Answer:
y ≤ [tex]\frac{1}{3}[/tex] x - 4
Step-by-step explanation:
the first step is to obtain the equation of the line.
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (3, - 3) ← 2 points on the line
m = [tex]\frac{-3-(-4)}{3-0}[/tex] = [tex]\frac{-3+4}{3}[/tex] = [tex]\frac{1}{3}[/tex]
the line crosses the y- axis at (0, - 4 ) ⇒ c = - 4
y = [tex]\frac{1}{3}[/tex] x - 4 ← equation of the line
----------------------------------------------
the shaded region below the line indicates the values that are less than y
the solid line indicates that y can equal the values on the line (≤ )
the solution is then
y ≤ [tex]\frac{1}{3}[/tex] x - 4
Adrian and Rory started comic book collections at the same time. Adrian started with 12 comic books and buys 4 more each month. Will they ever have the same number of comic books ? If so after how many months ? Use an equation to justify your answer
No, Both will not have the same amount of comic books because they add the same number each month.
What is an Equations?Equations are mathematical statements with two algebraic expressions on either side of an equals (=) sign. It illustrates the equality between the expressions written on the left and right sides. To determine the value of a variable representing an unknown quantity, equations can be solved. A statement is not an equation if there is no "equal to" symbol in it. It will be regarded as an expression.
Adrian started with 12 comic books and buys 4 more each month.
Rory started with 8 comic books and buys 4 more each month.
let x be the number of books.
A(x) = 4x+12
Rory starts with 8 comic books and add 4 comic books each month.
R(x) = 4x+8
Hence, Both will not have the same amount of comic books because they add the same number each month. There will be 4 additional comic books for Adrian.

Line q passes through points (6,8 )and( 3,4). Line r is perpendicular to q . What is the slope of line r
Answer:
The slope of line r is -3/4
Step-by-step explanation:
First, let's find the slope of line q. We can find the slope by finding the change in y over change in x.
[tex]\displaystyle{m=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
Therefore, substitute in:
[tex]\displaystyle{m=\dfrac{8-4}{6-3}}\\\\\displaystyle{m=\dfrac{4}{3}}[/tex]
Therefore, the slope of line q is 4/3. Since we want to find the slope of line r and we know by the given that line r is perpendicular to line q. By the definition of perpendicular line is [tex]\displaystyle{m_1m_2=-1}[/tex].
Let [tex]m_1[/tex] be slope of the line q which is 4/3. Therefore, substitute in and solve for [tex]m_2[/tex] (slope of line r)
[tex]\displaystyle{\dfrac{4}{3}m_2=-1}\\\\\displaystyle{4m_2=-3}\\\\\displaystyle{m_2=-\dfrac{3}{4}}[/tex]
Therefore, the slope of line r is -3/4

Kelsie works at a bicycle shop as a salesperson. She records the number of bicycles she sells daily. Here is the probability distribution of B = the number of bicycles Kelsie sells on a randomly selected day, and T the time she spends filling out daily sales reports. 2 B = # of bicycles sold T = time (minutes) Probability 40 20 10 0. 05 0. 15 0. 50 0. 30
a) Calculate E(B)
b) Calculate the mean time she spends filling out daily reports.
c) Calculate the standard deviation for both random variables
The amount of time Kelsie should spend doing daily sales reports is 9.5 minutes.
What is meant by discrete distribution?If a random variable has a limited number of outcomes or a countable number, it is discrete (i.e. the integers are infinite, but are able to be counted).
The discrete distribution presented reveals that the expected value of Kelsie's time spent completing daily sales reports is 9.5 minutes.
The discrete distribution given is:
P(X = 0) = 0.3
P(X = 10) = 0.5
P(X = 20) = 0.15
P(X = 30) = 0.05
The average of a discrete distribution is equal to the sum of each result times the probability associated with that outcome, so:
E(X) = 0(0.3) + 10(0.5) + 20(0.15) + 30(0.05) = 9.5
Therefore, the amount of time Kelsie should spend doing daily sales reports is 9.5 minutes.

