Store B is offering the better deal on ground beef

Step-by-step explanation:

Dean is comparing prices on ground beef

We 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

Answer:

$100\%=165$100%=165​.

Step-by-step explanation:

Answer:

4%

Step-by-step explanation:

165 is what % of 4125.

Let x represent the % in decimal form

4125*x = 165

Isolate x by dividing both sides by 4125

x = 0.04

0.04 = 4%

You find this by moving the decimal two places to the right

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:

[tex]y = 4x-21[/tex]

c = 56

Step-by-step explanation:

The two angles 'c' and '124' form a straight angle. They add to 180

c+124 = 180

c+124-124 = 180-124 ... subtract 124 from both sides

c+0 = 56

c = 56

Answer:

Step-by-step explanation:

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.

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.

Hence, table B is not a function. it is just a relation. (Answer)

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.

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.

The never intersecting and the coplanar lines describe the parallel lines. The correct option is C and E.

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.

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:

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.

Answer:

[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.

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.

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:

Graphically, we can write the points in order as:

Looking 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.

The discriminant is calculated using the formula Δ = b² - 4ac. In order for the graph to be possible:

Therefore, for the discriminant values given:
