A Cell wall is a protective barrier that surrounds only plant cells, providing structural support.
A cell wall, a large central vacuole, and plastids like chloroplasts are all present in plant cells. The cell wall is a thick, stiff layer that surrounds and supports the cell structurally and physically. It is located outside the cell membrane.
What is cell wall?the dense, nonliving covering that protects and sustains the majority of plant, bacterial, fungal, and algal cells. cellular wall.
The cell membrane is a layer of defense that covers the surface of the cell and serves as a partition between the interior of a cell and its surroundings. The cell membrane also regulates the materials that enter and exit the cell.
A cell is protected by its cell membrane, also known as the plasma membrane. Additionally, it maintains a constant environment inside the cell, and that membrane serves a variety of purposes. One is to move compounds out of the cell that are harmful as well as nutrients into the cell.

The slope intercept form of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept. The given equation can be written in terms of slope in y = 0.6x + 5.
What is the equation for a straight line?A straight line can be written in the form of equation as, y = mx + c.
Two straight lines intersect each other only at one point.
When two straight lines are parallel to each other the angle between them is zero.
Given that,
The equation of the line is 12x - 20y = -100
In order to write the given equation in slope-intercept form, write the given equation in terms of y as,
12x - 20y = -100
=> 20y = 12x + 100
=> y = 12 / 20x + 100 / 20
=> y = 0.6x + 5
Where slope is 0.6 and y-intercepts is 5.
Hence, the slope-intercept form of the given equation is y = 0.6x + 5.

How to describe congruent triangles?
Congruency is a term used to describe two objects with the same shape and size.
In this case, two triangles are congruent if they have exactly the same three sides and exactly the same three angles. The equal sides and angles may not be in the same position.
For instance,
these triangles are congruent. They have the same sides but in different position.
Another example is
In this case the congruency is about angles. These 2 triangles have the same angles and the same sides but in different positions.
Another instance is
They are the same triangles but in different positions.
From the first question we can see that both triangles are congruent.
This imply that they are the same but in different position:
We can note that angle C is equal to angle T, therefore
[tex]\angle T=55[/tex]In the same way, angle U is equal to angle B, then we have
[tex]\angle B=59[/tex]We can find angle A by noticing that the interior angles of a triangle add up 180, that is
[tex]\begin{gathered} \angle A+\angle B+\angle C=180 \\ \angle A+59+55=180 \\ \angle A+114=180 \\ \angle A=180-114 \\ \angle A=66 \end{gathered}[/tex]Since angle V is equal to angle A, also V=66
Find the area and perimeter of the rectangle based on information given Length = 5 Width = x + 2
Given the length and the expression that represents the width of a rectangle, you need to remember that:
• The area of a rectangle can be calculated by multiplying its dimensions:

• The perimeter of a rectangle is:
[tex]P=2l+2w[/tex]Where "l" is the length and "w" is the width.
Then, knowing that:
[tex]\begin{gathered} l=5 \\ w=x+2 \end{gathered}[/tex]- You can set up that the area of this rectangle is:

Answer:
the graph given has a greater unit rate
Step-by-step explanation:
basically, you have to compare the gradients of both the graphs
one graph's equation is given i.e y=47/2 where 47/2 is the gradient/slope now find the gradient/slope of the given graph:
slope = x2-x1/y2-y1
chose any two coordinates on the graph and input them in the equation
I chose (2,94) and (4,188)
inputting them in the equation:
188-94/4-2
=94/2
now see which one is greater 47/2 or 94/2
94/2 is greater than 47/2 so it has a greater unit rate

The value of corresponding angle x is 157°.
What are properties of parallel lines?Properties of Parallel Lines:
The pairs of corresponding angles are equal.
The pairs of vertically opposite angles are equal.
The pairs of alternate interior angles are equal.
The pairs of alternate exterior angles are equal.
Given: m║n
So, using the property of parallel lines we have the angles on the same side of transversal are supplementary. Let 23° is tranversal to α, then
23° +α = 180°
⇒α = 180°-23°
⇒α = 157°.
Now, using the property of vertically opposite angles we have
α = x = 157°
⇒ x = 157°
Therefore, the value of x is 157°.

The same distance againstthe wind takes 3 hours.What's the maximum speed of Hal's airplanein still air? What's the speed of the wind?Click on the correct answer.3(x - y) = 6003(x + y) = 600x-speed of the airplane in still airy speed of the wind2(x - y) = 6002(x + y) = 60080888Ma
Take into account:
x = speed of the airplane
y = speed of the air
consider that the product in between time and speed is equal to the distance traveled in the time.
Then, if the airplane took 3 hours complete 600 miles, agaist the wind, you have that the distance traveled by the airplane is 3x without wind. The speed of the wind decelerates the airplane. The "distance traveled by the wind is 3y"
Then, when you subtract the previous terms you obtain:
3x - 3y = 600 factorize 3 left side
3(x - y) = 600
