What are the two equations that need to be solved to find the solutions for the absolute value equation |2x-3|=x+6?
2x – 3 = x + 6 and 2x – 3 = –x – 6
2x – 3 = x + 6 and 2x + 3 = –x + 6
2x – 3 = x + 6 and 2x – 3 = x – 6
2x – 3 = x + 6 and 2x + 3 = x + 6
The equations to solve for [tex]\( |2x-3|=x+6 \)[/tex] are [tex]\( 2x - 3 = x + 6 \)[/tex] and [tex]\( 2x - 3 = -(x + 6) \).[/tex]
Let's solve the absolute value equation |2x-3|=x+6 step by step.
We'll start by writing down the equation:
|2x - 3| = x + 6
Since the absolute value expression |2x - 3| can be either positive or negative, we'll split the equation into two cases:
Case 1: 2x - 3 = x + 6
Case 2: 2x - 3 = -(x + 6)
Let's solve Case 1:
2x - 3 = x + 6
Subtract x from both sides:
2x - x - 3 = 6
Simplify:
x - 3 = 6
Add 3 to both sides:
x = 9
Now, let's solve Case 2:
2x - 3 = -(x + 6)
Distribute the negative sign:
2x - 3 = -x - 6
Add x to both sides:
2x + x - 3 = -6
Simplify:
3x - 3 = -6
Add 3 to both sides:
3x = -3
Divide both sides by 3:
x = -1
So, the solutions to the equation |2x-3|=x+6 are x = 9 and x = -1.

What is line?A line is collection of various points on a surface which together joins two points on a surface. Equation of a line looks like y=a +b x where b is the slope of line.
How to make graph?We have been given an equation y=-2x and we have to find the graph of equation and for that we need to find points and for this we have to put the values of x which gives the values of y.
At x=0 ,y=0
At x=1 ,y=-2*1=-2
At x=2 ,y=-2*2=-4
At x=-1 ,y=-2*-1=2
Coordinates will be (0,0),(1,-2),(2,-4),(-1,2)
If we find these points on this line then will surely be able to find these points.
Hence the statement which is true is that Yes, the points shown on the line would be part of y = −2x.

The population of a local species of beetle can be found using an infinite geometric series a1=960 and the common ratio is .25 write the sum in sigma notation and calculate the sum of possible that will be the upper limit of this population
Sigma 960 (1/4)^i-1 ; the sum is 1280
Signa 960 (1/4)^-1 the sun is divergent
Sigma 960 (1/4)^i sum is 1280
Sigma (1/4)^i sum is divergent
I=1 for them all
The answer is:
Sigma 960 (1/4)^i-1 ; the sum is 1280
Step-by-step explanation:We are given the first term of the geometric sequence as:
[tex]a_1=960[/tex]
Also, the common ratio of the terms in geometric sequence is: [tex]\dfrac{1}{4}[/tex]
We know that if the series is a geometric series than the sum of the terms is given by:
[tex]a+ar+ar^2+.....\\\\=a(1+r+r^2+....)\\\\=\sum ar^{n-1}[/tex]
where a is the first term of the series and r is the common difference.
Here a=960
and r=1/4
Hence,
The sum of the series is:
[tex]=\sum 960(\dfrac{1}{4})^{i-1}[/tex]
Now we know that the sum of the infinite geometric series is given by:
[tex]S=\dfrac{a}{1-r}[/tex]
where S is the sum of the series.
Hence, here the sum of the series is calculated by:
[tex]S=\dfrac{960}{1-\dfrac{1}{4}}\\\\\\S=\dfrac{960}{\dfrac{3}{4}}\\\\\\S=\dfrac{960\times 4}{3}\\\\\\S=1280[/tex]
Hence, the sum is: 1280
ILL GIVE BRAINLIEST !!!1 A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
Step 1: m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle)
Step 2: m∠w − m∠z = 90 degrees (corresponding angles)
Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z
Step 4: So, m∠x + m∠y = m∠w
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of corresponding angles)
Step 2; it should be m∠w + m∠z = 180 degrees (supplementary angles)
Step 1; it should be m∠x + m∠y + m∠z = 90 degrees (corresponding angles)
Step 2; it should be m∠w + m∠z = 90 degrees (alternate exterior angle)

Which of the relationship below are function
A functions B and D are valid functions because they meet the criteria of each x value having only one corresponding y value.
Function B: You mentioned that B is a function because each x value has only one corresponding y value. In mathematical terms, a function is defined as a relation between a set of inputs (x values) and a set of outputs (y values), where each input (x) maps to exactly one output (y). So, if B satisfies this definition, it is indeed a function.
Function D: Similar to B, if D also adheres to the definition of a function, where each x value corresponds to only one y value, then it is a function as well.
Function A: You mentioned that for A, the x value of 1 has 2 y values. In mathematical terms, a function cannot have one input (x) mapping to multiple outputs (y). If this is the case for A, it does not meet the definition of a function.
Function C: You mentioned that for C, the x value of 7 has 2 y values, 10 and 3. Again, if one input (x) is associated with multiple outputs (y) in C, it does not qualify as a function.
In summary, functions B and D are valid functions because they meet the criteria of each x value having only one corresponding y value. Functions A and C do not meet this criterion and are not functions in the mathematical sense.

