show me a Graph x=−4.
Answer:
The graph of line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,
Step-by-step explanation:
Given the line
x=−4
The given line x=-4 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-4 is undefined.
As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
The graph of the line x = -4 is also attached below.
The graph indicates that no matter what the value of y is, the x-value remains the same. Hence, the line is vertical with undefined slope,

What is x if n≠m? Please help!
Answer: [tex]x = \frac{mn(q - p)}{n-m}\\\\[/tex]
================================================
Work Shown:
Part 1
[tex]\frac{x-m}{m} + p = \frac{x-n}{n} + q\\\\\frac{x-m}{m} - \frac{x-n}{n} = q - p\\\\\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p\\\\\frac{xn-mn}{mn} - \frac{xm-mn}{mn} = q - p\\\\\frac{xn-mn-(xm-mn)}{mn} = q - p\\\\[/tex]
Part 2
[tex]\frac{xn-mn-xm+mn}{mn} = q - p\\\\\frac{xn-xm}{mn} = q - p\\\\\frac{x(n-m)}{mn} = q - p\\\\x(n-m) = mn(q - p)\\\\x = \frac{mn(q - p)}{n-m} \\\\[/tex]
-------------------------------
Explanations:
There are quite a bit of steps. I decided to break things into two parts.The goal is to get x all by itself on its own side, which is why I subtracted (x-n)/n from both sides in part 1, step 2. I also subtracted p from both sides.Afterward, I gave each fraction the LCD mn. I multiplied top and bottom of the first fraction by n/n. I did a similar operation to the second fraction, but with m instead.From there, we distribute and simplify. The mn terms cancel on the left side numerator (second step of part 2).The n≠m is there to prevent the denominator (n-m) from being zero. We cannot divide by zero.

6.) Giovanni makes $0.75 profit for each cupcake that he sells. He wants to 4 polu
buy a new $10 cupcake tin. He wants to know how many cupcakes will he
need to sell so that he can buy the cupcake tin and still have $35 profit
eft. Which equation can be used to solve this problem?*
Answer:
60
Step-by-step explanation:
you add what he needs to make in total up ten dollars for the cupcake tin and the thirty five dollars for the profit he wants to make then I used the guess and check strategy knowing that 100 cupcakes would make him 75 dollars I worked my way down multiplying 0.75 times 90, 80, 70 and then landed on the answer 60
Which number line represents the solution to 5x ≥ 30?
Answer:
Its B
Step-by-step explanation:
since the symbol has a line underneath its shaded so A & B are left.
the symbol shows > so the point is where the line goes, for this question it goes to the right.
The required number line represents the solution to 5x ≥ 30 is shown in option B.
What is a number line?A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
According to the question, the inequality 5x ≥ 30 can be solved by dividing both sides by 5, which gives x ≥ 6. This means that any number greater than or equal to 6 is a solution to the inequality.
Looking at the number line options, we can see that only the last one correctly represents the solution to the inequality. The line starts at 6 and includes all numbers greater than or equal to 6, which matches the solution x ≥ 6.
Therefore, the correct answer is the number line shown in option B.

Answer:
The answer is B.
Step-by-step explanation:
Learn it yourself kid.
Answer and Step-by-step explanation:
First, look at the inequality. We see the there is a greater than or equal to sign.
That means the graphs can NOT be C or D, since those graphs only apply to inequalities with the greater than or less than sign.
That leaves us with graphs A and B.
We see the y is greater than the value, so anything above the line is filled in.
That means that graph A is the answer. Which means,
Answer choice B, graph A.

Question 5 (5 points)
Answer:
Option 1 is correct i.e.
[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2=\frac{2^6.1^2}{5^2}=\frac{64}{25}[/tex]
Step-by-step explanation:
We need to simplify the expression: [tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2[/tex]
We know that: [tex](a^m)^n= a^{m*n}[/tex] and [tex]a^0=1[/tex]
We would use these exponent laws to solve our question.
First we will apply [tex]a^0=1[/tex]
[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2\\=(\frac{2^3\:\textbf{.}\:1}{5})^2\\[/tex]
Now, we will apply [tex](a^m)^n= a^{m*n}[/tex]
[tex]=\frac{(2^3)^2\:\textbf{.}\:1^2}{5^2}\\=\frac{2^6\:\textbf{.}\:1}{5^2}\\=\frac{64}{25}[/tex]
So, the result is: [tex]\frac{64}{25}[/tex]
Therefore, Option 1 is correct i.e.
[tex](\frac{2^3\:\textbf{.}\:3^0}{5})^2=\frac{2^6.1^2}{5^2}=\frac{64}{25}[/tex]

Lynn has a box of crayons.
4/9 of the crayons are blue
65% of the remaining crayons are red.
The other 14 crayons are yellow.
How many crayons are in the box altogether?
Answer:
There are 72 crayons in the box
Step-by-step explanation:
Fractions
To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.
Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:
[tex]1-\frac{4}{9}=\frac{5}{9}[/tex]
From that portion, 65% are red, or equivalently, 35% are yellow.
We write 35% as a fraction:
[tex]\displaystyle 35\%=\frac{35}{100}=\frac{7}{20}[/tex]
Thus, the portion of yellow crayons is:
[tex]\displaystyle \frac{7}{20}\cdot \frac{5}{9}=\frac{7}{36}[/tex]
This fraction of x crayons is equal to 14, thus:
[tex]\displaystyle x=\frac{14}{\frac{7}{36}}=14\cdot\frac{36}{7}[/tex]
x = 72
There are 72 crayons in the box
