Step-by-step explanation:
The given expression simplifies to B. 13p - 17q + 2 by combining like terms.
The given expression that requires simplification is 7p + 20 - 13q - 4q - 18 + 6p. To simplify an algebraic expression, combine like terms, which are terms that contain the same variable raised to the same power. In this case, we combine the terms with p and the terms with q, as well as the constant terms separately.
First, combine the terms with p: 7p + 6p equals 13p.
Second, combine the terms with q: -13q - 4q combines to -17q.
Lastly, combine the constant terms: 20 - 18 equals 2.
Putting it all together, the simplified expression is 13p - 17q + 2, which corresponds to option B.
The domain of f(x) is the set of all real values except 7, and the domain of g(x) is the set of all real values except –3. What describes the domain of (gºf)(x)?
What is the value of x to the nearest tenth?
x=2.1
x=3.4
x=9.6
x=13.1
The value of x is 9.6.
To find the value of x to the nearest tenth, we can use the angle bisector theorem, which states that in a triangle, an angle bisector divides the opposite side into two segments that are proportional to the other two sides of the triangle.
Given that:
[tex]\[\frac{6.3}{5.4} = \frac{11.2}{x}\][/tex]
We can solve for x by cross-multiplying:
[tex]\[6.3 \cdot x = 5.4 \cdot 11.2\][/tex]
[tex]\[6.3x = 60.48\][/tex]
Now, divide both sides by 6.3 to isolate x:
[tex]\[x = \frac{60.48}{6.3}\][/tex]
[tex]\[x \approx 9.6\][/tex]
So, the value of x to the nearest tenth is 9.6. Therefore, the correct option is x = 9.6.
A thief steals an ATM card and must randomly guess the correct three-digit pin code from a 10-key keypad. Repetition of digits is allowed. What is the probability of a correct guess on the first try?
The probability of a correct guess on the first try will be [tex]0.001[/tex] .
What is Probability ?Probability is the ratio of number of favorable outcome to the
i.e. Probability [tex]P(E)=\frac{number\ of\ favorable\ outcome}{Total\ number\ of\ outcomes.}[/tex]
We have,
An ATM Card having three-digit code.
Repetition of digits is allowed.
So,
As Repetition is allowed, and we have [tex]10-[/tex]key keypad, and have to guess [tex]3[/tex] digit code,
Then
Total number of outcomes [tex]=10*10*10=1000[/tex]
And
Number of favorable outcome [tex]=1[/tex]
So,
Probability [tex]P(E)=\frac{number\ of\ favorable\ outcome}{Total\ number\ of\ outcomes.}[/tex]
[tex]P(E)=\frac{1}{1000}[/tex]
[tex]P(E)=0.001[/tex]
So, the Probability of correct guess is [tex]0.001[/tex] .
Hence, we can say that the probability of a correct guess on the first try is [tex]0.001[/tex] .

A student's saving account has a balance of $4900 on September 1. Each month the balance declines by $350. What is the slope
Answer:
The slope is [tex]-\frac{350}{month}\[/tex]
Step-by-step explanation:
This saving account is declining a fixed amount every month, this means that the function that represents this decline is linear.
The other thing we know is that originally (september 1), the account has a balance of $4900, and this is the intercept.
Therefore, for a linear function depending of the variable "x", we can write that
[tex]f(x)= (-\frac{350}{month}x+4900)\[/tex]
where the units were factored. Then the slope is
[tex]-\frac{350}{month}\[/tex]

