

[tex]\implies 3y-33=-4x-28[/tex]

[tex]\implies 3y-33+4x=-4x-28+4x[/tex]

[tex]\implies 3y-33+4x=-28[/tex]

[tex]\implies 3y-33+4x+33=-28+33[/tex]

Something is a function if the x value is not repeated. The y value can be repeated however.

Value of the function [ f(x+ h) - f(x) ] /h in simplest form when f(x) = -2x -1 is equal to -2.

As given,

Given function:

f(x) = -2x -1

$620 ram deduct as a business expense

Answer:

no 110 tax cuts and job act took away tickets and entertainments

Step-by-step explanation:

For every mile the car is driven, the cost increases by 0.52 units.

Consider a line that passes through the origin at a distance 'a' from the Y-axis and has a slope of m. In this situation, the distance an is the definition of the line's y-intercept. At this moment, the line will cross the y-axis (0, a). The equation for the line will then be y = mx + a. The same goes for a line that crosses the X-axis at a position b from the origin and has a slope of m. (b,0). The distance b is the line's x-intercept. The equation for the line will be y = m* (x-b)

Given, the equation that relates cost of renting and miles driven is
y = 0.52 x + 186
Therefore, for a car travelling one mile, cost is y₁ = 0.52*1 + 186 = 186.52
For a car travelling two miles, cost is y₂ = (0.52*2) + 186 = 187.04
Thus, for every next mile the cost increases by = y₂ - y₁ = 187.04 - 186.52 = 0.52 units
