Determine the value(s) for which the rational expression 5x6x is undefined. If there's more than one value, list them separated by a comma, e.g. x=2,3.
Answers
Explanation:
We cannot have zero in the denominator. If x = 0, then the denominator 6x becomes 6x = 6*0 = 0. So we must exclude this from the domain to avoid a division by zero error.
One could argue that the 'x's cancel out when we divide. Yes that's true and [tex]\frac{5x}{6x} = \frac{5}{6}[/tex], but as far as the calculator is concerned, it will not try to simplify the expression (unless it's a specific type of calculator). Instead, the calculator would likely follow the order of operations PEMDAS to try to compute directly. The calculator would hit the stumbling block of dividing by zero and produce "undefined" or "not a number".

The length of the top of a table is 4 m greater than the width. The area is 60m^2. Find the dimensions of the table
Answers
Answer:
Width = 6 m
Length = 10 m
Step-by-step explanation:
Let the width of the table be x meters.
Therefore, length of the table = (x + 4) meters.
[tex]length \times width = Area \\ \\ x(x + 4) = 60 \\ \\ {x}^{2} + 4x - 60 = 0 \\ \\ {x}^{2} + 10x - 6x - 60 = 0 \\ \\ x(x + 10) - 6(x + 10) = 0 \\ \\ (x + 10)(x - 6) = 0 \\ \\ x + 10 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 10 \: \: or \: \: x = 6 \\ \\ \because \: dimensions \: can \: not \: be \: negative \\ \therefore \: x \notin \: 10 \\ \implies \: x = 6 \\ x + 4 = 6 + 4 = 10 \\ width \: of \: table = 6 \: m \\ length \: of \: table = 10 \: m[/tex]

A rectangle is folded by a vertical and horizontal line going through its center, has all the correct lines of reflectional symmetry for the rectangle.
What is reflectional symmetry?A well-balanced proportion in which two images or figures are the same size and shape is referred to as symmetry.
When the same figure is obtained following a transformation in geometry whether it be a reflection or a rotation symmetry has occurred.
An example of a shape with reflection symmetry is a rectangle. A line of reflection that passes through the center of two different sides will always be symmetrical.
There are two symmetry lines in a rectangle.
Each side of the rectangle would match up exactly if the rectangle were folded along each line of symmetry.
Keep in mind that a shape must possess at least one line of symmetry in order to qualify as having reflection symmetry.

Bobby rich dude has $120,000 in his account that pays him 5.5% compounded daily. What amount and how much interest will his money earn in 30-days?
Answers
Answer:
Interest: Amount Gained: $198,000
Final Balance: Amount After 30 days of Interest: $318,000
Step-by-step explanation:
Equation Used to Solve:
120,000 · 0.055 = 120,000 + (xy)
Let x represent 5.5% of 120,000
Let y represent the number of days.
Solving the equation:
120,000 · 0.055 = 6,600
x = 6,600; y = 30
120,000 + (6,600 · 30) = 120,000 + 198,000
120,000 + 198,000 = 318,000

You are building a cube shaped box for your turtle to live in. You want to build your box with side lengths of 24 inches. However, when you finish the box, you find out that it has a volume of 27,000 cubic inches. How many more cubic inches is your box than you had planned? How much bigger are your side lengths than you had originally planned?
Answers
Answer: The box is 13,176 cubic inches larger than originally planned.
The side lengths turned out to be 6 inches longer than the 24 inches originally planned.
Step-by-step explanation:
To find the intended volume, "cube" 24 (24×24×24)
[tex]24^{3}= 13824[/tex]
To find the difference, subtract 13,824 from 27,000
27000 - 13824 = 13176
To find the actual side lengths of the box that was built take the cube root of 27000.
[tex]\sqrt[3]{27000}=30[/tex]
To find out how much longer, subtract 24 from 30.
30 - 24 = 6

4. The value of y is directly proportional to the value of x. If y = 45 when x = 180, what is the value of y when x = 80?
Answers
Answer:
y=8⇒8=24x
x=24/8=3
Step-by-step explanation:
The value of y when x = 80 is 20.
It is required to find the value of y.
What is arithmetic?Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.
Solution:
"Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX
"K" is the constant of proportionality and must be determined from the initial information.
According to given question we have,
If Y = 45 when X=180
It means
45 = 180K
K = 45/180
K = 0.25
Now that we know the value of K, we can use it to calculate the value of Y when X=80
Y = (0.25)(80)
Y=20
Therefore, the value of y when x = 80 is 20.

The equation 7(x − 4) = 8(x + 8) has one solution. Which of the following best explains why?
A.
The x-terms are the same, but the constant terms are different.
B.
The x-terms are different, and the constant terms are different.
C.
The x-terms are the same, and the constant terms are the same.
D.
The x-terms are different, but the constant terms are the same.
Answers
Answer:
C. The x-terms are the same, and the constant terms are the same.
Step-by-step explanation:
Solve for x:
7 (x - 4) = 8 (x + 8)
Hint: | Write the linear polynomial on the left-hand side in standard form.
Expand out terms of the left hand side:
7 x - 28 = 8 (x + 8)
Hint: | Write the linear polynomial on the left-hand side in standard form.
Expand out terms of the right hand side:
7 x - 28 = 8 x + 64
Hint: | Move terms with x to the left-hand side.
Subtract 8 x from both sides:
(7 x - 8 x) - 28 = (8 x - 8 x) + 64
Hint: | Combine like terms in 7 x - 8 x.
7 x - 8 x = -x:
-x - 28 = (8 x - 8 x) + 64
Hint: | Look for the difference of two identical terms.
8 x - 8 x = 0:
-x - 28 = 64
Hint: | Isolate terms with x to the left-hand side.
Add 28 to both sides:
(28 - 28) - x = 28 + 64
Hint: | Look for the difference of two identical terms.
28 - 28 = 0:
-x = 64 + 28
Hint: | Evaluate 64 + 28.
64 + 28 = 92:
-x = 92
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of -x = 92 by -1:
(-x)/(-1) = -92
Hint: | Any nonzero number divided by itself is one.
(-1)/(-1) = 1:
Answer: x = -92