A 7.5 kg block is placed on a table. If it's bottom surface area is 0.6m2, how much pressure does the block exert on the tabletop?
Final answer:
The pressure exerted by a 7.5 kg block on a tabletop is calculated as the force due to its weight divided by the surface area. This results in a pressure of 122.5 Pascals (Pa).
Explanation:
The pressure exerted by an object on a surface is calculated by dividing the force it applies, which is its weight (a result of gravity), by the area over which the force is distributed. In this case, to find the pressure exerted by a 7.5 kg block on a tabletop with a bottom surface area of 0.6m2, we use the formula for pressure (P), which is P = Force (F) / Area (A).
To calculate the force, we need to know that the weight of the block is the product of its mass (m) and the acceleration due to gravity (g), where g is approximately 9.8 m/s2. So, the weight (F) is:
F = m × g = 7.5 kg × 9.8 m/s2 = 73.5 N
To calculate pressure (P), we then divide the force by the area:
P = F / A = 73.5 N / 0.6 m2 = 122.5 Pa
Therefore, the pressure exerted by the block on the tabletop is 122.5 Pascals (Pa).
The value of m in the following system of equations is:
m-2n=8
n=m-2
A) m= -4
B) m= -6
C) m= 2
D) None of the choices are correct
The correct option is A. [tex]m=-4[/tex]. By substituting the second equation into the first one in the system of equations, the value of m is -4.
The value of m in the system of equations can be found by substitution or elimination. Starting with the given equations:
[tex]m - 2n = 8 (1)[/tex]
[tex]n = m - 2 (2)[/tex]
Using the second equation (2) to substitute for n in the first equation (1):
[tex]m - 2(m - 2) = 8[/tex]
[tex]m - 2m + 4 = 8[/tex]
[tex]-m + 4 = 8[/tex]
[tex]-m = 8 - 4[/tex]
[tex]-m = 4[/tex]
[tex]m = -4[/tex]
This means that the value of m is -4, which corresponds to option A.
You make both rocking chairs and bar stools. You charge $100 for every rocking chair and $40 for every bar stool. Which expression represents your income if you sell r rocking chairs and b bar stools?
Answer:
The answer is [tex]Income=100*r+40*b[/tex]
Step-by-step explanation:
In this case we have to construct an expression that describe the income of selling the rocking chairs ($100 each - r) and the bar stool ($40 each - b), so the total income will depend on the addition of this two variables multiplied by its individual price, this is:
[tex]Income=100*r+40*b[/tex]
The answer is [tex]Income=100*r+40*b[/tex]
P(A∩B)=1150,P(A|B)=1120,P(B)=?
For the given probabilities P(A∩B) = 1150 and P(A|B) = 1120, using Bayes' theorem for conditional probability, the probability of event B, P(B), is found to be approximately 1.027.
Explanation:The topic of this question is probability, specifically concurrent events in probability theory. Here, we use Bayes' theorem for conditional probability which states that P(A|B) = P(A ∩ B) / P(B).
Given that P(A∩B) = 1150 and P(A|B) = 1120, we can plug these values into the formula to find P(B). Hence, P(B) = P(A ∩ B) / P(A|B), substituting the given numbers, we get P(B) = 1150 / 1120 = 1.027 approximately.
So P(B), the probability of event B occurring, we would expect to be approximately 1.027 (or 102.7% assuming the probabilities were in decimal form to start with).

Alright, let's solve the problem with these given values.
The formula for calculating the probability of B in the context of A and B both happening is:
`P(A and B) / P(A|B)`.
In this case, the probability of A and B occurring is 1150, while the likelihood of A given that B has occurred is 1120. We can substitute these values into the formula:
So, P(B) = P(A and B) / P(A|B)
Substitute the given into the formula:
P(B) = 1150 / 1120 = 1.0267857142857142
Therefore, the Probability of event B (P(B)) is approximately 1.027 when rounded to three decimal places.
