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]

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.

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

Please help meeeeeeeeeee!!!!!!!!!!!!
DUE TONIGHT!!!!!!!!!
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.

Answer: 2,000,000,000
Step-by-step explanation:
Marcela estimates the distance between the library and town hall is 735 ft. The actual distance is 612 ft.
What is the percent error in Marcela's estimate?
Round your answer to the nearest tenth of a percent.
Enter your answer in the box.
Answer:
The error percentage in estimation is 20 %
Step-by-step explanation:
The estimated distance between library and town = 735 ft
The actual distance = 612 ft
The Error in estimation = Estimated Distance - Actual Distance
= 735 ft - 612 ft = 123 ft
So, the error in the estimation is 123 ft.
Now, [tex]\textrm{ Percentage in Error Estimation} = \frac{\textrm{The estimated Error}}{\textrm{The estimated value}} \times 100[/tex]
= [tex]\frac{123}{612} \times 100 = 20.098[/tex]
or, The error percentage in estimation is 20.09%
Now, rounding off the value to the nearest tenths of a %, we get:
The error percentage in estimation is 20 %

1. y = 4x + 3 for x = -1, 0,1
Answer:
-1, 3, 7
Step-by-step explanation:
y = 4(-1) + 3
y = -4 + 3
y = -1
y = 4(0) + 3
y = 0 + 3
y = 3
y = 4(1) + 3
y = 4 + 3
y = 7
To solve the linear equation y = 4x + 3, substitute the given x values (-1, 0, 1) into the equation to find the corresponding y values. The results are -1, 3, and 7 respectively.
Explanation:The question asks to solve the equation y = 4x + 3, for the values of x being -1, 0, and 1. This is a linear equation where y depends on x. To find the corresponding y values for each x value:
Substitute x = -1 into the equation. The calculation becomes: y = 4(-1) + 3 = -4 + 3 = -1.Substitute x = 0 into the equation. The calculation becomes: y = 4(0) + 3 = 0 + 3 = 3.Substitute x = 1 into the equation. The calculation becomes: y = 4(1) + 3 = 4 + 3 = 7.Hence, the values for y when x equals -1, 0, and 1 respectively are -1, 3, and 7.

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.What is the slope of the line that passes through the points (-6, -7) and

Final answer:
The slope of the line that passes through the points (-6, -7) and (-24, -7) is calculated using the slope formula and is found to be 0, indicating that the line is horizontal.
Explanation:
The question asks for the slope of the line that passes through the points (-6, -7) and (-24, -7). To calculate the slope, we use the formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. Plugging in our values, we get the slope = (-7 - (-7)) / (-24 - (-6)) = 0 / -18 = 0. Therefore, the slope of the line through these two points is 0, which means the line is horizontal.

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.

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.
