Find the slope of a line parallel to 2x – 3y = 5 ?a. -2/3b. 2/3C. -3/2d. 3/2
Answer
Slope of the line is 2/3
Step-by-step explanation:
Given the slope-intercept equation
2x - 3y = 5
The standard form of the slope-intercept equation is
y = mx + b
where m = slope of the line
b = intercept of the y-axis
Rearrange the above equation
2x - 3y = 5
-3y = 5 - 2x
-3y = -2x + 5
Divide through by -3
-3y/-3 =-2x/-3 + (5/-3)
y = 2x/3 - 5/3
Hence, the slope of the line is 2/3
10) Find the product 5(cos 40° + i sin 40°) and 8 (cos 95° + i sin 95°). Write your answer in rectangular form.
We may multiply the magnitudes and add the angles to determine the product of the complex numbers 5 (cos 40° + i sin 40°) and 8 (cos 95° + i sin 95°).
The magnitudes are first multiplied: 5 x 8 = 40.
The angles are then added: 40° + 95° = 135°.
As a result, the product can be expressed as 40(cos 135° + i sin 135°) in polar form.
We can apply the following trigonometric identities to transform this into rectangular form:Sin() = sin(135°) = 2/2 cos() = cos(135°) = -2/2
Therefore, the rectangle product is 40 * (- 2/2 + i 2/2).
To further simplify, we have: -202 + 20i2.
In rectangular form, the complex numbers 5 (cos 40° + i sin 40°) and 8 (cos 95° + i sin 95°) are therefore multiplied by each other to provide -202 + 20i2.

Summarize the five methods used in this lesson to prove that two lines are parallel.
The five methods used to prove that two lines are parallel are: Corresponding angles theorem, Alternate interior angles theorem, Converse of corresponding angles theorem, Converse of alternate interior angles theorem, Converse of the same-side interior angles theorem.
To prove that two lines are parallel, we can use various methods. The corresponding angles theorem states that if the corresponding angles formed by a transversal and two lines are congruent, then the lines are parallel. The alternate interior angles theorem states that if the alternate interior angles formed by a transversal and two lines are congruent, then the lines are parallel. The converse of corresponding angles theorem and converse of alternate interior angles theorem state that if the lines are parallel, then the corresponding angles or alternate interior angles are congruent, respectively. The converse of the same-side interior angles theorem states that if the same-side interior angles formed by a transversal and two lines are supplementary, then the lines are parallel.
The third method is the converse of corresponding angles theorem. This converse states that if the lines are parallel, then the corresponding angles are congruent. The fourth method is the converse of alternate interior angles theorem. This converse states that if the lines are parallel, then the alternate interior angles are congruent. The fifth and final method is the converse of the same-side interior angles theorem. This converse states that if the same-side interior angles formed by a transversal and two lines are supplementary, then the lines are parallel.
These five methods provide different ways to prove that two lines are parallel. By using these theorems and their converses, we can confidently determine if two lines are parallel or not.

Question: Write the standard form equation of the circle given the center of (-1,0) and the circumference of 8π. Show all work using the equation editor to calculate the missing pieces of the equation.
The standard form equation of the circle with the center (-1, 0) and circumference 8π is (x + 1)² + y² = 16.
To write the standard form equation of a circle, we use the formula:
(x - h)² + (y - k)² = r²
where (h, k) represents the center of the circle, and r represents the radius.
Given the center of the circle as (-1, 0) and the circumference of 8π, we can find the radius using the formula for circumference:
Circumference = 2πr
8π = 2πr
Dividing both sides by 2π:
4 = r
Now we have the center (-1, 0) and the radius r = 4. Plugging these values into the standard form equation, we get:
(x - (-1))² + (y - 0)² = 4²
Simplifying:
(x + 1)² + y² = 16
Therefore, the standard form equation of the circle with the center (-1, 0) and circumference 8π is (x + 1)² + y² = 16.

The school population for a certain school is predicted to increase by 60 students per year for the next 13 years. If the current enrollment is 900 students, what will the enrollment be after 13 years?
Answer:
1,680
Step-by-step explanation:
If the population is increasing by 60 for the next 13 years, we must multiply 60 and 13 to get 780.
Then, we just add 780 to the original population to get 1,680!
The enrollment after 13 years will be 1680.
We have a whose school population is predicted to increase by 60 students per year for the next 13 years. Current enrollment in that school is 900 students.
We have to determine the enrollment be after 13 years.
Starting from x, if the bacteria count rises by 5 every second, then determine the formula to calculate the bacteria count after 30 seconds.Initial count = x
Count increasing per second = 5
Assume that the bacteria count after t seconds is y. Then -
y = x + 5t
for t = 30 ↔ y = 150 + x
According to question, we have -
Initial population P(i) = 900
Assume the population after the n years is P(n).
Number of students enrolled in 'n' years will be = 60n
Therefore, the following equation can be used -
P(n) = P(i) + 60n
For n = 13 years
P(13) = 900 + 60 x 13 = 900 + 780 = 1680
Hence, the enrollment after 13 years will be 1680.

