Step-by-step explanation:
A customer at a shipping store is planning to send a package and is considering two options. The customer can send a package for $3, plus an additional $2 per pound. The cost, y, can be represented by the equation y = 3 + 2x, where x represents the amount of pounds of the package. 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.
The correct option is :
A package that weighs 7 pounds will cost $17 for both options.
What is an equation ?The declaration that shows that the provided variables exist is a mathematical equation. When describing the scenario in this circumstance, two or more factors are taken into account.
The equation can be used to symbolize the price, y: Y is equal to 3 plus 2 times the weight of the package, x.
Another choice is for the buyer to pay a one-time price of $17, which is represented by the equation y = 17, in order to send the package.
We'll compare the equation as a whole.
In this case,
3 + 2x = 17
Compile similar terms
2x = 17 - 3
2x = 14
x = 14 divided by 2x = 7

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.
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

It is possible for 2 lines to
intersect in such a way
that 3 of the angles
formed have measures 20,
70, and 20.?
Sometimes true,
Never true,
Always true.
Answer:
sometimes true
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°

The amount of ribbon needed to buy for the project in meters is (d) 5.
According to question,
1 centimeter = 0.01 meter
2.54 centimeter = 0.01*2.54
= 0.0254 meters
1 inches = 2.54 centimeters
= 0.0254 meters
Amount of ribbon needed for project = 182 inches
= 182 * 0.0254 meters

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
