Answer:
(A)
[tex]x=-4[/tex]
(B)
[tex]g(x)=\frac{3x-1}{x+4}+4[/tex]
(C)
[tex]x=-17[/tex]
Step-by-step explanation:
we are given
[tex]f(x)=\frac{3x-1}{x+4}[/tex]
(a)
we know that
any function is undefined when denominator =0
so, we can set denominator =0
and then we can solve for x
[tex]x+4=0[/tex]
[tex]x=-4[/tex]
So, it does not have solution at [tex]x=-4[/tex]
(b)
If g(x) is a vertical shift up 4 units from f(x)
Whenever we shift vertically upward by 'a' units , we always add 'a' to y-value
so, we get
g(x)=f(x)+4
we get
[tex]g(x)=\frac{3x-1}{x+4}+4[/tex]
Graph:
(C)
we can set g(x)=8
and then we can solve for x
[tex]8=\frac{3x-1}{x+4}+4[/tex]
[tex]8\left(x+4\right)=3x-1+4\left(x+4\right)[/tex]
[tex]8x+32=7x+15[/tex]
[tex]x=-17[/tex]
Which of the following could be the equation of the function below?
Answer:
[tex]y=-2cos (2(x+\pi ))-1[/tex]
Step-by-step explanation:
From the graph, we can see that y = -3 when x = 0.
So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.
1. y = -2 cos (4(x + pi)) - 1 = -2 cos (4(0 + pi)) - 1 = 3
2. y = 2 cos(x + pi) = 2 cos(0 + pi) = -1
3. y = -2 cos (2(x + pi)) - 1 = -2 cos (2(x + pi)) - 1 = -3
Therefore, the equation of this graph is y = -2 cos (2(x + pi)) - 1.
As an estimation we are told £3 is €4.
Convert £12.30 to euros.
Give your answer rounded to 2 DP.
Answer:
€16.40
Step-by-step explanation:
First, we need to divide £12.30 by 3 to find out how many groups of 3 there is:
12.3 ÷ 3 = 4.1
Now we can multiply this by 4 to find the euro equivalent:
4.1 * 4 = 16.4
So £12.30 is €16.40
Brian wants to purchase a piece of fabric that is between 49 and 53 inches long. He can choose between three pieces of fabric. Choice A is 4 3/4 feet long. Choice B is 4 1/2 feet long. Choice C is 4 1/4 feet long. Which price of fabric should Brian purchase?
Answer:
the correct answer is c
Step-by-step explanation:
Answer:
Choice C.Step-by-step explanation:
We now that Brian wants the piece of fabric between 49 and 53 inches, this range is expressed like this
[tex]49<x<53[/tex]
Now, to choose the right answer, we have to transform the from feet to inches and see which one falls into this interval.
Choice A.We know that 1 ft equals 12 in. If we have [tex]4\frac{3}{4}=\frac{19}{4} ft[/tex], how much inches would be?
[tex]\frac{19}{4}ft\frac{12in}{1ft}=57in[/tex]
As you can see, the choice A is not the right answer because is more than 53.
Choice B.We do the same process. We know that, [tex]4\frac{1}{2}=\frac{9}{2}ft[/tex] how much inches would be?
[tex]\frac{9}{2}ft\frac{12in}{1ft}=54in[/tex]
Choice B is not the answer neither, because it's outside the interval.
Choice C.[tex]4\frac{1}{4}=\frac{17}{4}ft[/tex] how much inches would be?
[tex]\frac{17}{4}ft\frac{12in}{1ft}=51in[/tex]
As you can observe, choice C is in the interval. Therefore, the right answer is choice C, because 51 inches is between 49 and 53 inches.
Woody wants to earn $250 to buy a bicycle by selling lemonade it cost him$0.05 dollars to make a glass of lemonade,which he sells for$0.25. how many drinks does he have to sell to earn$250
Answer:
1,250 drinks
Step-by-step explanation:
Woody spends $0.05 to make a glass of lemonade and makes $0.25 when he sells one, so his net gain is $0.20. 250 / .20 is 1,250.
Final answer:
Woody needs to sell 1,250 glasses of lemonade to earn the $250 required to buy a bicycle. Calculated by dividing the goal ($250) by the profit per glass ($0.20), which is the difference between the selling price ($0.25) and the cost price ($0.05).
Explanation:
Woody is operating a small business of selling lemonade and seeks to achieve a certain amount of total revenues to purchase a bicycle. To solve this, one must determine the profit per glass of lemonade sold, which is the selling price minus the cost to make it. Since Woody sells a glass for $0.25 and it costs $0.05 to make, the profit per glass is $0.25 - $0.05 = $0.20.
To calculate the total number of glasses Woody needs to sell to earn $250, divide his goal by the profit per glass. Thus:
Total number of glasses = ($250 / $0.20 per glass) = 1250 glasses
Hence, Woody must sell 1,250 glasses of lemonade to earn enough money to buy the bicycle.

