The graph approaches 3 as x approaches infinity.
The graph approaches 4 as x approaches infinity.
Answer: The graph approaches -3 as x approaches infinity will be the correct option which describes the behavior of the function.
Explanation:
Given Function: f(x)= [tex]\frac{3x}{4-x}[/tex]
Now, we divide numerator and denominator by x and we get,
⇒ [tex]f(x)= \frac{3}{4/x-1}[/tex]
If x approaches to infinity.
Therefore, [tex]\lim_{x\rightarrow \infty}f(x)[/tex]
then [tex] f(x)\rightarrow -3[/tex]

Step-by-step explanation:
If bill rides his bike 3 miles to Fred's house and then walks with Fred the remaining 1 mile to school, it will take him 30 minutes. But if he rides the entire distance, it will take him only 20 minutes. what is his walking and biking speed?
Final answer:
Bill's biking speed is 12 mph and his walking speed is 4 mph. We find the biking speed from the 20-minute ride distance and solve for the walking speed using the time difference in the 30-minute trip.
Explanation:
The student is asking about calculating walking and biking speeds based on different times to cover distances. To solve this, we'll use the information that Bill takes 30 minutes to ride 3 miles and then walk 1 mile, but only 20 minutes to ride the entire 4 miles to school.
First, we want to find the speed for each part of the trip when Bill takes 30 minutes. Since we know the total time and distances, we can set up two equations using the relationship speed = distance / time. Let's define biking speed as 'b' and walking speed as 'w'.
For the 30-minute trip:
3 miles / b + 1 mile / w = 0.5 hours
For the 20-minute, all biking trip:
4 miles / b = (1/3) hours
From the second equation, we find that b = 4 miles / (1/3 hour) = 12 mph. Substitute 'b' in the first equation:
3 miles / 12 mph + 1 mile / w = 0.5 hours
1/4 hour + 1 mile / w = 0.5 hours
To solve for 'w', we'll subtract the bike time from the total time:
1 mile / w = 0.5 hours - 1/4 hour
1 mile / w = 1/4 hour
So, the walking speed 'w' is 1 mile / (1/4 hour) = 4 mph.
Therefore, Bill's biking speed is 12 mph, and his walking speed is 4 mph.

Which system of equations can be used to find the roots of the equation 4x^5-12x^4+6x=5x^3-2x?
A). Y=-4x^5+12x^4-6x and y=5x^3-2x
B). Y=4x^5-12x^4+5x^3+4x and y=0
C). Y=4x^5-12x^4+6x and y= -5x^3+2x
D). Y=4x^5-12x^4+6x and y=5x^3-2x
Answer:
D). Y'= [tex]4x^{5}-12x^{4}+6x[/tex] and y'= [tex]5x^{3}-2x[/tex]
Step-by-step explanation:
We are given the equation [tex]4x^{5}-12x^{4}+6x=5x^{3}-2x[/tex].
On simplifying this equation, we get [tex]4x^{5}-12x^{4}-5x^{3}+8x=0[/tex]
i.e. Let, Y'= [tex]4x^{5}-12x^{4}+6x[/tex] and y'= [tex]5x^{3}-2x[/tex]
Now, according to the options,
A) Y = [tex]-4x^{5}+12x^{4}-6x[/tex] = -Y' , that means the graph will be inverse of the required graph.
B) As the coefficient of 'x' in our given equation and the equation of option B are different, both will have different graphs.
C) As y = [tex]-5x^{3}+2x[/tex] = -y', this means that the graph will be inverse of the required graph.
Hence, all above options are discarded and so option D is correct.
Suppose that it takes Jenny 2 hours to wax a car if she works alone and it takes Carol 4 hours to wax the same car if she works alone. How long will it take them to wax the car, in hours, if they work together?
Calvin and Alvin together take approximately 1.875 hours, or 1 hour and 52.5 minutes, to wax a car.
To find out how long it takes Calvin and Alvin to wax a car together, we can use the formula for working together:
[tex]\[\frac{1}{T} = \frac{1}{T_1} + \frac{1}{T_2}\][/tex]
Where:
-[tex]\( T \)[/tex] is the time taken when working together,
- [tex]\( T_1 \)[/tex] is the time taken by Calvin alone, and
- [tex]\( T_2 \)[/tex] is the time taken by Alvin alone.
Given:
- Calvin takes 3 hours to wax a car alone, so [tex]\( T_1 = 3 \)[/tex] hours,
- Alvin takes 5 hours to wax a car alone, so [tex]\( T_2 = 5 \)[/tex] hours.
Substitute the values into the formula:
[tex]\[\frac{1}{T} = \frac{1}{3} + \frac{1}{5}\][/tex]
To solve for T, first find a common denominator:
[tex]\[\frac{1}{T} = \frac{5}{15} + \frac{3}{15} = \frac{8}{15}\][/tex]
Now, invert both sides of the equation to isolate T:
[tex]\[T = \frac{15}{8} \text{ hours} \approx 1.875 \text{ hours}\][/tex]
So, it takes Calvin and Alvin approximately 1.875 hours, or 1 hour and 52.5 minutes, to wax a car together.
The Correct Question is :
Suppose that it takes Calvin 3 hours to wax a car if he works alone and it takes Alvin 5 hours to wax a car if he works alone.
How long does it take them to wax a car if they work together? Write an equation and solve for the unknown.

