Answer:
Distance from point A(0,5) to y = -3 x - 5 is √10 units units.
Step-by-step explanation:
Here, the given line equation is y = -3x -5
Also, the point A (0,5) is the given point.
Now, a distance of a point (m,n) from a line Ax + By + c = 0 is given as:
[tex]d = \frac{\mid Am +bn+c \mid}{\sqrt{A^2 + B^2} }[/tex]
Here, the equation is y = -3 x -5
⇒ 3 x + y + 5 = 0 , here A = 3, B = 1
Now, the value of line equation at (0,5) is 3(0) + 5 + 5 = 10
So, from the given distance formula, we get:
[tex]d = \frac{\mid Am +bn+c \mid}{\sqrt{A^2 + B^2} } = d = \frac{10}{\sqrt{(3)^2 + (1)^2} } = \frac{10}{\sqrt{(10)}} = \sqrt{(10)}[/tex]
⇒ d = √10 units
Hence, distance from point A(0,5) to y = -3 x - 5 is √10 units units.
To find the distance from point A(0,5) to the line y=-3x-5, we can use the distance formula.
Explanation:To find the distance from point A(0,5) to the line y=-3x-5, we can use the distance formula.
The distance formula is given by:
d = √((x2 - x1)² + (y2 - y1)²)
In this case, point A is (0,5) and the line is y = -3x - 5.
So, we can substitute the values into the formula:
d = √((x - 0)² + (y - 5)²)
d = √(x² + (y - 5)²)
To find the distance, we need to substitute the x and y values of a point on the line into the formula and solve for d.
Let's take the point (1, -8) as an example:
d = √((1)² + (-8 - 5)²)
d = √(1 + 169)
d = √170
So, the distance from point A(0,5) to the line y=-3x-5 is √170.

define the solution to a system of linear inequalities.
The solution to a system of linear inequalities is the set of values that satisfy all the inequalities at once, graphically represented as the overlapping shaded region on a coordinate plane.
Explanation:The solution to a system of linear inequalities is defined as the set of values that satisfy all inequalities in the system simultaneously. To find this solution set, each inequality is graphed on the same coordinate plane to determine the region where all inequalities overlap. Within this region, any point represents a solution to the system. If an inequality is non-strict (less than or equal to or greater than or equal to), the boundary line is included in the solution set and is usually drawn as a solid line. If the inequality is strict (less than or greater than), the boundary line is not included in the solution set and is depicted as a dashed line. The solutions are typically represented graphically by shading the area of the plane that satisfies all conditions.

The shorter leg of a right triangle is 6 feet shorter than the longer leg. The hypotenuse is 6 feet longer than the longer leg. Find the side lengths of the triangle.
The length of longer leg is 24 feet, shorter leg is 18 feet and hypotenuse is 30 feet.
Step-by-step explanation:
Let,
Longer leg = a = x
Shorter leg = b = x - 6
Hypotenuse = c = x + 6
As the triangle is right angles, therefore, using pythagoras theorem;
[tex]a^2+b^2=c^2\\(x)^2+(x-6)^2=(x+6)^2\\x^2+(x^2-12x+36)=x^2+12x+36\\x^2+x^2-12x+36=x^2+12x+36\\ 2x^2-12x+36=x^2+12x+36[/tex]
Adding (-x² - 12x-36) on both sides
[tex]2x^2-12x+36-x^2-12x-36=x^2+12x+36-x^2-12x-36\\x^2-24x=0[/tex]
Taking x common;
[tex]x(x-24)=0\\[/tex]
Either,
x=0
or,
x-24 = 0 => x=24
As length cannot be 0 therefore,
Longer leg = x = 24 feet
Shorter leg = x-6 = 24-6 = 18 feet
Hypotenuse = x+6 = 24+6 = 30 feet.
The length of longer leg is 24 feet, shorter leg is 18 feet and hypotenuse is 30 feet.

