The student's conclusion is incorrect because there is exactly one solution to the equation and this can be determined by using the arithmetic operations.
GIven :
A student concluded that 8x - 12 = 4( 1/2x - 6 ) has infinity many solutions.
The following steps can be used in order to determine the statement that describes the student's conclusion:
Step 1 - Write the given linear equation.
[tex]8x - 12 = 4 (\dfrac{1}{2}x-6)[/tex]
Step 2 - Simplify the above equation.
8x - 12 = 2x - 24
Step 3 - Subtract 2x on both sides in the above equation.
8x - 2x - 12 = 2x - 2x - 24
6x - 12 = -24
Step 4 - Add 12 on both sides in the above equation.
6x - 12 + 12 = 12 - 24
6x = -12
Step 5 - Divide by 6 on both sides in the above equation.
x = -2
Therefore, the correct option is B) The conclusion is incorrect because there is exactly one solution to the equation.

1.)
15 lb turkey
for $45.00
OR
11 lb turkey
for $34.10
Even though you didn't say what the question is, I'm going to assume that you need to calculate what is the best price for the amount of turkey.
In order to do this you must divide the price of each turkey by the number of pounds it weighs.
So,
45/15
and,
34.10/11
The first costs you $3 per pound of turkey, and the second costs $3.10 per pound of turkey, this means that the first is 10¢ cheaper per pound.

Find the prime factorization of 105 using division by primes. Show work please
Answer:
Factors of 105 are the list of integers that can be evenly divided into 105. There are overall 8 factors of 105 among which 105 is the biggest factor and 1, 3, 5, 7, 15, 21, 35, and 105 are positive factors. The sum of all factors of 105 is 192 and its factors in Pairs are (1, 105), (3, 35), (5, 21), and (7, 15).
Factors of 105: 1, 3, 5, 7, 15, 21, 35 and 105
Negative Factors of 105: -1, -3, -5, -7, -15, -21, -35 and -105
Prime Factors of 105: 3, 5, 7
Prime Factorization of 105: 3 × 5 × 7 = 3 × 5 × 7
Sum of Factors of 105: 192
Step-by-step explanation:
To calculate the factors of 105, we can use the division method. Let's start with 1.
105 ÷ 1 leaves remainder 0.
Since 105 is not an even number, 2 does not divide 105 completely. Thus, it leaves a remainder.
105 ÷ 3 leaves remainder 0.
105 ÷ 5 leaves remainder 0.
105 ÷ 7 leaves remainder 0.
105 ÷ 15 leaves remainder 0.
105 ÷ 21 leaves remainder 0.
105÷ 35 leaves remainder 0.
105 ÷ 105 leaves remainder 0.
Thus, the factors of 105 that we have obtained are 1, 3, 5, 7, 15, 21, 35, and 105.

Plse Help! I'll mark brianleist! A store sells 3000 Halloween-themed wigs at $30 each every month. For each $1 increase in price, they would sell 75 less wigs. What is the price that would minimize the store's revenue? What is the maximum revenue?
PLease show all your work, thank you
Answer:
$15
Step-by-step explanation:
The price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35). The maximum revenue is $170,625.
To find the price that would minimize the store's revenue, we need to determine the price at which the wig sales would be maximized.
Let's assume the price increase in dollars is represented by "x" (where x > 0).
The number of wigs sold can be calculated using the given information: for each $1 increase in price, 75 fewer wigs are sold.
So, the number of wigs sold at the price of $30 + x would be 3000 - 75x.
The revenue is calculated by multiplying the price per wig by the number of wigs sold. Therefore, the revenue function (R) can be expressed as:
R = (30 + x)(3000 - 75x)
To find the price that would minimize the store's revenue, we need to find the value of x that minimizes the revenue function. We can do this by finding the critical points of the revenue function.
To find the critical points, we differentiate the revenue function with respect to x and set it equal to zero:
dR/dx = 0
Differentiating R = (30 + x)(3000 - 75x) with respect to x:
dR/dx = (3000 - 75x) + (30 + x)(-75) = 0
Expanding and simplifying:
3000 - 75x - 2250 - 75x = 0
Combine like terms:
-150x - 5250 = 0
Solving for x:
-150x = 5250
x = 5250 / (-150)
x = -35
Since x represents the price increase, a negative value of x would correspond to a price decrease. So, the price that would minimize the store's revenue is $30 - $35 = -$5 (a price decrease of $5).
However, a negative price is not practical in this context. So, we should consider the price increase instead.
Therefore, the price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35).
To find the maximum revenue, we can substitute this price ($65) back into the revenue function:
R = (30 + 35)(3000 - 75 * 35)
Simplifying:
R = 65 * 2625
R = $170,625
Therefore, the maximum revenue is $170,625.

Graph the linear equation
Y=3/4 x + 2
Y-intercept: _________
Slope: _________
Answer:
Y-intercept: 2
Slope: 3/4 or 0.75
Step-by-step explanation:
You can use this formula to find the values
Y=Mx+B
M=Slope
B=Y-intercept
in this case, 3/4 is in the M spot, and 2 is in the B spot
So the Y-intercept is 2 and the Slope is 3/4 as a fraction or 0.75 as a decimal.
To graph, start at the point (0,B). Remember, in this problem, B is 2.
Start at (0,2) and plot a point. Then move over 4 to the right (the bottom number in the slope) and up 3 (the top number in the slope) and plot another point. Keep doing this for 3 or 4 points and then connect the dots with a straight line. There's the graph of Y=3/4 x + 2.

most 0.75 pounds. Write and solve an absolute-value inequality to find the range of acceptable weights. Graph
the solutions.
Answer:
t greater than or equal to 9.25
And
t less than or equal to 10.75
Step-by-step explanation:
Inequality shows a relationship between two numbers or two expressions.
The inequality of the range of acceptable weights is 0.1 ≤ x ≤ 9.25
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
Example:
2 > 1
3x > 6, x values will be greater than 3.
We have,
The targeted weight of the bag = 10 pounds
The weight of each bag differs from 10 pounds at most by 0.75 pounds.
The acceptable weight of the bag can be:
0.1 pound to 9.25 pounds.
i.e,
10 - 9.25 = 0.75
Let x = acceptable weights
The inequality of the range of acceptable weights is 0.1 ≤ x ≤ 9.25
Thus,
The inequality of the range of acceptable weights is 0.1 ≤ x ≤ 9.25

Which of the following can you conclude about a particle labeled 1 0n ?Check all that apply.
Answer:
B and C
Step-by-step explanation:
Firstly it is not A because an alpha particle has a mass and atomic number of 2. So it would be written 2, 2, alpha.
Next, we can see by its mass number of 1 that it has one nucleon (Confirming C) as electrons have negligible mass. Because it has then has an atomic number of 0, we can conclude that it is a neutron, as a proton would have given it an atomic number of 1. This proves B to be correct and D to be incorrect.
E is incorrect as beta particles have negligible mass.
F could be correct but there is no way to tell whether or not it has an electron so we cannot tick it.
Finally G is incorrect because we already worked out the one nucleon has to be a neutron.
