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.
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

Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in slope-intercept form (y = mx + b) with the values of m and b given as decimals, rounded to the nearest hundredth if necessary.
y = 2x ; (4, −4)
Answer:
y = -0.5x -2
Step-by-step explanation:
if two lines are perpendicular, their product equals -1
_________________________________________
let the equation of required line be
y = mx + b as given in the problem to be slope intercept form
m = slope
given line
y = 2x
it is also in y = mx + b , comparing this with y =2x
m = 2 and b =0
now
as product of two perpendicular lines = -1
m*2 = -1
thus
m = -1/2 = -0.5
thus,
slope of required line is -0.5
in y = mx + b
m = -0.5
thus,
y = -0.5x + b
given that this line passes through(4,-4)
putting y = -4 and x = 4 in this equation we can find value of b
-4 = -0.5*4 + b
-4 = -2 + b
=> -4 + 2 = b
thus, b = -2
Thus, slope intercept form of equation is y = -0.5x -2

Answer:
14(3x-1) / 5x^2 (3x+ 1)
Step-by-step explanation:
Please let me know if I gloss over something you don't understand
1) First simplify the complex fraction:
This can be written as
18x-6/ 15x + 5 * 21x^2 / 9x^5
which can be simplified to
18x-6/ 15x + 5 * 7/ 3x^3
which can be written as
(18x-6) * 7 / 3x^3 (15x+ 5)
2)
factor 3 from the top of the expression
3(6x-2) * 7 / 3x^3 (15x + 5)
3)
reduce the fraction with 3
3(6x-2) * 7 / 3x^3 (15x + 5)
(6x-2) * 7 / x^3 (15x + 5)
4)
Distribute 7 through the parenthesis on the top
42x-14/ x^ 3 (15x+ 5)
5)
Distribute x^3 through the parenthesis on the bottom
42x-14/ 15x^4 + 5x^3
6)
factor 14 from the top of the expression
14 (3x -1)/ 15x^4 + 5x^3
7)
factor 5x^3 from the bottom
14 (3x -1)/ 5x^3 (3x + 1)

Please help me i need help!! How do you solve for M? Explain each step of the solution in a short paragraph
Answer:
M = 4pi²a³ / GT²
Step-by-step explanation:
Cross multiply: T² × GM = GMT²
1 × 4pi²a³ = 4pi²a³
It becomes: GMT² = 4pi²a³
Divide both sides by GT² to solve for M
We have : M = 4pi²a³ / GT²

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?
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.

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?
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

Write an equation for the proportional relationship. Let X represent a length measured in meters and y represent the same length measured in centimeters.
Answer:
[tex]y=100x[/tex]
Step-by-step explanation:
Given that [tex]x[/tex] is the length measured in meters and
[tex]y[/tex] represents the same length measured in centimeters.
Let us first have a look at the relationship between meters and centimeters units of length.
1 unit of length in meters = 100 units of length in centimeters
Therefore, it can be said that:
2 units of length in meters = 200 units of length in centimeters
3 units of length in meters = 300 units of length in centimeters
4 units of length in meters = 400 units of length in centimeters
OR
[tex]x[/tex] units of length in meters = 100[tex]x[/tex] units of length in centimeters
It is given that [tex]y[/tex] is the length in centimeters.
Therefore, the proportional equation can be written as:
[tex]y=100x[/tex]

A rectangle is folded 4 ways. It is folded diagonally at each midpoint of every side.
Answer:
answer is b. a rectangle is folded by a vertical and horizontal line going through its center
Step-by-step explanation:
if you folded it along the lines of symmetry, the rectangle would line up with itself
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.