Mrs. Martini is 6 years more than 3 times as old as Tony. Eight years ago, she
was 2 years less than 9 times as old as he was then. Find each of their ages.
Mrs Martini age is 42 years and Tony age is 12 years
Step-by-step explanation:
The given is:
Mrs. Martini is 6 years more than 3 times as old as TonyEight years ago, she was 2 years less than 9 times as old as he was thenAssume that Tony is x years old now
∵ Mrs. Martini is 6 years more than 3 times as old as Tony
∵ Tony is x years old
- Multiply the age of Tony by 3 and add 6 to the product
∴ The age of Mrs Martini = 3 x + 6
8 years ago
- Subtract 8 from the age of each one
Tony age = (x - 8)
Mrs Martini age = (3 x + 6) - 8 = 3 x + 6 - 8 = 3 x - 2
∵ Eight years ago, Mrs Martini was 2 years less than 9 times as old
as Tony was then
- Multiply Tony age by 9 and subtract 2 from the product
∵ Tony age from 8 years ago = x - 8
∵ Mrs Martini age from 8 years ago = 3 x - 2
∴ 9(x - 8) - 2 = 3 x - 2
- Simplify the left hand side
∴ 9 x - 72 - 2 = 3 x - 2
- Add like terms
∴ 9 x - 74 = 3 x - 2
- Subtract 3 x from both sides
∴ 6 x - 74 = -2
- Add 74 to both sides
∴ 6 x = 72
- Divide both sides by 6
∴ x = 12
∵ x represents the age of Tony
∴ Tony is 12 years old
∴ 3 x + 6 is the age of Mrs Martini
- Substitute x by 12
∵ 3(12) + 6 = 36 + 6 = 42
∴ Mrs Martini is 42 years old
Mrs Martini age is 42 years and Tony age is 12 years

Answer: 2,000,000,000
Step-by-step explanation:
A series of books has 30 volumes, each with 700 pages. What is the total number of pages in the series?
Answer:
Step-by-step explanation:
Here we have to multiply to find the total...
30 volumes, then each individual book with 700 pages, therefore, the answer would be 21,000 pages
To calculate the total number of pages in the series, multiply the number of volumes (30) by the pages per volume (700) to get a total of 21,000 pages.
Explanation:The question asks for the total number of pages in a series of books, assuming each of the 30 volumes has 700 pages. Therefore, the calculation we need to perform is: 30 volumes × 700 pages per volume.
The formula to calculate the total number of pages is:
Total Pages = Number of Volumes × Pages per Volume
By inserting the given values into the formula:
Total Pages = 30 × 700 = 21,000 pages.
Hence, the total number of pages in the series is 21,000.

[tex]19 - \frac{6}{5}j[/tex]
written out on a computer keyboard, you would type: 19 - (6/5)j
Step-by-step explanation:
The terms that dont have a 'j' attached to them all group up and combine to this: 18 + (-5) + 6 = 18-5+6 = 13+6 = 19
The rest of the terms have a 'j', and they combine to: [tex]-\frac{2}{5}j - \frac{4}{5}j = \left(-\frac{2}{5} - \frac{4}{5}\right)j = \frac{-2-4}{5}j = -\frac{6}{5}j[/tex]
After combining both sets of like terms, we have 19 as the first result and [tex]-\frac{6}{5}j[/tex] as the second result. They are then added to get [tex]19 + \left(-\frac{6}{5}j\right) = 19 - \frac{6}{5}j[/tex]
We cant simplify any further because there are no like terms left.