Lines b and c are parallel.
What is the measure of 2?
m2 = 31°
m2 = 50°
m2 = 120°
m2 = 130°
The correct measure of angle 2 is [tex]\( m\angle2 = 130\°\)[/tex].
To find the measure of angle 2, we need to use the properties of parallel lines and the angles formed when a transversal intersects them. When a transversal intersects two parallel lines, corresponding angles are equal, and alternate interior angles are also equal.
In the given scenario, lines b and c are parallel, and we assume that the transversal intersects these parallel lines at points not shown in the conversation. Let's denote the angles formed by the intersection of the transversal with line b as angles 1, 2, 3, and 4, and with line c as angles 5, 6, 7, and 8, respectively.
Since lines b and c are parallel, we have the following relationships:
1. [tex]\( m\angle1 = m\angle5 \)[/tex] (corresponding angles)
2. [tex]\( m\angle2 = m\angle6 \)[/tex] (corresponding angles)
3. [tex]\( m\angle3 = m\angle7 \)[/tex] (corresponding angles)
4. [tex]\( m\angle4 = m\angle8 \)[/tex] (corresponding angles)
5. [tex]\( m\angle1 = m\angle8 \)[/tex] (alternate interior angles)
6. [tex]\( m\angle2 = m\angle7 \)[/tex] (alternate interior angles)
7. [tex]\( m\angle3 = m\angle6 \)[/tex] (alternate interior angles)
8. [tex]\( m\angle4 = m\angle5 \)[/tex] (alternate interior angles)
From the given options, we can eliminate [tex]\( m\angle2 = 31\° \)[/tex] and [tex]\( m\angle2 = 50\° \)[/tex] because these options would imply that [tex]\( m\angle6 \) and \( m\angle7 \)[/tex] are also [tex]\( 31\° \) and \( 50\° \)[/tex], respectively. This would mean that the sum of the angles in the triangle formed by the transversal and line c would be less than [tex]\( 180\° \)[/tex], which is impossible.
Next, we consider [tex]\( m\angle2 = 120\° \)[/tex]. If this were true, then [tex]\( m\angle7 \)[/tex] would also be [tex]\( 120\° \)[/tex]. However, this would imply that the sum of the angles in the triangle formed by the transversal and line c would be [tex]\( 120\° + 60\° \)[/tex] (since [tex]\( m\angle6 \) and \( m\angle8 \)[/tex] would be supplementary, adding up to [tex]\( 180\° \)[/tex]), which again is impossible because the sum of angles in any triangle is [tex]\( 180\° \).[/tex]
Finally, we consider [tex]\( m\angle2 = 130\° \)[/tex]. This option is possible because if [tex]\( m\angle2 = 130\° \)[/tex], then [tex]\( m\angle7 \)[/tex] would also be [tex]\( 130\° \)[/tex]. The remaining angle in the triangle formed by the transversal and line c (which is [tex]\( m\angle6 \) or \( m\angle8 \)[/tex]) would be [tex]\( 180\° - 130\° = 50\° \)[/tex]. This satisfies the triangle angle sum property, as [tex]\( 130\° + 50\° = 180\° \)[/tex].
Therefore, the correct measure of angle 2 is [tex]\( m\angle2 = 130\° \)[/tex].
The complete question is:
Lines b and c are parallel. What is the measure of 2?

The GCF of 18 and 27 is 9. This means that 9 is the largest number that can evenly divide both 18 and 27 without leaving any remainder.
Step 1: Find the Factors of Each Number
To find the factors of a number, you identify all the whole numbers that divide that number without leaving a remainder. Here are the factors of 18 and 27:
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 27: 1, 3, 9, 27
Step 2: Identify the Common Factors
Next, we look for the common factors between the two sets of factors. These are the numbers that appear in both lists:
Common factors of 18 and 27: 1, 3, 9
Step 3: Determine the Greatest Common Factor (GCF)
The GCF is the greatest or largest number among the common factors. In this case, the greatest common factor among 1, 3, and 9 is 9.
Therefore, the GCF of 18 and 27 is 9. This means that 9 is the largest number that can evenly divide both 18 and 27 without leaving any remainder.

How to calculate the AB distance?
To calculate the distance AB between points A (x1, y1) and B (x2, y2), first draw a right triangle with segment ¯AB in the hypothalamus. AC is a horizontal distance, so it's just a difference in x-coordinates: | (x2-x1) |. Similarly, BC is the vertical distance | (y2-y1) |. ..
The vertical distance of the line (Ax + By + c = 0) from point
is equal to | Ax'+ By' + c√A2 + B2 |. Where (x', y') are the coordinates of the point. Since we need the distance of the line from the origin, the coordinates will be (0,0), which is the vertical distance of the line from the origin.

