13 is in the divisor3302 is in the dividend2 hundreds and 5 tens is written in the quotient2600 is subtracted from 3302 to give 702An unknown value represented by a box is being subtracted from 702We need to find this number
Lets write the steps above
∵ The dividend = 3302
∵ The divisor = 13
- 2 hundreds means 200 and 5 tens means 50
∵ The quotient = 200 + 50 + x
∵ Dividend = divisor × quotient
∴ (13 × 200) + (13 × 50) + (13 × x) = 3302
∵ 13 × 200 = 2600
- Subtract 2600 from the dividend
∴ 3302 - 2600 = 702
∵ 13 × 50 = 650
∴ 702 - 650 = 52 ⇒ 650 is the unknown value
∵ 13 × x = 13x
∵ 52 - 13x = 0
- Add 13 x to both sides
∴ 52 = 13x
- Divide both sides by 13
∴ x = 4
∴ 3302 ÷ 13 = 200 + 50 + 4
∴ 3302 ÷ 13 = 254
∴ From the steps above the missing number subtracted from

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

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.

3) Table A does not represent a function, but Table B represents a function.
4) Table A represents a function, but Table B does not represent a function.
Answer:
Table A represents a function, but Table B does not represent a function.
Step-by-step explanation:
We have to select the correct option among the given 4 options after judging the given two tables attached to this question.
The first table shows that for each x values there is only one y value. Therefore, this is a function.
But in the second table shows that for each x value there are multiple y values since we are getting y = 1 and 2 for x = 5.

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.

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.

Step-by-step explanation:
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
[tex]m=(0-2)/(2-0)=-1[/tex]
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

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:
[tex](x,y):(5,-1)\\-1=4(5)+b\\-1=20+b\\-1-20=b\\b=-21[/tex]
Finally, the equation is:
[tex]y = 4x-21[/tex]
Answer:

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.
For which discriminant is the graph possible
b2-4ac=0
b2-4ac=-1
b2-4ac=4
Answer:
"[tex]b^2-4ac=4[/tex]"
Step-by-step explanation:
By looking at the value of the discriminant in a quadratic, we can find the nature of roots.
Let the value of the discriminant be "D", so we can say:
D > 0 [2 distinct real roots]D = 0 [2 same real roots]D < 0 [no real roots]Graphically, we can write the points in order as:
D > 0, 2 cutting point in x-axisD = 0, 1 touching point in x-axisD < 0, NO cutting/touching point in x-axisLooking at the graph, we clearly see that there is 2 cutting points in the x-axis, so there are 2 roots. This means the value of the discriminant should be greater than 0 (positive value).
Out of the 3 choices given with discriminant formula, the last one has a value that is greater than 0:
4 > 0
Hence, last answer choice is right.
The discriminant determines whether a quadratic equation has real solutions and affects the appearance of the graph.
Explanation:The discriminant is calculated using the formula Δ = b² - 4ac. In order for the graph to be possible:
If Δ = 0, the quadratic equation will have one real root. The graph will touch the x-axis at one point.If Δ < 0, the quadratic equation will have no real roots. The graph will not intersect the x-axis and will be entirely above or below it.If Δ > 0, the quadratic equation will have two distinct real roots. The graph will intersect the x-axis at two points.Therefore, for the discriminant values given:
For Δ = 0, the graph is possible.For Δ = -1, the graph is not possible.For Δ = 4, the graph is possible.How do you Graph this

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]

Np i gotchu my dude
1. represents
2. Each y value
3. to exactly
4. x value
Hope this helps my dude ^^
Answer:
Explain wether the graph represents a function.The graph represents a function because each x-value corresponds to exactly one y-value.
For example, in the given graph you see that for x=2 there's only one corresponding value, which is, y=40, that's what defines a function. If you have a graph where a certain value of x has to y values, that means is not a function, because for one x-value would be more than one y-values, so that would be only a relation, not a function.
It's important to specify the right order, that is, if we say each y-value corresponds to exactly one x-value, that's not exactly de definition of a function, because it actually happens, because in a quadratic expression, 2 and -2 would be the same result 4, so one y-vale has two x-value, but it's still a function.
So, the right order is The graph represents a function because each x-value corresponds to exactly one y-value.

[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.