Question 1:
No, \(x^3 \cdot x^3 \cdot x^3\) equals \(x^9\), while \(x^3 \cdot 3 \cdot 3\) equals \(9x^3\), representing different operations and values.
Question 2:
Incomplete. The expression \(1/x^3\) can be rewritten as \(x^{-3}\) using negative exponents.
Question 3:
Incorrect. The product of \(\sqrt{x}\) and \(4\sqrt{x}\) equals \(4x\), not \(5x\). Use exponents to simplify.
Question 4:
The expression \(x^{5/6} \cdot x^{1/6}\) simplifies to \(x\). Show the steps of exponent addition.
Question 5:
Unjustified. Determine equivalent expressions by simplifying each and comparing results. Justify based on mathematical properties.
Here's a review of your work:
Question 1:
Your reasoning is incorrect. The expressions are not equivalent because they represent different operations. \( x^3 \cdot x^3 \cdot x^3 \) means \( x \) multiplied by itself 3 times, which is \( x^9 \). \( x^3 \cdot 3 \cdot 3 \) is a multiplication of constants, which equals \( 9x^3 \). So, the expressions are not equivalent because they result in different values.
Question 2:
Your answer is incomplete. It seems like you've provided a template for simplifying radicals, but you haven't actually applied it to the given expression. To simplify \( \frac{1}{x^3} \), you can rewrite it as \( x^{-3} \).
Question 3:
Your answer is incorrect. The product of \( \sqrt{x} \) and \( 4\sqrt{x} \) is not simply \( 5x \). To rewrite it in simplest rational exponent form, you should use the property of exponents which states that \( \sqrt{a} = a^{1/2} \). So, \( \sqrt{x} \) is equivalent to \( x^{1/2} \), and \( 4\sqrt{x} \) is equivalent to \( 4x^{1/2} \). Multiplying these expressions together, you get \( 4x^{1/2} \cdot x^{1/2} = 4x^{1/2 + 1/2} = 4x^1 = 4x \).
Question 4:
You haven't shown your process for simplifying \( x^{\frac{5}{6}} \cdot x^{\frac{1}{6}} \). To simplify, use the property of exponents which states that when you multiply two terms with the same base, you add their exponents. So, \( x^{\frac{5}{6}} \cdot x^{\frac{1}{6}} = x^{\frac{5}{6} + \frac{1}{6}} = x^{\frac{6}{6}} = x^1 = x \).
Question 5:
You haven't justified which expressions are equivalent. To determine equivalence, you need to simplify each expression and compare them to each other.

What value represents the vertical translation from the graph of the
(x+5)2+3?
0 -5
O-3
Answer:
The value 3 represents the vertical translation upwards of [tex]f(x)[/tex] to [tex]g(x)[/tex]
Step-by-step explanation:
The question is incomplete or missing data.
The correct question
What value represents the vertical translation from the graph of the parent function [tex]f(x) = x^2[/tex] to the graph of the function
[tex]g(x) = (x + 5)^2 + 3[/tex]?
Given functions:
Parent function
[tex]f(x) = x^2[/tex]
Translated function
[tex]g(x) = (x + 5)^2 + 3[/tex]
Translation rules
For horizontal shift
[tex]f(x)\rightarrow f(x+c)[/tex]
If [tex]c>0[/tex] the function shifts [tex]c[/tex] units to the left.
If [tex]c<0[/tex] the function shifts [tex]c[/tex] units to the right.
For vertical shift
[tex]f(x)\rightarrow f(x)+c[/tex]
If [tex]c>0[/tex] the function shifts [tex]c[/tex] units to the up.
If [tex]c<0[/tex] the function shifts [tex]c[/tex] units to the down.
From the functions given the translation rule can be given as:
[tex]f(x)\rightarrow f(x+5)+3[/tex]
[tex]g(x)=f(x+5)+3[/tex]
This shows the graph is shifted left by 5 units and upwards by 3 units.
Thus the value 3 represents the vertical translation of [tex]f(x)[/tex] to [tex]g(x)[/tex]

Part 16) we know that
The solution of the inequality is the shaded area below the solid line
The slope of the solid line is negative
The y-intercept of the solid line is the point (0,2)
The x-intercept of the solid line is the point (2,0)
The slope of the solid line is

