Only A
Only B
Both A and B
Neither A nor B
Answer:
Both A and B
Step-by-step explanation:
For functions you are just trying to make sure all the x's are different.
So let's look at A: The x's there are all different so it is a function
Now let's look at B: The x's there are all different so it is a function.
Both A and B
Solve the equation below: (X+4)/6x=1/x
A. X=2
B. X=0,2
C. X=-2
D. X=0,-2
For this case we must solve the following equation:
[tex]\frac {x + 4} {6x} = \frac {1} {x}[/tex]
We multiply by "6x" on both sides of the equation:
[tex]x + 4 = \frac {6x} {x}\\x + 4 = 6[/tex]
Subtracting 4 on both sides of the equation:
[tex]x = 6-4\\x = 2[/tex]
Thus, the result of the equation is 2.

EXPLANATION
The given rational expression is
[tex] \frac{ - 12 {x}^{4} }{ {x}^{4} + 8 {x}^{5} } [/tex]
We factor to get;
[tex]\frac{ - 12 {x}^{4} }{ {x}^{4} (1+ 8 {x}) } [/tex]
We can see that:
[tex] {x}^{4} [/tex]

There are four accent walls that need to be painted: cafeteria, gym, auditorium, and entrance. The art class is going to paint either a forest or an ocean nature scene on one of them. What is the probability that the ocean scene is painted in the gym?
Answer:
12.5%
Step-by-step explanation:
There are 4 walls to choose from, and 2 scenes to choose from. So the number of combinations is 2×4=8. One of those is the ocean scene on the gym wall. So the probability is:
P = 1/8
P = 12.5%

Which best describes the dimensions of a line?
A line can be described as a one-dimensional element with length greater than its width. It is formed by connecting two or more points and can be used to create shapes, define forms, and indicate motion.
Explanation:A line can be described as a point in motion. It is the simplest visual element and is characterized by its length being greater than its width. When two or more points are connected, a line is formed. For example, when you draw a line segment connecting two points on a paper, you create a line. Lines can be used to create shapes, define forms, and indicate motion. It is important to note that a line is one-dimensional and has no width or depth.

Two roots of a 3-degree polynomial equation are 5 and -5. Which of the following cannot be the third root of the equation?
5
5i
0
-5
-5i
Answer:
5i, -5i
Step-by-step explanation:
None 5i nor -5i could be a third root of the polynomial because if we had a complex root then by the complex conjugate root theorem, their conjugate would be a fourth root, while the polynomial which is a 3-degree polynomial can only have three roots according to the Fundamental Theorem of Algebra, which states that the number of roots of the polynomial is equal to the degree of the polynomial.
In other words, for example, if the third root was 5i then its conjugate -5i should be another root according to the complex conjugate root theorem; so we would end with four roots when we are only allowed -by the Fundamental Theorem of Algebra- to have three roots since it is a 3-degree polynomial. The same reasoning applies for -5i whose conjugate is precisely 5i.
The other numbers are real numbers, so any of them can be a third root. Notice that it does not matter if the third root is again 5 or -5 since the real roots can be repeated (multiplicity greater than 1).
Which of the following is closest to 32.9 x 7.5?
A:232
B:259
C:220
D:265
Answer:
B. 259
Step-by-step explanation:
32.9 × 7.5 = 246.75
Therefore, the number closest to 246.75 is 259
PLEASE DO MARK ME AS BRAINLIEST UWU
The closest number is B. 259
To find the answer to this question, you need to multiply 32.9 by 7.5. The option that the product of those two numbers is closest to, is the answer.
= 32.9 x 7.5
= 246.75
= 247 rounded off
This number is closest to 259 as the difference between them is only:
= 259 - 247
= 12
The other options are wrong because:
= 247 - 232
= 15
= 247 - 220
= 27
= 265 - 247
= 18
The closest number is therefore 259.

If two angles are supplementary and one of the angles measures 62°, what is the measure of the other angle?
28°
38°
118°
128°
Answer:
118°
Step-by-step explanation:
Supplementary angles sum to 180°
let x be one of the supplementary angles, then
x + 62 = 180 ( subtract 62 from both sides )
x = 118°
The measure of the supplementary angles are 62° and 118°
What are Supplementary and Complementary Angles?Supplementary angles are two angles that have a sum of 180°.
Complementary angles are two angles that have a sum of 90°.
Given data ,
Let the sum of angles be represented as A
Now , let the first angle be represented as p
And , the value of p = 62°
Let the second angle be represented as q
Now , the value of q = q
For supplementary angles , the sum of the angles is 180°
So , on simplifying , we get
A = p + q = 180°
62° + q = 180°
Subtracting 62° on both sides of the equation , we get
q = 180° - 62°
q = 118°
Hence , the measure of the supplementary angles are 62° and 118° respectively

What is the slope of OG?
Answer:
-5/1
Step-by-step explanation:
Answer: Second option.
Step-by-step explanation:
You can calculate the slope of the line with the following formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
You know the point G(1,-5) and the point O(0,0), then, you can identify that:
[tex]y_2=-5\\y_1=0\\x_2=1\\x_1=0[/tex]
Now you need to substitute these values into the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex], then the slope of OG is:
[tex]m=\frac{-5-0}{1-0}\\\\m=\frac{-5}{1}\\\\m=-5[/tex]
This matches with the second option.
If you have an average 90. Give two numbers other than 90 that would make the average 90
Answer:
The numbers 180 and 0 would make the average 90
Step-by-step explanation:
we know that
To find the average of two numbers, add the numbers and then divide by two.
Let
x ----> one number
y ----> the other number
The average is equal to
(x+y)/2
For x=180 and y=0
the average is equal to
(180+0)/2=90
therefore
The numbers 180 and 0 would make the average 90