Darryl deposits $1,500 into a savings account that has a simple interest rate of 2.7%. Lori deposits $1,400 into a savings account that has a simple interest rate of 3.8%. If no other transactions are made, who will have more money in their account after 10 years? How much more?
Answer:
Lori will make $27.00 more.
Step-by-step explanation:
The formula to calculate simple interest is
A = P(1+rt)
P = Principal amount
r = rate of interest ( in decimal )
t = time
First we calculate Darryl's deposit, so put the values in the formula
A = 1,500(1 + 0.027×10)
A = 1,500 ( 1+0.27 )
A = 1,500 × 1.27
A = $1905
Now we will calculate Lori's deposit
A = 1,400 ( 1 + 0.038 × 10 )
A = 1,400 ( 1 + 0.38 )
A = 1,400 × 1.38
A = $1,932
Lori will make money after 10 years = $1,932
Darryl will make money after 10 years = $1905
so Lori will make more than Darryl, the difference will be = 1,932 - 1,905 = $27
After 10 years Lori will have make $27.00 more in their account.

Kendra has $ 7.75 $7.75 in nickels and quarters. if she has 13 13 more quarters than nickels, how many of each coin does she have?
Setting up a system of equations, we find that there is an error in the problem or the information provided.
Explanation:Let's set up a system of equations to solve this problem.
Let's say the number of nickels is x and the number of quarters is y. From the information given in the problem, we can set up two equations:
x + y = 7.75 (since the total value of the coins is $7.75)y = x + 13 (since there are 13 more quarters than nickels)Now we can solve this system of equations. Substituting the second equation into the first equation, we get:
x + (x + 13) = 7.75
Simplifying the equation, we get:
2x + 13 = 7.75
Subtracting 13 from both sides, we have:
2x = -5.25
Dividing both sides by 2, we find:
x = -2.625
Since we can't have a negative number of coins, there must be an error in the problem or the information provided.

The explicit rule for a sequence is given.
an=−2n+7
What is the recursive rule for the sequence?
a1=7; an=an−1+2
a1=5; an=an−1−2
a1=−2; an=an−1+7
a1=7; an=an−1−2
The recursive rule is: [tex]\(a_1 = 7\); \(a_n = a_{n-1} - 2\)[/tex]. The correct option is D.
Sure, here's the step-by-step solution:
1. Start with the explicit rule for the sequence: [tex]\(a_n = -2n + 7\)[/tex].
2. To find the recursive rule, we need to express [tex]\(a_n\)[/tex] in terms of [tex]\(a_{n-1}\)[/tex], the previous term in the sequence.
3. Replace [tex]\(n\)[/tex] in the explicit rule with [tex]\(n-1\)[/tex] to represent the previous term:
[tex]\[a_{n-1} = -2(n-1) + 7\][/tex]
[tex]\[a_{n-1} = -2n + 2 + 7\][/tex]
[tex]\[a_{n-1} = -2n + 9\][/tex]
4. Since [tex]\(a_n = a_{n-1} - 2\)[/tex], substitute the expression for [tex]\(a_{n-1}\)[/tex] from step 3 into the recursive rule:
[tex]\[a_n = (-2n + 9) - 2\][/tex]
[tex]\[a_n = -2n + 9 - 2\][/tex]
[tex]\[a_n = -2n + 7\][/tex]
So, the recursive rule is [tex]\(a_1 = 7\); \(a_n = a_{n-1} - 2\)[/tex]. Therefore, the correct answer is D.

Answer:
Angela needed to multiply [tex]\frac{1}{2}[/tex] by each of the terms inside the parentheses.
Her product when multiplying [tex]\frac{1}{2} X 2[/tex] is incorrect.
Step-by-step explanation:
For simplifying the expression [tex]\frac{1}{2}(3x+2)[/tex], we need to multiply [tex]\frac{1}{2}[/tex] by each of the terms inside the parentheses.
So,
Upon multiplying [tex]\frac{1}{2}[/tex] by 6X we get 3X.
Upon multiplying [tex]\frac{1}{2}[/tex] by 2 we get 1.
Thus the final simplified expression must be 3x+1
So we can say,
Angela needed to multiply [tex]\frac{1}{2}[/tex] by each of the terms inside the parentheses.
Her product when multiplying [tex]\frac{1}{2} X 2[/tex] is incorrect.
Angela attempted to use the distributive property to simplify the expression 1/2 (6X + 2), but while she correctly simplified 1/2 * 6X to 3X, she incorrectly simplified 1/2 * 2 as 2, instead of 1. Therefore, her method was correct, but the computation was incorrect.
Explanation:In mathematics, the Distributive Property is used to simplify expressions like the one Angela has used - 1/2 (6X + 2). In order to distribute correctly, Angela should perform the operation of multiplication for each term inside the parentheses by the 1/2 outside the parentheses. Therefore, it should look like this: (1/2 * 6X) + (1/2 * 2). This will simplify to 3X + 1. The issue with Angela's work was that, while she correctly simplified 1/2 * 6X to 3X, she incorrectly simplified 1/2 * 2 as 2, instead of the correct 1 value. Therefore, the correct statement about Angela's work is "Her product when multiplying is incorrect".

An amusement park charges an admission fee of 50 dollars for each person. let c be the cost (in dollars) of admission for p people. write an equation relating c to p . then use this equation to find the cost of admission for 17 people.
The equation relating the cost of admission (c) to the number of people (p) is c = 50 * p. For 17 people, the total cost is c = 50 * 17, which equals $850.
To write an equation relating c to p, we set c, the cost of admission for p people, equal to the admission fee per person multiplied by the number of people. Given that the admission fee per person is $50, the equation is:
c = 50 * p
Using this equation to find the cost of admission for 17 people:
c = 50 * 17
c = $850
Therefore, the cost of admission for 17 people is $850.
