solve for linear inequality of x - 1 ≥ 4 + x
Answers
\(\huge\bf{ANSWER:}\)
\(\huge\mathrm{No\:solution.}\checkmark\)
\(\huge\bf{SOLUTION}:\)
Hey there, hope you are having a wonderful day! :)
Let's solve this inequality.
First of all, let's move all the numbers to the right, using the \(\bf{\underline{opposite\:\:operation\:}\):
\(\longmapsto\)\(\sf{x-1\geq 4+x\)
\(\longmapsto\sf{x\geq 4+x+1\)
\(\longmapsto\sf{x\geq x+5\)
Now, let's move the variables to the left:
\(\longmapsto\sf{x-x\geq 5\)
\(\longmapsto\sf{0\geq 5\)
Now, as you can see, we ended up with a false statement. 0 is NOT greater than 5.
Thus, there are no values of x that make the inequality true, and the inequality has
\(\bold{No\:solutions.}\)
Hope you find it helpful.
Feel free to ask if you have any doubts.

Simplify (-4+7i)+(-3-8i)
Answers
The simplified form of (-4 + 7i) + (-3 - 8i) is -7 - i.
To simplify the expression (-4 + 7i) + (-3 - 8i), we combine the real parts (the terms without 'i') and the imaginary parts (the terms with 'i') separately.
First, let's simplify the real parts:
-4 + (-3) = -7
Next, let's simplify the imaginary parts:
7i + (-8i) = 7i - 8i = -i
Now, we combine the simplified real and imaginary parts:
-7 + (-i) = -7 - i
Therefore, the simplified form of (-4 + 7i) + (-3 - 8i) is -7 - i.

Brian has earned 65%, 80% and 92% on his three pre-final exams. These exams are not weighed equally: the lowest counts for only 20% of his overall grade, while the other two count for 25% each. If the final exam is the remainder of the overall grade and there are no opportunities for extra credit, what is the highest grade Brian can earn in the class? Express your answer to the nearest whole percent.
Answers
Answer:
89.25%
Step-by-step explanation:
65 is the lowest so it only counts for 20% of the grade
65*0.2=16.25
80*0.25=20
92*0.25=23
There is 30% left and 100% is the highest score
100*0.3=30
16.25+20+23+30=89.25
Answer:
86%
Step-by-step explanation:
From the information give:
Exam 1
Exam result = 65%
Overall grade weighting = 20%
⇒ Credit = 65% of 20% = 0.65 × 0.2 = 0.13 = 13%
Exam 2
Exam result = 80%
Overall grade weighting = 25%
⇒ Credit = 80% of 25% = 0.8 × 0.25 = 0.2 = 20%
Exam 3
Exam result = 92%
Overall grade weighting = 25%
⇒ Credit = 92% of 25% = 0.92 × 0.25 = 0.23 = 23%
Final Exam
The highest grade Brian can earn = 100%
Overall grade weighting = 100% - 20% - 25% - 25% = 30%
⇒ Credit = 100% of 30% = 1 × 30% = 30%
Highest potential class grade
Sum of each exam credit:
⇒ 13% + 20% + 23% + 30% = 86%
Therefore, the highest grade possible that Brian can earn in the class is 86%.

What is domain and range
Answers
The domain of the relation S is the set of all x-values from the ordered pairs in the relation. In this case, the given ordered pairs are (3, p), (3, 0), (4, g), and (1, 4).
To find the domain, we collect all the unique x-values from these ordered pairs.
From the given pairs, we have x = 3, x = 4, and x = 1. However, note that (3, p) and (3, 0) have the same x-value of 3. When considering the domain, we only need to list unique x-values.
Therefore, the domain of the relation S can be expressed as:
domain = {1, 3, 4}
Moving on to the range of the relation S, it refers to the set of all y-values from the ordered pairs.
From the given pairs, we have y = p, y = 0, y = g, and y = 4. Similarly, we need to consider only unique y-values when determining the range.
Thus, the range of the relation S can be expressed as:
range = {0, 4, g, p}
It's important to note that the specific values of g and p are not given in the question. So, in the range, g and p are considered as distinct symbols representing unknown values.

EE 21-7 Jonick Company has sales of $740,000, and the break-even point in sales dollars is $547,600. Determine the company’s margin of safety as a percent of current sales.
Answers
Answer: Jonick Company's margin of safety as a percentage of current sales is 26.05%.
Step-by-step explanation: To find the margin of safety as a percentage of current sales, we need to first calculate the margin of safety, which is the amount of sales above the break-even point:
Margin of safety = Actual sales - Break-even point
We know that actual sales are $740,000 and the break-even point is $547,600, so:
Margin of safety = $740,000 - $547,600
Margin of safety = $192,400
Now that we know the margin of safety, we can calculate it as a percentage of current sales:
Margin of safety % = (Margin of safety / Actual sales) x 100
Plugging in the numbers, we get:
Margin of safety % = ($192,400 / $740,000) x 100
Margin of safety % = 26.05%
Therefore, Jonick Company's margin of safety as a percentage of current sales is 26.05%. This means that sales can drop by 26.05% before the company starts to incur losses.

Answers
The equation of the line is y = -1/2 + 13/2.
The point is (3, 5).
An equation of line is x + 2y = 5.
To determine the slope intercept form of the equation using the point and line we first determine the slope of the equation from the given line.
Convert the equation of line in slope intercept form.
x + 2y = 5
Subtract x on both side, we get
2y = -x + 5
Divide by 2 on both side, we get
y = -1/2 x + 5
On comparing with y = mx + c, where m is slope, we get
m = -1/2
Now the equation of the line is;
y - y₁ = m(x - x₁)
y - 5 = -1/2(x - 3)
Simplify the bracket
y - 5 = -1/2x + 3/2
Add 5 on both side, we get
