Answer: Your answer should be 1.
The given equation 2(x + 2) = 2 + 2x has zero solution. which is the correct answer would be an option (A).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The equation is given in the question following:
2(x + 2) = 2 + 2x
We have to determine the number of solutions to the given equation.
As per the given question, we have
⇒ 2(x + 2) = 2 + 2x
Apply the distributive property of multiplication, and
⇒ 2x + 4 = 2 + 2x
Rearrange the terms of variable x in the above equation,
⇒ 2x - 2x = 2 - 4
⇒ 0 = -2
This is not true, so the given equation has no solution.
Thus, the equation 2(x + 2) = 2 + 2x has zero solution.

2(a+7) - 7 = 9 what is the answer
Answer:
The answer is 1
Step-by-step explanation:
2(a+7)−7=9
Step 1: Simplify both sides of the equation.
2(a+7)−7=9
(2)(a)+(2)(7)+−7=9(Distribute)
2a+14+−7=9
(2a)+(14+−7)=9(Combine Like Terms)
2a+7=9
2a+7=9
Step 2: Subtract 7 from both sides.
2a+7−7=9−7
2a=2
Step 3: Divide both sides by 2.

What is the remainder when P(x) is divided by (x - 1)?
Answer:
The remainder is 0
Step-by-step explanation:
Polynomial Remainder Theorem
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).
We are given the values of P for various values of x as follows:
P(-2)=1
P(-1)=3
P(1)=0
P(2)=4
Applying the polynomial remainder theorem, finding the remainder when P(x) is divided by x-1 is just finding P(1).
Since P(1) = 0, the remainder is 0

the ratio of the length to the width of a rectangle is 10:6. if the perimeter of the rectangle is 160 meters, find the measure of the width.
Given:
The ratio of the length to the width of a rectangle is 10:6.
Perimeter = 160 meters
To find:
The measure of the width.
Solution:
Let the length and width of the rectangle be 10x and 6x respectively.
Perimeter of a rectangle is
[tex]P=2(l+w)[/tex]
where, l is length and w is width.
Putting P=160, l=10x and w=6x, we get
[tex]160=2(10x+6x)[/tex]
[tex]160=2(16x)[/tex]
[tex]160=32x[/tex]
Divide both sides by 32.
[tex]\dfrac{160}{32}=x[/tex]
[tex]5=x[/tex]
Now,
[tex]Width=6x[/tex]
[tex]Width=6(5)[/tex]
[tex]Width=30[/tex]
Therefore, the width of the rectangle is 30 meters.

Answer:
(b) and (c)
Step-by-step explanation:
When the equation of a line is given in slope-intercept form ([tex]y=mx+b[/tex]), m represents the slope of the line and b represents the y-intercept. As we can see, the two lines given have the same slope (-3), but different y-intercepts (the first line has a y-intercept of 4 and the second line has a y-intercept of -11).
Since the slopes of the two lines are the same, they will be parallel, and since their y-intercepts are different, they will not be the same line. Therefore, the two lines will not intersect (a solution to the system is any point where the two lines do intersect), and there is no solution to the system.
As a general rule:
If two lines have different slopes, there will be exactly one solution to the system (the lines will not be parallel and will intersect at exactly one place)If two lines have the same slope, and the same y-intercept, there will be infinitely many solutions (the two lines will be the same, and any point on the line will be a solution)If two lines have the same slope, but different y-intercepts, they will be parallel and will never intersect, so there will be no solution.What is 2 2/3 x 5/8

a. Find the slope of the line.
Answer:
Slope = -4
x intercept = 3
Step-by-step explanation:
See attachment for graph
Required
a. Determine the slope
b. Find the x intercept and explain what it represents
a. The slope
To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.
[tex](x_1,y_1) = (3,0)[/tex]
[tex](x_2,y_2) = (0,12)[/tex]
Next, we calculate the slope (m)
[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]
[tex]m = \frac{0 - 12}{3 - 0}[/tex]
[tex]m = \frac{- 12}{3}[/tex]
[tex]m = -4[/tex]
b. The x intercept
This is the point where [tex]y = 0.[/tex]
From the graph.
[tex]x = 3[/tex] when [tex]y = 0[/tex]
This implies that:
After 3 hours, the distance left to cover is 0miles.
In other words, she arrived home in 3 hours

How many meters are there in 2.5 kilometers? 2.5 km = m 2,500 250 25 20.5
Answer:
2500
Step-by-step explanation:
i calculated it
2.5 Km can be expressed as 2500 in meters.
To convert from kilometers to meters,
The conversion factor for kilometers to meters is
1 kilometer = 1000 meters.
Given that we want to convert 2.5 kilometers to meters, we can use the conversion factor:
2.5 km x 1000 meters/kilometer
= 2500 meters
So, there are 2500 meters in 2.5 kilometers.

Avinash bought an electric iron for rupees 900 and sold it for a gain of 10% he sold another electric iron at 5% loss which was bought for rupees 12000 on the transaction he has

Note: Cost of second iron must be 1200 instead of 12000.
Given:
Cost of first electric iron = 900
Grain on first electric iron = 10%
Cost of second electric iron = 1200
Loss on second electric iron = 5%
To find:
The correct statement for the given problem.
Solution:
We have,
Cost of first electric iron = 900
Grain on first electric iron = 10%
Profit on first iron is
[tex]900\times \dfrac{10}{100}=90[/tex]
Cost of second electric iron = 1200
Loss on second electric iron = 5%
Loss of second iron is
[tex]1200\times \dfrac{5}{100}=60[/tex]
Now, profit is 90 and loss is 60. Profit is more than loss.
Exact profit = Profit - Loss
Exact profit = 90 - 60
Exact profit = 30
Therefore, Avinash get a profit of Rs. 30 on the transactions. Hence, the correct option is c.

8. What, besides temperature, can make ocean water significantly denser?
pollutants
oxygen
salinity
pressure
Answer:
The answer is salinity because when the higher it is, the more it increases the density.
Beside temperature, salinity can make ocean water significantly denser.
What is temperature?"Temperature is a physical quantity that expresses hot and cold or a measure of the average kinetic energy of the atoms or molecules in the system."
What is salinity?"Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity)."
What is ocean water?"Seawater is a complex mixture of 96.5 percent water, 2.5 percent salts, and smaller amounts of other substances, including dissolved inorganic and organic materials, particulates, and a few atmospheric gases."
Salinity and density of water are directly proportional.Higher the salinity, higher the density.Salinity affects the movement of the ocean water current.
Hence, salinity make the ocean water significantly denser.

Compare the function with the parent function. Without graphing, what are the vertex, axis of symmetry, and transformations of the given function?
y = 8x - 21 - 7
Answer:
The parent function is: y = x
First, here we have two types of transformations, and we could define them in a general way as:
if we start with a function f(x)
Vertical dilation/contraction: A vertical dilation/contraction of scale factor A (A is always positive) is written as:
g(x) = A*f(x)
Vertical translation:
We can write a vertical translation of A units upwards as:
g(x) = f(x) + A
And a vertical translations of A units down can be written as:
g(x) = f(x) - A.
In this case, the transformations are:
first, a dilation of scale factor 8.
Then a translation down of 21 units
then another translation down of 7 units.
y = 8*X - 21 - 7
y = 8*x - 28.
As this is a linear equation, there are no axis of symmetry, we only could have a line of symmetry along the same line y = 8*x - 28
Again, as this function is a linear equation there is no vertex.
