What values of the variable cannot possibly be solutions for the given equation, without actually solving the equation?
[tex] \frac{6}{3x + 2} - \frac{1}{x - 4} = 0[/tex]
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
Answers
Answer:
the solution to the equation is 8. Any value apart from 8 is not a solution
Step-by-step explanation:
Given the equation
6/3x+2 - 1/x-4 = 0
6/3x+2 = 1/x-4
Cross multiply
6(x-4) = 3x+2
6x - 24 = 3x+2
6x-3x = 2 + 24
3x = 24
x = 24/3
x = 8
Hence the solution to the equation is 8. Any value apart from 8 is not a solution

Answer:
[tex]x = - \frac{2}{3} \: \: \: y = \frac{14}{3} [/tex]
Step-by-step explanation:
Since we know -7x=y we use the substitution method and plug it in the top equation.
[tex]x + - 7x = 4[/tex]
[tex] - 6x = 4[/tex]
[tex]x = - \frac{4}{6} [/tex]
or x=-2/3
Then plug it back in the the bottom equation

Step-by-step explanation:
The number of days, d, that it will take to build a house is given by
d= 720 divided by n
where n is the number of workers used each day.
Ali's company will take 40 days to build the house.
Hayley's company will take 30 days to build the house.
Hayley's company will have to use more workers each day than Ali's company.
How many more?
Answers
Answer:
6 more workers
Step-by-step explanation:
The relationship between days (d) and number of workers (n) is given by the equation;
d = 720 / n
Ali's company will take 40 days to build the house.
n = 720 / d
n = 720 / 40 = 18 workers
Hayley's company will take 30 days to build the house.
n = 720 / d
n = 720 / 30 = 24 workers
Hayley's company will have to use more workers each day than Ali's company.
How many more?
24 - 18 = 6 more workers

Find all real square roots of -36
Answers
Answer:
The answer is ±6.
Step-by-step explanation:
The positive and negative square roots of 36 are 6. and −6. Both 6, and −6 are square roots of 36 since they both give 36 when squared:...
6^2=6×6=36
(−6)2=(−6)×(−6)=36
All positive real numbers have a positive and negative real square root which are additive inverses of one another.
The principal square root is the positive one and is the one meant when we use the √... symbol. So:...
√36=6
If we want to refer to the negative square root, then just put a minus sign in front:...
−√36=−6
The two square roots of -36 are 6i and -6i, where i is the imaginary unit.
What is Number system?A number system is defined as a system of writing to express numbers.
Since the square of any real number is always non-negative, there is no real number whose square is equal to a negative number.
Therefore, the expression √(-36) has no real square roots.
However, we can express the square root of -36 using imaginary numbers.
By definition, the imaginary unit "i" is equal to the square root of -1. Using this definition, we can rewrite √(-36) as:
√(-36) = √(36) × √(-1) = 6i
Therefore, the two square roots of -36 are 6i and -6i, where i is the imaginary unit.

Y = x+3
Step-by-step explanation:
You want to start by figuring out how to get Y alone.
So to get it alone so you add +3 on both sides
Y - 3 = x
+3. +3
Positive 3 and Negative 3 cancel out making it zero.
Visual: 3 - 3 = 0
Since you cant take or add anything from x you leave it as + 3 so the answer should be.

Here is a diagram of a person standing next to a tree.
The diagram shows two centimeter rulers.
The tree and the person are drawn to the same scale.
The person is approximately 1.75 m tall.
Using the scale diagram, estimate the height of the tree in meters.
15 points + Brainiest + Heart
Answers
1.75* 2= 3.5
The tree is 3.5m
The estimated height of the tree is approximately 5 meters.
To estimate the height of the tree using the scale diagram, we need to compare the height of the person on the diagram to the height of the tree.
Given that the person's height is approximately 1.75 meters, we can use the scale of the diagram to make the estimation.
Let's assume that the scale on the diagram is such that each centimeter on the ruler corresponds to 1.75 meters in real life.
By measuring the height of the person on the diagram using the ruler, let's say it corresponds to 2 centimeters.
Now, using the scale of 1.75 meters per centimeter, we can calculate the estimated height of the tree:
2 centimeters * 1.75 meters/centimeter = 5 meters
Therefore, based on the scale diagram, the estimated height of the tree is approximately 5 meters.

Give your answer to 2 dp.
please answer for heart, comment, 5 star rating, and brainliest
Answers
Answer:
£683.10 in New York.
Step-by-step explanation:
Given the following data;
iPhone costs in London = £799
iPhone costs in Paris = €850
iPhone costs in New York = $970
£1 = €1.17 and £1 = $1.42
First of all, to find the cheapest (lowest) price for the three phones we would have to convert the prices to Pounds (£).
a. iPhone costs in London = £799
b. iPhone costs in Paris = €850
To find the price in Pounds (£);
£1 = €1.17
iPhone costs in Paris = €850/€1.17
iPhone costs in Paris = £726.50
c. iPhone costs in New York = $970
To find the price in Pounds (£);
£1 = $1.42
iPhone costs in New York = $970/$1.42
iPhone costs in New York = £683.10
Therefore, the lowest price for the iPhone is £683.10
