Lysosomes are important to the health of cells of the following reason:
They break down worn-out cell parts that are no longer needed.What are Lysosomes?Lysosomes can be defined as protective organelles that contain enzymes that can be used to break down negative microorganisms that invade the body. The Lysosomes are very important to the health of cells because they protect the cells from being damaged by viruses and bacteria that can limit the growth of the body.
So, the option that explains why lysosomes are important to the health of cells is that they break down worn-out cell parts that are no longer needed. Option A is accurate.

In the metric system, 1 gran is the mass of 1 milliliter of water. So, a 2-liter bottle of water has a mass of 2 kilograms. A gallon of water weighs about 8 pounds. What is the mass of a gallon of water to the nearest tenth of a kilogram?Parts A-D
We know that:
[tex]1\text{ lb }\to0.45\text{ kg}[/tex]A)
Using the conversion law, we can calculate the conversion factor as a fraction:
[tex]\frac{0.45\text{ kg}}{1\text{ lb}}=\frac{9\text{ kg}}{20\text{ lb}}[/tex]B)
Now, we multiplicate 8 pounds by the conversion factor:
[tex]\frac{9\text{ kg}}{20\text{ lb}}\cdot8\text{ lb }\approx3.6\text{ kg}[/tex]C)
The pound units cancel, resulting in an answer given in kilograms.

What is 4 notes that are important to the concept of. Absolute Value and the Additive
This problem is about absolute value.
Four important notes to remember are:
• Absolute value is the modulus of a number, that is, includes only the number without any signs.
• The absolute value of a number can be positive, when the number is positive, that is
[tex]|x|=x[/tex]• The absolute value can be negative if the number is negative
[tex]|x|=-x[/tex]• The absolute value of zero is zero.
[tex]|0|=0[/tex]There you have it, those are 4 important notes to keep in mind about absolute value.

To start solving the system, Elena wrote:4x + y = 14x + 8y = 36And then she wrote:4x + y =14x + 8y = 36 --7y=-351. What were Elena's first two moves? What might be possible reasons for those moves?
Looking at the equations after Elena started solving the system, we can see that the second equation is different.
Each coefficient is 4 times greater the old coefficiets. That means equation B was multiplied by 4. She did this step to make both equations have the term 4x.
Then, in the next step, she subtracted the equations. Since both equations have 4x, subtracting the equations would cancel this term, then she can solve the result for y.
Therefore, in this step, she Subtracted the equations, this way she can cancel out the variable x.

Terrance says that (5, 4) is a point on the line of y-4=1/2(x-5). He says it’s impossible to find another point on the line because the equation is in point-slope form. Explain Terrance’s error.
Terrance’s error is that he limits the solution of the equation to one ordered pair
How to determine the error in Terrance’s claim?The equation is given as
y - 4 = 1/2(x - 5)
The solution is given as
(5, 4)
The above solution is true
This is so because; when x = 5, the value of y is 4
i.e.
y - 4 = 1/2(5 - 5)
y - 4 = 0
y = 4
Next, we set x to another value (say x = 9)
So, we have
y - 4 = 1/2(5 - 9)
y - 4 = -2
y = 6
This means that the equation can have another solution
In this case, it is (9, 6)
Hence, one ordered pair cannot be the solution to the equation

Find the domain of the logarithmic function and then graph the function. y= In (4x - 5) Find the domain of the function.
Domain = ( 5/4 , ∞)
Explanations:The logarithm function is given as:
y = ln (4x - 5)
the domain of the functions is a set of all the values of x that makes the function true (defined)
Note that the natural logarithm of a negative number is undefined. This means that the natural logarithm (ln) is only defined for positive numbers
This means that in y = ln (4x - 5), 4x -5 has to be greater than zero for the function to be defined.
Set 4x - 5 > 0
4x > 5
x > 5 / 4