Four consecutive integers sum to 70. What is the least of the 4 integers?
The staff at Larry's Lawns spends their workday mowing lawns, raking, and bagging leaves. They work an average of nine hours per day. The mowing and raking typically takes six hours and an average of thirty-six bags of leaves are filled. Assuming the bags are filled at a constant rate, what is the average time it takes to fill one bag of leaves?
The average time it takes to fill one bag of leaves is approximately 0.17 hours.
Explanation:To find the average time to fill one bag of leaves, we use the formula
Average Time=Total Time÷Total Bags. In this scenario, the total time spent is the average workday hours, which is 9 hours, and the total number of bags filled is 36.
So,
Average Time=9hours÷36bags=0.25 hours/bag.
Therefore, the average time it takes to fill one bag of leaves is 0.25 hours or 15 minutes. This means, on average, it takes 15 minutes to fill each bag of leaves.
In summary, the staff at Larry's Lawns spends 9 hours a day on lawn-related tasks, with mowing and raking taking 6 hours. Since they fill an average of 36 bags of leaves in that time, each bag takes approximately 0.25 hours or 15 minutes to fill, assuming a constant rate of filling.
To find the average time it takes to fill one bag of leaves at Larry's Lawns, divide the total time spent filling bags by the number of bags filled. Time per bag = 1/6 hours per bag.
Explanation:To find the average time it takes to fill one bag of leaves, we need to divide the total amount of time spent filling bags by the number of bags filled. In this case, the staff at Larry's Lawns spend 6 hours mowing and raking and fill 36 bags of leaves. So to find the average time per bag, we divide 6 hours by 36 bags:
Time per bag = Total time / Number of bags = 6 hours / 36 bags
Since we want the average time per bag, we can simplify the fraction:
Time per bag = 1/6 hours per bag.

What is the 7th term of the geometric sequence 4, −20, 100, …? −312,500 −12,500 62,500 1,562,500?
Answer: The correct option is (C) 62500.
Step-by-step explanation: We are given to find the 7-th term of the following geometric sequence :
4, −20, 100, . . .
We know that
the n-th term of a geometric sequence with first term a and common ratio r is given by
[tex]a_n=ar^{n-1}.[/tex]
For the given geometric sequence, we have
first term, a = 4
and common ratio r is given by
[tex]r=\dfrac{-20}{4}=\dfrac{100}{-20}=~~.~~.~~.~~=-5.[/tex]
Therefore, the 7-th term of the given geometric sequence is
[tex]a_7=ar^{7-1}=4\times(-5)^6=4\times 15625=62500.[/tex]
Thus, the required 7-th term is 62500.
Option (C) is CORRECT.
Write an expression for the following situation and solve. Mr. Simms bought 20 pencils. He used 1/4 of the pencils and then gave 4 to his students. How many total pencils does Mr.Simms use and give away? Show your work.
Mr. Simms used 1/4 of the 20 pencils he bought, which equals 5 pencils, and gave away an additional 4 pencils, totaling to 9 pencils used and given away.
To solve how many total pencils Mr. Simms uses and gives away, we first find out how many pencils he used by taking 1/4 of the 20 pencils he bought. To do this, we multiply 20 by 1/4:
20 times 1/4 = 5
Mr. Simms used 5 pencils. He also gave away 4 pencils to his students. To find the total number of pencils used and given away, we add the pencils used to the pencils given away:
5 (used) + 4 (given away) = 9
Therefore, Mr. Simms used and gave away a total of 9 pencils.

Which graph represents a phase shift of pi/2 units right for the graph of y=cos x
Solution:
we are given that [tex]y=cos x[/tex]
Here we are going to plot two curves one for cosx and the othere also of cosx but after making a phase shift of [tex]\pi/2[/tex]
When we do a phase shift by an angle of theta , in that case actaully we add angle negative theta .
For example when we shift the phase of sinx by [tex]\pi/2[/tex] we get [tex]sin(x-\pi/2).[/tex]
Hence we are going to plot the curve of
[tex]y=cosx\\ \\ y=cos(x-\pi/2)=sinx\\[/tex]
Hence the correct option is B.

Select the correct product.
(2x + 9)(x + 1)
2x2 + 11x + 9
3x2 + 11x + 9
2x2 - 7x + 9
2x2 + 11x + 10
Final answer:
To find the product of (2x + 9) and (x + 1), we use the distributive property and combine like terms, resulting in 2x² + 11x + 9.
Explanation:
The student is asking for the correct product when multiplying the binomials (2x + 9) and (x + 1). This is a math problem involving algebraic multiplication.
To find the product, we apply the distributive property (also known as FOIL method in binomials):
Multiply 2x by x to get 2x².Multiply 2x by 1 to get 2x.Multiply 9 by x to get 9x.Multiply 9 by 1 to get 9.Combine the terms to get the final product: 2x² + 2x + 9x + 9, which simplifies to 2x² + 11x + 9.
The correct product of (2x + 9)(x + 1) is 2x² + 11x + 9.