Circle K has a center at (3,7) and has a radius of 1. Circle K' has a center of (7,–3) with a radius of 1. What is the transformation of circle K to circle K'?
Answer:
I think it's rotated 90 degrees clockwise
Step-by-step explanation:
The transformation of circle K to circle K' is a translation, specifically a movement of 4 units to the right and 10 units down, represented by T(4, -10).
Explanation:The transformation that maps circle K to circle K' is a translation. In a translation, every point of the object moves the same distance in the same direction. For circle K to circle K', this would be a shift 4 units to the right and 10 units down. The coordinates of the center of the circle move from (3,7) to (7,-3). We can calculate this movement by subtracting the initial coordinates from the final ones: (7-3, -3-7) = (4, -10). Therefore, the transformation would be written as T(4, -10).

Whats in the [ ] is the whole part
Answer:
4 is the [ ] in whole part.Step-by-step explanation:
Given equation [(x-1)/3]=(x+3)/4
Let us first get rid denominators from both sides.
On cross multiplying both sides, we get
4(x-1) = 3(x+3)
4x-4 = 3x+9
Adding 4 on both sides, we get
4x-4+4 = 3x+9+4
4x = 3x +13
Subtracting 3x on both sides, we get
4x-3x = 3x-3x +13
x = 13.
Now, we need to find the value of [ ] fraction We have [(x-1)/3] in given equation.
Plugging x= 13 in (x-1)/3, we get

The easiest way to get this is through divide and conquer.
Therefore take 1, 2, 3, 5, 7, 9, and 11.
1 is a factor obviously.
2 is a factor since 80 is divisible by 80. We found a factor so divide the value 80 by 2 and we get 40. Is 2 a factor of 40? Yep, so divide again and we have 20. Is 2 a factor of 20. Yep. So is 10. So now we are at 5. But 5 is not a factor of 2. 5 is a factor of 5.
So we have the following 1, 2, 2, 2, 2, and 5. Thus 2 and 5 are your prime factors of 80. Note this is NOT the prime factorization of the number 80. That value is 2^4 * 5. You asked the prime factors of 80. Those are 2 and 5.

Trisha needs to make at least 50 gift bags for an event. Each gift bag will contain at least 1 thumb drive or 1 key chain. She wants to use at least 5 times as many key chains as thumb drives. She has 25 thumb drives and 200 key chains.
Let x represent the number of key chains. Let y represent the number of thumb drives.
Write an inequality for this situation.
To ensure Trisha has at least 5 times as many key chains as thumb drives in each gift bag, the inequality x ≥ 5y can be used, where x is the number of key chains and y is the number of thumb drives. Considering she needs to make at least 50 bags, the inequality x + y ≥ 50 is also relevant.
For Trisha to satisfy the condition of having at least 5 times as many key chains as thumb drives in each gift bag, the following inequality can represent her situation:
x ≥ 5y
Here, x is the number of key chains and y is the number of thumb drives. Trisha must also create at least 50 gift bags, so another inequality to consider is the total number of gift bags:
x + y ≥ 50
Since Trisha has 25 thumb drives (y) and 200 key chains (x), she is limited by the number of thumb drives. The maximum number of gift bags she can create with one thumb drive in each is 25 bags, which means she can use up to 125 key chains (5 times 25). Thus, Trisha can satisfy the requirement by using all 25 thumb drives and up to 125 key chains, ensuring there's a minimum of one thumb drive or key chain per bag.

If f(x) =-x2 +6x -1 and g(x)=3x2-4x-1 find f-g (x)
Answer:
- 4x² + 10x
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= - x² + 6x - 1 - (3x² - 4x - 1) ← distribute
= - x² + 6x - 1 - 3x² + 4x + 1 ( collect like terms )
= - 4x² + 10x
Final answer:
To find f-g (x), subtract g(x) from f(x) and combine like terms. The resulting function is f-g (x) = -4x² + 10x.
Explanation:
To find the difference of the functions f(x) and g(x), denoted as f-g (x), we simply subtract the function g(x) from f(x). In the given problem:
f(x) = -x² + 6x - 1
g(x) = 3x² - 4x - 1
We subtract the expressions:
f-g (x) = (-x² + 6x - 1) - (3x² - 4x - 1)
Removing the parentheses and simplifying, we get:
f-g (x) = -x² + 6x - 1 - 3x² + 4x + 1
Combine like terms:
f-g (x) = -4x² + 10x
Thus, the function f-g (x) is -4x² + 10x.