What is the volume of the cone with diameter 4 ft and height 4 ft? Round to the nearest cubic foot.
Answer:
V = 67.0206 m3
Step-by-step explanation:
Answer: [tex]17ft^3[/tex]
Step-by-step explanation:
The volume of a cone can be calculated with the following formula:
[tex]V_{(cone)}=\frac{1}{3}\pi r^2h[/tex]
Where "r" is the radius and "h" is the height.
The radius is half the diameter, then "r" is:
[tex]r=\frac{4ft}{2}\\\\r=2ft[/tex]
Since we know that radius and the height, we can substitute them into the formula.
The volume of the cone to the nearest cubic foot is:
[tex]V_{(cone)}=\frac{1}{3}\pi (2ft)^2(4ft)[/tex]
[tex]V_{(cone)}=17ft^3[/tex]
Alex completed 7 homework problems in class. The function p(m) relates the
time (in minutes) Alex spent on his homework at home to the total number of
problems he completed. The input is the number of minutes worked. The
output is the number of problems completed.
p(m)=m/4+7
Which equation represents the inverse function m(p), which uses problems
completed as the input and gives minutes worked as the output?
The answer is:
D. [tex]m(p)=4p-28[/tex]
Why?Inversing a function consists of switching the function (name) and the variable, so, where we have the variable (m for this case) we should rewrite it as the function (p(m)), and then, isolate the function in order to know the inverse function.
So, we are given the function:
[tex]p(m)=\frac{m}{4}+7[/tex]
We know that:
[tex]p(m)^{-1}=m(p)[/tex]
Then, rewriting and calculating, we have:
[tex]p(m)=\frac{m}{4}+7[/tex]
[tex]p=\frac{m(p)}{4}+7\\\\p-7=\frac{m(p)}{4}\\\\m(p)=(p-7)*4=4p-28[/tex]
Hence, we have that the answer is:
D. [tex]m(p)=4p-28[/tex]
Have a nice day!
at 6 am, an online company has sold 120 items that day. If the company sells an average of 30 items per hour for the remainder of the day , write an expression to represent the number of items that were sold n after 6 am
The expression to represent the number of items this online company sold n hours after 6am is 120 + 30n. Since the company had already sold 120 items at 6am, and then sells an average of 30 items every hour, the overall quantity of items sold is expressed by this linear formula.
Explanation:This is a problem related to linear functions, as the company's rate of sales is constant throughout the day. We are given the company sold 120 items at 6 am, which is our starting condition or 'y-intercept'. Then, we know the company sells an average of 30 items per hour, our rate or 'slope', for the rest of the day.
Therefore, the expression to represent the number of items sold n hours after 6 am is 120 + 30n. Here, 120 represents the number of items sold by 6 am, 30 is the average rate at which items are sold per hour, and n is the number of hours after 6 am.

The expression to represent the total number of items sold n hours after 6 am is 120 + 30n, where 120 is the initial amount at 6 am, and 30n is the number of items sold per hour after 6 am.
Explanation:The question involves a linear equation to find the number of items sold by a company n hours after 6 am. Given that the company has sold 120 items by 6 am, and that it sells an average of 30 items per hour for the rest of the day, we represent this scenario with an expression. This can be expressed as 120 + 30n, where n represents the number of hours passed after 6 am.
This equation is made up of two parts: 120 represents the initial number of items sold by the company by 6 am, and 30n represents the number of items the company sells per hour (30) multiplied by the number of hours passed after 6 am (n). Hence, the total number of items sold after n hours will be the sum of these two values.

Vanesa earns a base salary of $400.00 every week with an additional 5% commission on everything she sells. Vanessa sold $1650.00 worth of items last week.
What was Vanessa’s total pay last week?
Answer:
$482.50
Step-by-step explanation:
x=1650×5/100
x=16.5×5
x=82.50
400+82.5=482.5
Answer:
482.50
Step-by-step explanation:
Her base is 400. If she sells nothing, that's her take home.
Take home = 400 + 5% of what she sells.
Take home = 400 + (5/100) * 1650
Take home = 400 + (0.05) * 1650
Take home = 400 + 82.50
Take home = 482.50
the set of ordered pairs represented by the graph below can be described as which of the following
a relation only
a function only
both a relation and function
neither a relation or function
ANSWER
a relation only
EXPLANATION
The given graph shown in the attachment represents only a relation and not a function.
The reason is that, a vertical line drawn across this graph will intersect this graph at more than one point.
Since the graph fails to pass the vertical line test, the ordered pair represented by this graph represents a relation only.
Answer: First option.
Step-by-step explanation:
By definition, a relation is a function if each input value (value of "x") has only one output value (value of "y").
In the figure you can observe that each x-coordinate has more than one y-coordinate. Then, since each input value (value of "x") does not have only one output value (value of "y"), you can say that it is not a function, but a relation only.
Therefore, the conclusion is:
The set of ordered pairs represented by the graph, can be described as a relation only.