Answer:
The rate of change of elevation tends to a constant value.
Explanation:
The average rate of change of e(x) on the interval [a, b] defined as
[tex]m_{\text{avg}}=\frac{e(b)-e(a)}{b-a}[/tex]which explicitly we can write as
[tex]m_{\text{avg}}=\frac{\sqrt[]{b-10}-\sqrt[]{a-10}}{b-a}[/tex]Now, the question is, what happens to m_avg as we increase b while keeping a fixed?
As b becomes large then √b -10 becomes √b and b - a becomes b (since a is comparatively small); therefore, m_avg becomes
[tex]m_{\text{avg}}=\frac{\sqrt[]{b-10}-\sqrt[]{a-10}}{b-a}\Rightarrow\frac{\sqrt[]{b}-\sqrt[]{a-10}}{b}\Rightarrow\frac{\sqrt[]{b}}{b}[/tex][tex]\Rightarrow m_{\text{avg}}=\frac{\sqrt[]{b}}{b}[/tex]which for any fixed value of b is a constant.
The same behaviour can be extrapolated by looking at the graph of e(x).
As can be seen from the graph, as x increases, the slope of the function becomes flatter and flatter, meaning it tends to be a constant. In other words, for large values of x, you can approximate the slope of the function by a straight line.

Explanation
to find the total cost we need add the cost of the blocks to the cost of the total boards, so
Step 1
find the total cost of the blocks
a) when having the cost per unit and the amount, we just need to do a multiplication, so
[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the blocks= 7.97}\frac{\text{ \$}}{block}*25\text{ Blocks} \\ tota\text{l cost of the blocks= \$ 199.25} \end{gathered}[/tex]Step 2
now, the total cost of the boards:
[tex]\begin{gathered} total\text{ cost= rate*amount} \\ replace \\ tota\text{l cost of the boards= 14}\frac{\text{ \$}}{board}*4\text{8 boards} \\ tota\text{l cost of the boards= \$ 672} \end{gathered}[/tex]Step 3
finally, add the costs to find the total
[tex]\begin{gathered} total\text{ cost= \$199.25+672} \\ total\text{ cost= 871.25} \end{gathered}[/tex]therefore, Ken will pay $ 871.25 for these items

The given set is,
13, 19, 7
19 - 13 < 7 < 19 + 30
6 < 7 < 49
This set follows the condition of a triangle.
Therefore, this set can be used to form a triangle.
(b)
The given set is,
25, 12 , 13
25 - 12 < 13 < 25 + 12
13 < 13 < 37

-2×+5y=-13×+2y=11[tex] - 2 \times + 5y = - 1[/tex]
nealmiyasmith20, this is the solution:
-2× + 5y= -1
3× + 2y= 11
___________
Step 1: Isolating x on the first equation:
-2× + 5y= -1
-2x = - 1 - 5y
Dividing by -2 at both sides:
-2x/-2 = -1/-2 - 5y/-2
x = 1/2 + 5y/2
______________________
Step 2: Substituting x and solving for y on the second equation:
3× + 2y = 11
3 ( 1/2 + 5y/2) + 2y = 11
3/2 + 15y/2 + 2y = 11
19y/2 = 11 -3/2
19y/2 = 19/2
Multiplying by 2/19 at boths sides:
19y/2 *2/19 = 19/2 * 2/19
y = 1
___________________
Step 3: Substituting y and solving for x on the first equation:
-2× + 5y = -1
-2x + 5 * 1 = -1
-2x + 5 = -1
-2x = -1 - 5
-2x = -6
Dividing by -2 at both sides:
-2x/-2 = -6/-2
x = 3
Step 4: Proving that x = 3 and y = 1 are correct on the second equation:
3× + 2y = 11
3 * 3 + 2 * 1 = 11
9 + 2 = 11
11 = 11
We proved that x = 3 and y = 1 are correct

Order of operations was it evaluated correctly? 5^(2) + 1^(2) = 6(2) = 36EXPLAIN your reasoning. Thank you
The answer to the operation is as follows:
5^(2) + 1^(2) = 5*5 + 1*1 = 25 + 1 = 26.
Here, we have to remember PEMDAS. First, we solve parentheses, then exponents (or exponentiation operations); then, multiplications, divisions, and, after all this, addition and subtractions.
In the above operation, we solve first the raising of 5 to 2, then 1 raised to 2. We sum the result of both operations. So the value of 36 is not correct. The correct value is 26.