What do you understand by discrete distribution?In statistics, a discrete distribution is a probability distribution that estimates the probability of a certain discrete, finite outcome. Simply put, as opposed to a continuous distribution, the discrete probability distribution aids in determining the probabilities of the occurrence of a specific event expressed in terms of positive, non-decimal, or whole integers.
The discrete distribution given is:
P(X = 0) = 0.3
P(X = 10) = 0.5
P(X = 20) = 0.15
P(X = 30) = 0.05
The average of a discrete distribution is equal to the sum of each result times the probability associated with that outcome, so:
E(B) = 0(0.3) + 10(0.5) + 20(0.15) + 30(0.05) = 9.5

2: mZ1=55* because Z1 and the 55* angle are vertical angles
3: mZ2=125* because Z2 and the 55* angle are supplementary
4: mZ2 cannot be determined from the information
5: mZ1=180*-55*
6: mZ2=180*-55*-45*
Three true statements about the angles of the given figure are,
1. angle 1 and the 55 degree angle are adjacent.
5. angle 1 = 180 degree - 55 degree
6. angle 2 = 180 degree - 55 degree - 45 degree.
How are complementary angles defined?Complementary angles are two angles whose measures add up to 90 degrees. For example, an angle of 45 degrees and an angle of 45 degrees are complementary. When two angles are complementary, they form a right angle. The symbol for complementary angles is ∠A + ∠B = 90°.
What is the difference between acute angles and obtuse angles?Acute angles are angles whose measure is less than 90 degrees. They are sharp angles that are less than a right angle. On the other hand, obtuse angles are angles whose measure is greater than 90 degrees. They are angles that are greater than a right angle and less than 180 degrees. In other words, obtuse angles are angles that are wider than a right angle but less than a straight angle.
Analysing all the statements given in the question,the corrrect options are
Option 1, since angle 1 and 55 degree share the same vertex.
Option 5, since the sum of angle 1 and 55 degree is 180 degrees being supplementary angles.
Option 6, since the sum of all the interior angles of a triangle is 180 degrees.

The measure of angle is, 62°.
What is Complementary angle?The sum of two or more angle is 90 degree then the angle is called the complementary angle.
We have to given that;
⇒ Supplement of an angle is 6 more than 4 times of its complement.
Now,
Let measure of an angle = x
So, By given condition, we can formulate;
The supplement of an angle = 180 - x
And, The complement an angle = 90 - x
Hence, We get;
⇒ (180 - x) = 6 + 4 (90 - x)
Solve for x as;
⇒ 180 - x = 6 + 360 - 4x
⇒ 4x - x = 366 - 180
⇒ 3x = 186
⇒ x = 62°

What is relation of log and e?
The relationship between the natural logarithm (ln) and the natural exponential (e) is given by the equation ln(x) = e^x. This equation is known as the exponential form of the natural logarithm.
To explain this relationship, let's start with a simple example. Suppose we have a number x, and we want to find its natural logarithm. To do this, we can use the following equation:
ln(x) = e^x
This equation states that the natural logarithm of x is equal to the natural exponential of x. In other words, we can calculate the natural logarithm of x by raising e to the power of x. To illustrate this with an example, suppose we want to calculate the natural logarithm of 10. We can do this using the equation above as follows:
ln(10) = e^10
Now, we can use a calculator to calculate e^10. If we do this, we get the result of 22,366.48. Therefore, the natural logarithm of 10 is equal to 22,366.48.
The relationship between the natural logarithm and the natural exponential is important because it allows us to easily calculate the natural logarithm of any number. All we have to do is raise e to the power of that number, and the result will be the natural logarithm of that number. This is a very useful tool in mathematics and can be used to solve many problems involving logarithms.

We'll begin calculating the value of y. This can be obtained as follow:
10² = y² + 4²
100 = y² + 16
Collect like terms
100 – 16 = y²
84 = y²
Take the square root of both side
y = √84
Finally, we shall determine the value of x. This can be obtained as follow:
y² = x² + 7²
(√84)² = x² + 49
84 = x² + 49
Collect like terms
84 – 49 = x²
35 = x²
Take the square root of both side
x = √35
Answer:
√35
Step-by-step explanation:
10² = y² + 4²
100 = y² + 16
100 – 16 = y²
84 = y²
y = √84
y² = x² + 7²
(√84)² = x² + 49
84 = x² + 49
84 – 49 = x²

Identify the similar triangles in the figure then find the value of X.
A. Write the similarity statement in the form of triangle~triangle.
B. What is the value of X.
Answer:
A. ∆ABD ~ ∆CDE
B. x ≈ 5.3
Step-by-step explanation:
A. The Acute Angle Similarity Theorem states that when an acute angle in one right triangle is congruent to a corresponding acute angle in another, both right triangles are said to be similar to each other.
<B ≅ <D (both are right angles)
<A ≅ C,
Therefore, ∆ABD ~ ∆CDE
B. Since ∆ABD ~ ∆CDE, corresponding sides would be proportional to each other. This means that:
DE/BD = CD/AB