The linear equation of the solid line in slope intercept form is
[tex]y=-x+2[/tex]
therefore
The inequality that represent the graph is
[tex]y\leq -x+2[/tex]
Part 17) we know that
The solution of the inequality is the shaded area above the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is the point (0,-1)
The x-intercept of the dashed line is the point (3,0)
The slope of the dashed line is
[tex]m=(0+1)/(3-0)=\frac{1}{3}[/tex]
The linear equation of the dashed line in slope intercept form is
[tex]y=\frac{1}{3}x-1[/tex]
therefore
The inequality that represent the graph is
[tex]y>\frac{1}{3}x-1[/tex]

The never intersecting and the coplanar lines describe the parallel lines. The correct option is C and E.
What are parallel lines?
Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things.
Therefore, the never intersecting and the coplanar lines describe the parallel lines. The correct option is C and E.

What is
The equation of the line that passes through the points (5,-1) and (4,-5)
For this case we have that by definition, the equation of the line in the slope-intersection form is given by:
[tex]y = mx + b[/tex]
Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have two points through which the line passes:
[tex](x_ {1}, y_ {1}) :( 5, -1)\\(x_ {2}, y_ {2}) :( 4, -5)[/tex]
We found the slope:
[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-5 - (- 1)} {4-5} = \frac {-5+ 1} {- 1} = \frac {-4} {- 1} = 4[/tex]
Thus, the equation is of the form:
[tex]y = 4x + b[/tex]
We substitute one of the points and find b:

Dean is comparing prices on ground beef. Store A is selling 5 pounds of ground beef for $23.49. Store B is selling 8 pounds of ground beef for $36.96.
Which store is offering the better deal on ground beef?
Store B is offering the better deal on ground beef
Step-by-step explanation:
Dean is comparing prices on ground beef
Store A is selling 5 pounds of ground beef for $23.49Store B is selling 8 pounds of ground beef for $36.96We need to know which store is offering the better deal on ground beef
To find the better deal we must to find the unit price of each store
The unit price = total price ÷ number of pounds
∵ Store A is selling 5 pounds of ground beef for $23.49
∴ The unit price of Store A = 23.49 ÷ 5 = $4.698
∴ The unit price of Store A is $4.698 per pound
∵ Store B is selling 8 pounds of ground beef for $36.96
∴ The unit price of Store B = 36.96 ÷ 8 = $4.620
∴ The unit price of Store B is $4.620 per pound
∵ $4.620 < $4.698
∴ The unit price of Store B is less than the unit price of Store B
∴ Store B is cheaper than Store A, then it is offering the better deal
Store B is offering the better deal on ground beef

Which function represents the sequence: 4, 7, 10, 13, 16,...
Answer:
3n + 1
Step-by-step explanation:
Note the sequence has a common difference between consecutive terms, that is
7 - 4 = 10 - 7 = 13 - 10 = 16 - 13 = 3
This indicates that the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = 4 and d = 3, thus
[tex]a_{n}[/tex] = 4 + 3(n - 1) = 4 + 3n - 3 = 3n + 1
Answer:
[tex]\large\boxed{a(n)=3n+1}[/tex]
Step-by-step explanation:
It's an arithmetic sequence:
[tex]a(1)=4\\\\a(2)=a(1)+3=4+3=7\\\\a(3)=a(2)+3=7+3=10\\\\a(4)=a(3)+3=10+3=13\\\\a(5)=a(4)+3=13+3=16\\\vdots[/tex]
An explicit formula of an arithmetic sequence:
[tex]a(n)=a(1)+(n-1)d[/tex]
d - common difference
We have
[tex]a(1)=4,\ d=3[/tex]
Substitute:
[tex]a(n)=4+(n-1)(3)[/tex] use the distributive property
[tex]a(n)=4+3n-3[/tex]
[tex]a(n)=3n+1[/tex]
Name one point on the line y - 4 = 3(x + 2)