What are the correct values of a, b, c, d, and e?
a 16, b = 29, c = 22, d = 30, e = 24
a = 29, b = 16, c = 30, d = 22, e = 24
a 16, b = 29, c = 24, d = 22, e = 30
H
a = 29, b = 16, c = 24, d = 30, e = 22
The correct values for a, b, c, d, and e are a = 16, b = 29, c = 24, d = 22, and e = 30 for group of 75 students on asking whether they like Algebra or Geometry.
For the values of a, b, c, d, and e, we can use the information provided in the table. Let's break it down step-by-step:
We are given that a total of 75 math students were surveyed. Therefore, the total number of students should be equal to the sum of the students who like algebra, the students who like geometry, and the students who do not like either subject.
75 = 45 (Likes Algebra) + 53 (Likes Geometry) + 6 (Does Not Like Either)
Simplifying this equation, we have:
75 = 98 + 6
75 = 104
This equation is incorrect, so we can eliminate options c and d.
Now, let's look at the information given for the students who do not like geometry. We know that a + b = 6, where a represents the number of students who like algebra and do not like geometry, and b represents the number of students who do not like algebra and do not like geometry.
Using the correct values for a and b, we have:
16 + b = 6
b = 6 - 16
b = -10
Since we can't have a negative value for the number of students, option a is also incorrect.
The remaining option is option e, where a = 29, b = 16, c = 24, d = 22, and e = 30. Let's verify if these values satisfy all the given conditions.
Likes Algebra: a + c = 29 + 24 = 53 (Matches the given value)
Does Not Like Algebra: b + d = 16 + 22 = 38 (Matches the given value)
Likes Geometry: c + d = 24 + 22 = 46 (Matches the given value)
Does Not Like Geometry: b + e = 16 + 30 = 46 (Matches the given value)
All the values satisfy the given conditions, confirming that option e (a = 29, b = 16, c = 24, d = 22, and e = 30) is the correct answer.

The simplified form of (5x + 4y)(2x - y) is \(10x^2+3xy-4y^2\)
d. (3x + 7)(3x – 7)
Using the formula: \((a+b)(a-b) = a^2-b^2\)
\(= (3x)^2-(7)^2\\= 9x^2-49\)
The simplified form of (3x + 7)(3x – 7) is \(9x^2-49\)
e. (t + 2) – (4t +9) – t

explain each step to this question and show full working out to make sure the answer is correct: Amy, John, and Emily each earn the same monthly salary. Each month, Amy saves 20% of her salary and spends the rest of her salary. John spends 2/5 of his salary and saves the rest of his salary. The amount of salary Emily saves to the amount of salary she spends is 5:8. Workout who saves the most of their salary each month.
can you do this in 10 min or less, please
Answer:
To compare who saves the most of their salary each month among Amy, John, and Emily, we need to calculate the amount of salary each person saves.
Let's assume that the monthly salary of each person is 'S'. Then we can calculate the amount saved by each person as follows:
Amy:
Amount saved = 20% of S = 0.2S
Amount spent = S - 0.2S = 0.8S
John:
Amount spent = 2/5 of S = (2/5)S
Amount saved = S - (2/5)S = (3/5)S
Emily:
Let's assume that Emily saves '5x' and spends '8x' of her monthly salary.
Then, according to the question, we have:
Amount saved = 5x
Amount spent = 8x
We know that the ratio of the amount saved to the amount spent is 5:8, so we can write:
Amount saved / Amount spent = 5/8
Substituting the values of amount saved and amount spent, we get:
5x / 8x = 5/8
5x = (5/8) x 8x
5x = 5x
Therefore, the ratio of amount saved to amount spent is equal to 5:8. This means that Emily saves 5/13 of her monthly salary and spends 8/13 of her monthly salary.
So, the amount saved by each person is:
Amy: 0.2S
John: (3/5)S
Emily: 5/13 of S
Now, we need to compare these amounts to find out who saves the most.
To compare these amounts, we can write them in terms of a common denominator:
Amy: 0.2S
John: (3/5)S = (0.6)S
Emily: (5/13)S = (0.3846)S (approx.)
Therefore, we see that John saves the most of his salary each month, followed by Amy and then Emily.
Working out:
Let's assume that each person earns $1000 per month.
Amy:
Amount saved = 20% of $1000 = $200
Amount spent = $800
John:
Amount spent = 2/5 of $1000 = $400
Amount saved = $1000 - $400 = $600
Emily:
Let's assume that Emily saves $5x and spends $8x of her monthly salary.
Then, we have:
Amount saved = $5x
Amount spent = $8x
We know that the ratio of the amount saved to the amount spent is 5:8, so we can write:
$5x / $8x = 5/8
Solving for x, we get:
x = 8/13
Substituting the value of x, we get:
Amount saved = $5 x (8/13) x $1000 = $384.62 (approx.)
Amount spent = $8 x (8/13) x $1000 = $615.38 (approx.)
Therefore, we see that John saves the most of his salary each month, followed by Amy and then Emily.
