The linear function (B) [f(x) = -1/2x+ 1] represents the given graph with coordinates (0, 1) and (2, 0).
What are linear functions?The term "linear function" in mathematics applies to two different but related ideas: A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields.The graph of a linear function is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively.So, the linear function that represents the graph:
We need to plot all the functions on the graph to get the correct linear function.After plotting, we came to the conclusion that function [f(x) = -1/2x+ 1] represents the same graph as shown in the figure.Therefore, the linear function (B) [f(x) = -1/2x+ 1] represents the given graph with coordinates (0, 1) and (2, 0).

Tess builds a sandbox in the shape of a regular hexagon in which all the sides are 40 inches long. She then takes a photo of the sandbox and prints the photo. In the photo, the sides of the hexagon are each 4 inches long. Identify the scale factor that was used to create the printed photo of the sandbox. Express your answer as a decimal.
Answers
A scale factor of 0.1 was used to create the printed photo of the sandbox
How to find the scale factor used for the printed photo of the sandbox?A scale factor is the size by which a shape is enlarged or reduced. It is used in increasing or reducing the size of a 2D shape, such as circle, triangle, square, rectangle, hexagon, etc.
Given that: Tess builds a sandbox in the shape of a regular hexagon in which all the sides are 40 inches long, and in the photo, the sides of the hexagon are each 4 inches long
The scale factor will be:
4/40 = 1/10 = 0.1
This means the sandbox has been reduced by 10 times the original size
Therefore, the scale factor that was used to create the printed photo of the sandbox is 0.1

ANSWER and EXPLANATION
We want to order the functions from widest to narrowest:
[tex]\begin{gathered} y=3x^2 \\ y=2x^2 \\ y=4x^2 \end{gathered}[/tex]To do this, we have to plot the graphs of the functions by using a table of values.
Let us find the values of the functions for values of x = -2, 0, 2
For the first function:
[tex]\begin{gathered} y=3x^2 \\ \Rightarrow x=-2: \\ y=3(-2)^2=3*4 \\ y=12 \\ \Rightarrow x=0: \\ y=3(0)^2=3*0 \\ y=0 \\ \Rightarrow x=2: \\ y=3(2)^2=3*4 \\ y=12 \end{gathered}[/tex]Hence, its table is:
For the second function:
[tex]\begin{gathered} y=2x^2 \\ \Rightarrow x=-2: \\ y=2(-2)^2=2*4 \\ y=8 \\ \Rightarrow x=0: \\ y=2(0)^2=2*0 \\ y=0 \\ \Rightarrow x=2: \\ y=2(2)^2=2*4 \\ y=8 \end{gathered}[/tex]Hence, its table is:
For the third function:
[tex]\begin{gathered} y=4x^2 \\ \Rightarrow x=-2: \\ y=4\left(-2\right)^2=4*4 \\ y=16 \\ \Rightarrow x=0: \\ y=4(0)^2=4*0 \\ y=0 \\ \Rightarrow x=2: \\ y=4(2)^2=4*4 \\ y=16 \end{gathered}[/tex]Hence, its table is:
Now, let us plot the graphs of the functions:
Therefore, from the graph, we see that the order of the functions from widest to narrowest is:

What is a function?
A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.
Given f(x)= -4x-2
g(x)=2x²+4x-5
For (f-g)(x) = -4x-2+2x²+4x-5
=2x²-9
(f-g)(x) = 2x²-9
Hence, The addition of the given two functions will be (f · g)(x) = 2x²-9

Answers
The total volume of the 40 sphere shaped water balloons is 46032.38 cubic cm.
Radius of 1 sphere = 6.5 cm
We know that the volume of the sphere is given by 4/3 π r³

Now we will find the volume : 4/3 ×22/7×6.5³ = 1150.81 cubic cm.
Volume of 40 such spheres = 40 × 1150.81 = 46032.38 cubic cm.

A cyclist travels north along a road at a constant speed of 18 miles per hour. At 1:00 P.M., a runner is 46 miles away, running south along the same road at a constant speed. They pass each other at 3:00 P.M.. What is the speed of the runner?
Answers
By forming and solving equations, we know that the speed of the runner is 4 miles per hour.
What are equations?The equals sign is a symbol used in mathematical formulas to denote the equality of two expressions. An equation is a mathematical statement that contains the symbol "equal to" between two expressions with identical values. As in 3x + 5 = 15, for example. There are many different types of equations, including linear, quadratic, cubic, and others. The three primary forms of linear equations are point-slope, standard, and slope-intercept.So, we need to form an equation to get the speed of the runner:
2 × (18 + x) = 44'x' is the speed of the runner. Now, solve for x as follows:
2 × (18 + x) = 4418 + x = 44/218+x = 22x = 22 - 18x = 4 miles per bourTherefore, by forming and solving equations, we know that the speed of the runner is 4 miles per hour.

Sometimes true,
Never true,

Answers
Answer:

Step-by-step explanation:
Given, two straight lines intersect each other in such a way that one of the angles formed measure 90°.
We know that, lines which intersect to form a right angle are known as perpendicular lines
In the above figure , AB is perpendicular to CD
Considering ∠AOC=90°
Now,
∠AOC+∠AOD=180° [Linear pair]
90°+∠AOD=180°
∠AOD=90°
Similarly,
∠AOC+∠BOC=180° and ∠BOD+∠AOD=180° [Both making linear pair]
So, we get ∠BOC=90° and ∠BOD=90°
Hence, ∠AOC=∠AOD=∠BOC=∠BOD=90°

Kim and steve went to dinner. kim has a coupon for a 25% discount of all meals not including tax and tip. if the original price of the meal was $75, how much money will they save?
Answers
The amount Kim and Steve will save is $18.75.
Define discountDiscount refers to a price decrease on items or services that merchants are willing to sell to customers at a marked-up price. Usually, this portion of the rebate is provided to boost sales or get rid of unsold inventory. The list price, also known as the marked price, is the cost of a product as stated by the manufacturer or the seller, and it does not include any discounts. After any reductions or discounts to the list price, the selling price is the actual price at which an item is sold. Discounts are frequently referred to as "off" or "reductions," among other names. It should be noted that the discounted price is always based on the marked price (also known as the list price or original price) of the product.
Given, the discount they have is of 25%.
Original price of the meal is $75.
Now find the discount on the original price.
Discount = Discount (%) * Original Price
= [tex]\frac{25}{100} *75[/tex]
= 0.25*75
= $18.75
Therefore, they saved an amount of $18.75.

Another option is that the customer can pay a one-time fee of $17 to send the box, represented by the equation y = 17.
Based on the graph of the system of equations, when will the cost of the two shipping options be the same?
A package that weighs 10 pounds will cost $17 for both options.
A package that weighs 7 pounds will cost $17 for both options.
A package that weighs 17 pounds will cost $31 for both options.
A package that weighs 17pounds will cost $37 for both options.
