Choose the best graph that represents the linear equation:
-x = 2y + 1
Answers
The line slants downward from left to right, indicating that as x increases, y decreases.
The given linear equation is -x = 2y + 1. To represent this equation graphically, we need to rearrange it into the slope-intercept form, which is y = mx + b, where m represents the slope and b represents the y-intercept.Rearranging the given equation, we get:2y = -x - 1
Dividing both sides by 2:y = (-1/2)x - 1/2
The slope of the line is -1/2, which means that for every unit increase in x, y decreases by 1/2 unit. The y-intercept is -1/2, indicating that the line intersects the y-axis at (0, -1/2).
Based on this information, the best graph that represents the linear equation y = (-1/2)x - 1/2 is a straight line with a negative slope of -1/2, starting at the point (0, -1/2) and extending infinitely in both directions.

Answers
Answer:
6 inches
Explanation:
On the square pattern, one side of the square starts at point (5,-4) and ends at point (5,2).
To determine the length of a side of the square, find the distance between the endpoints.
From the endpoints: (5, -4) and (5,2)
The x-coordinates are the same, therefore, the distance between the endpoints is:
\(|2-(-4)|=|2+4|=6\text{ units}\)If each unit on the pattern is one inch, the length of a side of the square is 6 inches.

There were 985 bagels made at the bakery. If 7 bagels were packed into each box, how many boxes were made? The remaining bagels were given to the baker. How many bagels were given to the baker?
Answers
There will be a total of 140 boxes, and the baker will get 5 bagels.
how many boxes were made?
We know that a total of 985 bagels where made at the bakery. 7 bagels were packed into each box, so the total number of boxes needed is given by the quotient between the total number of bagels and the number of bagels in each box, this gives:
q = 985/7 = 140 + 5/7
So we can have 140 complete boxes, and a remainder of 5 bagels.
We know that the remaining bagels were given to the baker, then the baker received 5 bagels.

An actor bought a pearl, diamond, and ruby necklace for his famous wife for $54,000. In 2011 this necklace was auctioned for $11,379,600. The auction price was what percent of the original purchase price?
Answers
This necklace sold at auction for $11,379,600 in 2011. The percentage of the initial purchase price was represented by the auction price is 2.1%.
Given that,
For $54,000, an actor purchased a pearl, diamond, and ruby necklace for his well-known wife. This necklace sold at auction for $11,379,600 in 2011.
We have to find what percentage of the initial purchase price was represented by the auction price.
Let us take the percentage as x%.
Necklace sold at auction=the percentage multiplied by the actual price
We get,
$11,379,600 =x%($54,000)
x%=$11,379,600/$54,000
x%=2.1%
Therefore, the percentage of the initial purchase price was represented by the auction price is 2.1%.

A circle has a diameter of 4.5 cm. A larger circle has a diameter of 24
cm. What is the approximate difference in the circumferences of the
two circles?
A 19.5 cm
B. 28.5 cm
C. 61 cm
D. 90 cm
Answers
The approximate difference in the circumferences of the two circles is: C. 61 cm.
How to calculate the circumference of a circle?Mathematically, the circumference of a circle can be calculated by using this mathematical expression:
C = 2πr or C = πD
Where:
C represents the circumference of a circle.D represents the diameter of a circle.r represents the radius of a circle.Substituting the given parameters into the circumference of a circle formula, the circumference of the small circle is;
Circumference of circle, C = πD
Circumference of circle, C = 3.14 × 4.5
Circumference of circle, C = 14.13 cm.
For the larger circle, we have:
Circumference of circle, C = 3.14 × 24
Circumference of circle, C = 75.36 cm.
Difference = 75.36 cm - 14.13 cm.
Difference = 61.23 ≈ 61 cm.

height of the prism is 13 cm. Find the
volume of the prism.
Answers
Answer:
585\(cm^{3}\)
Step-by-step explanation:
45 x 13 = 585
Let me explain...
we don't know the length and the width but it is telling us that there is an area of 45 centimeters. Meaning the Length x Width is equal to the area. so there wasn't no need to solve for length and width.
So that's why we only had to multiply the 45 (Length x width) and the height which is 13.
Final Answer: 585\(cm^{3}\)

Expression in factored form
a² - 36 = (a + 6)(a - 6)
49 - 25b² = (7 - 5b)(7 + 5b)
c² + 9 = Not possible (sum of squares)
10081 - 16d² = (101 - 4d)(101 + 4d)
64 + 121b² = Not possible (sum of squares)
Let's factorize each expression:
a² - 36:
This expression is a difference of squares, as it can be written as (a + 6)(a - 6). Therefore, the factored form is (a + 6)(a - 6).
49 - 25b²:
This expression is also a difference of squares. It can be factored as (7 - 5b)(7 + 5b).
c² + 9:
This expression is not factorable because it is a sum of squares. The factored form is not possible.
10081 - 16d²:
This expression is a difference of squares. It can be factored as (101 - 4d)(101 + 4d).
64 + 121b²:
This expression is not factorable because it is a sum of squares. The factored form is not possible.
To summarize:
a² - 36 = (a + 6)(a - 6)
49 - 25b² = (7 - 5b)(7 + 5b)
c² + 9 = Not possible (sum of squares)

The surface area of a similar cylinder with a diameter 3 cm is 8.4375π cm².
What are similar figures?If two figures have the same shape, they are said to be comparable. In more formal terms, two figures are said to be similar if their respective angles are congruent and their corresponding side length ratios are identical.
Given a cylinder with a diameter 8 cm and a surface area 60π cm²
let the radius be R = dia/2 = 8/2= 4 cm
and let the height be H
total surface area of cylinder = 2πR(H + R)
60π = 2π(4)(4 + H)
4 + H = 60/8
H = 7.5 - 4
h = 3.5 cm
and a cylinder is similar to given cylinder,
let radius be r and height be h
given dia = 3 cm
r = 3/2 = 1.5 cm
since both cylinders are similar so the ratio of their height to radius is equal,
R/H = r/h
h = Hr/R
h = (3.5)(1.5)/4
h = 1.3125 cm
total surface area of cylinder = 2πr(h + r)
total surface area of cylinder = 2π(1.5)(1.5 + 1.3125)
the total surface area of the cylinder = 8.4375π cm²
Hence the area of a cylinder is 8.4375π cm².

Which graph represents function g if g(x)=f(2x)
Answers
The new function g(x) which is equal to f(2x) will be stretched or compressed by the factor 2.
What is a function?It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function f(x) shown in the coordinate plane.
The function g(x) = f(2x)
As we can see in the new function g(x) it is the transformation of the f(x).
Transformation is applied as below:
x → 2x (x is replaced by the twice of it)
= f(x)
= f(2x)
= g(x)
When the function is multiplied by a positive number it will be stretched or compressed according to that factor vertically and in the given function the factor is 2 which means the g(x) will be stretched or compressed according to that factor.
Thus, the new function g(x) which is equal to f(2x) will be stretched or compressed by the factor 2.
