how do we graph linear equations short answer
Answers
Answer
To graph linear equations, the best approach is to use the intercepts to obtain two points on the line in order to connect.
The two intercepts include the x and y intercepts.
So, once, the two intercepts are obtained and then connected, the line is obtained.

Assuming the figure is a parallelogram,
Also,
But 115 = (6x+11) + (4x+6)
115 = 6x - 11 + 4x + 6
115 = 6x + 4x - 11 + 6
115 = 10x - 5
10x = 115 + 5
10x = 120

The differentiation of the given function f(x) = eˣ+6 is eˣ
What is differentiation?The derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus.
Given is function f(x) = eˣ+6, we need to find the derivative of this function,
f(x) = eˣ+6
f'(x) = d / dx (eˣ+6)
= d(eˣ)/dx + d(6)/dx
Since, 6 is a constant and derivative of a constant is zero,
d(eˣ)/dx + d(6)/dx = d(eˣ)/dx + 0
Now, when we differentiate eˣ, we get eˣ itself,
Therefore,
d(eˣ)/dx = eˣ
Therefore, the differentiation of the given function f(x) = eˣ+6 is eˣ

Marianne had 128 brood cows. She lost 2 cows and calves during calving and 3 calves were born dead. She had 4 cows that did not calve.
a. What percent of the cows was lost? Express your answer to the nearest tenth of a percent.
b. How many calves does she have?
c. What percent of the cows have a calf at their side? Express your answer to the nearest tenth of a percent.
Part a
total original cows=128 ------> represent 100%
so
Applying proportion
Find out how much percentage represent 2 cows
100/128=x/2
solve for x
x=(100/128)*2
x=1.6%
Part b
total cows=128-2=126
total calves=126-3-4=119 calves
Part c
total cows=126
total cows that have a calf at their side=119
applying proportion
100/126=x/119
solve for x
x=(100/126)*119
x=94.4%

It would take 21 weeks for the population to surpass 16,000.
The insect population P in a certain area fluctuates with the seasons and is estimated by the function P = 15,000 + 2500 sin(πt/52), where t is given in weeks.
For the population to surpass 16,000, we can set up the following equation:
15,000 + 2500 sin(πt/52) = 16,000
Subtracting 15,000 from both sides, we get:
2500 sin(πt/52) = 1000
Dividing both sides by 2500, we get:
sin(πt/52) = 0.4
We know that sin(πt/52) is positive when t is between 0 and 52 and between 104 and 156 since sine is positive in the first and second quadrants. Therefore, we can write:
πt/52 = sin⁻¹(0.4)
Multiplying both sides by 52/π, we get:
t = (52/π) sin⁻¹(0.4)
Using a calculator, we can evaluate sin⁻¹(0.4) to be approximately 0.4115 radians.
t = (52/π) (0.4115)
t = 21.02
Therefore, it would take 21 weeks for the population to surpass 16,000.

Answers
Answer:
20 blogs
Step-by-step explanation:
Step 1: Determine the proportion of pop culture blogs:
First, we need to determine the proportion of pop culture blogs already written. We can do this by dividing the number of pop culture blogs already written by the total number of blogs written:
The proportion of pop culture bloggers = Number of pop culture bloggers / Total number of bloggers
Proportion = 26 / (20 + 26 + 7 + 12)
Proportion = 26 / 65
Proportion = 0.4
Step 2: Multiply the proportion of pop culture blogs by the number of upcoming blogs:
To determine the expected number of pop culture blogs that will be written given the data, we can multiply the proportion of pop culture blogs already written by the number of upcoming blogs:
Expected number of pop culture blogs = proportion of pop culture blogs * number of upcoming blogs
Expected number = 0.4 * 50
Expected number = 20
Thus, you should expect 20 pop culture blogs to be written given the data.
Desmond's monthly Netflix subscription costs $14.
If he charges it to his credit card each month for 7
months without making any payments, what will
his debt be?
Explain how you would solve this problem.
What is the answer?
Answers
Answer:
Desmond has a debt of $98.
Step-by-step explanation:
We are given that Desmond has a monthly Netflix subscription that charges him $14. Since it is a monthly subscription, it is a recurring charge.
We are also given that he does not make payments for 7 months. This means that the subscription is recurring for seven months.
Therefore, if he is charged $14 monthly and is charged that for 7 months, we can say that he is charged $14 seven times.
Therefore, we can create an equation that solved how much his debt would be based on this information.
\(\displaystyle14(7) = c\\\\14\times7=98\\\\c = 98\)
Therefore, Desmond has a debt of $98.

The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet)
What is elevation?
The elevation is the height of an object or point above a given reference point, usually sea level. It is often used to describe the height or altitude of a geographic location, such as a mountain peak or a city, and is commonly measured in feet or meters.
In the context of elevation, | -7 | feet would mean the vertical distance between the point at -7 feet and sea level (0 feet).
The vertical distance between two points is calculated by taking the absolute value of the difference between their elevations. So, in this case, the absolute value of -7 is 7, which means the point is 7 feet below sea level.
The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet).

Galaxy distance is 118 mpc.
Given:
Suppose a distant galaxy has a recessional velocity of 8254 km/s. What is its distance given that the hubble constant is 70 km/s/mpc.
According to hubble's law:
v = \(H_0\\\) * D
where
v = velocity = 8254
\(H_0\\\) = hubble constant = 70
D = v/\(H_0\\\)
= 8254/70
= 4127/35
= 117.91

The diameter of ball bearings produced in a manufacturing process can be explained using a uniform distribution over the interval 3.5 to 5.5 millimeters. What is the probability that a randomly selected ball bearing has a diameter greater than 4.4 millimeters
Answers
Answer:
The probability that a randomly selected ball bearing has a diameter greater than 4.4 millimeters is P=0.55.
Step-by-step explanation:
A uniform distribution have a constant probability for each value within the interval, in this case 3.5 to 5.5 mm., and 0 for any value outside this interval.
We can calculate the probability that we have a diameter of X=4.4 or greater as:
\(P(X>4.4)=\dfrac{Max-X}{Max-Min}=\dfrac{5.5-4.4}{5.5-3.5}=\dfrac{1.1}{2}=0.55\)
The probability that a randomly selected ball bearing has a diameter greater than 4.4 millimeters is P=0.55.

Answers
Answer:

Step-by-step explanation:
Count all letters and all vowels then divide vowels by letters
The probability that a vowel is randomly selected in the experiment of selecting a letter from the phrase "Sean wants to eat at Olive Garden", is 4/9.
What is the probability of an event in an experiment?The probability of any event suppose A, in an experiment is given as:
P(A) = n/S,
where P(A) is the probability of event A, n is the number of favorable outcomes to event A in the experiment, and S is the total number of outcomes in the experiment.
How to solve the given question?In the question, we are given an experiment of selecting a letter from the phrase "Sean wants to eat at Olive Garden".
We are asked to find the probability that the selected letter is a vowel.
Let the event of selecting a vowel from the experiment of selecting a letter from the phrase "Sean wants to eat at Olive Garden" be A.
We can calculate the probability of event A by the formula:
P(A) = n/S,
where P(A) is the probability of event A, n is the number of favorable outcomes to event A in the experiment, and S is the total number of outcomes in the experiment.
The number of outcomes favorable to event A (n) = 12 (Number of vowels in the phrase)
The total number of outcomes in the experiment (S) = 27 (Number of letters in the phrase).
Now, we can find the probability of event A as:
P(A) = 12/27 = 4/9
∴ The probability that a vowel is randomly selected in the experiment of selecting a letter from the phrase "Sean wants to eat at Olive Garden", is 4/9.
