Answer:
1. [tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 1}}}}}[/tex]
2. [tex] \boxed{ \bold{ \huge{ \boxed{ \sf{n = - 5}}}}}[/tex]
Step-by-step explanation:
1. [tex] \sf{ \frac{6}{x + 1} = \frac{3}{x} }[/tex]
Do cross multiplication
[tex] \dashrightarrow{ \sf{6x = 3(x + 1)}}[/tex]
Distribute 3 through the parentheses
[tex] \dashrightarrow{ \sf{6x = 3x + 3}}[/tex]
Move 3x to left hand side and change it's sign
[tex] \dashrightarrow{ \sf{6x - 3x = 3}}[/tex]
Collect like terms
[tex] \dashrightarrow{ \sf{3x = 3}}[/tex]
Divide both sides by 3
[tex] \dashrightarrow{ \sf{ \frac{3x}{3} = \frac{3}{3} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{x = 1}}[/tex]
The value of x is 1

2. [tex] \sf{ \frac{2}{6} = \frac{2n + 8}{n - 1}} [/tex]
Do cross multiplication
[tex] \dashrightarrow{ \sf{2(n - 1) = 6(2n + 8)}}[/tex]
Distribute 2 through the parentheses
Similarly, distribute 6 through the parentheses
[tex] \dashrightarrow{ \sf{2n - 2 = 12n + 48}}[/tex]
Move 12n to left hand side and change it's sign
Similarly, move 48 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{2n - 12n = 48 + 2}}[/tex]
Collect like terms
[tex] \dashrightarrow{ \sf{ - 10n = 48 + 2}}[/tex]
Add the numbers : 48 and 2
[tex] \dashrightarrow{ \sf{ - 10n = 50}}[/tex]
Divide both sides by -10
[tex] \dashrightarrow{ \sf{ \frac{ - 10n}{ - 10} = \frac{50}{ - 10} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{n = - 5}}[/tex]
The value of n is -5 .

Two numbers have a sum of 2 and a difference
of -16. What are the numbers?
Answers
Answer:
-7 & 9
Step-by-step explanation:
(-7) + 9 = 2
(-7) - 9 = -16
x + y = 2
x - y = -16
Add the equations together to eliminate one of the variables.
2x = -14
Divide both sides by 2
x = -7
Let's plug -7 into x for our first equation.
-7 + y = 2
Add 7 to both sides.
y = 9
Write an equation that represents the line.
Use exact numbers.
Answers
Answer:
y=(7/5)x + 34/5
Step-by-step explanation:
All straight lines generally follow the equation format of: y=mx+c
Where m is the slope/gradient of the line, and c is a constant, the y-intercept, the y value when x=0.
To start, we need to find the slope, which we do by dividing the rise of the line by the run, that is the difference between the y value of two points divided by the different between the x value of two points.
We can use the two given points on the graph: (-7,-3) and (-2,4).
The rise is 7 because 4-(-3)=7, and the run is 5 because -2-(-7)=5.
Therefore the slope is 7/5.
so our equation so far is:
y=(7/5)x + c, (It is positive because the line is 'going upwards'.)
Now to find the c, we can just substitute in a pair of coordinates, we can use (-2,4):
4= (7/5)(-2) + c
4 = -14/5 + c
4 + 14/5 = c
c= 34/5
Therefore our full equation is:
y=(7/5)x + 34/5

Answer:
y = - [tex]\frac{63}{4}[/tex] or - 15.75
Step-by-step explanation:
Order of operations.
y + [tex]\frac{9}{2}[/tex] = y - [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex] Subtract y from each side.
y - y + [tex]\frac{9}{2}[/tex] = y - y - [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex]
[tex]\frac{9}{2}[/tex] = - [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex] Add [tex]\frac{3}{4}[/tex] to each side
[tex]\frac{9}{2}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{3}{4}[/tex] + [tex]\frac{3}{4}[/tex] - [tex]\frac{y}{3}[/tex]
[tex]\frac{9}{2}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{y}{3}[/tex] Find the common denominator for [tex]\frac{9}{2}[/tex] and [tex]\frac{3}{4}[/tex], which is 4
[tex]\frac{9}{2}[/tex] * [tex]\frac{2}{2}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{y}{3}[/tex]
[tex]\frac{18}{4}[/tex] + [tex]\frac{3}{4}[/tex] = - [tex]\frac{y}{3}[/tex]
[tex]\frac{21}{4}[/tex] = - [tex]\frac{y}{3}[/tex] Multiply each side by 3
[tex]\frac{21}{4}[/tex] * 3 = - [tex]\frac{y}{3}[/tex] * 3
[tex]\frac{63}{4}[/tex] = - y Divide each side by -1
y = - [tex]\frac{63}{4}[/tex] = - 15 [tex]\frac{3}{4}[/tex]
y = - 15.75
Step-by-step explanation:
There are 2 scenarios below. One without parenthesis and the second with. I believe the second one is your question.
y+9÷2=y-3÷4-(y/3)y - y + y/3 = - 3/4 - 9/2 ⇒ combining like termsy/3 = -3/4 - 18/4y/3 = -21/4y = -21/4*3y = -63/4y = - 15 3/4===============
(y+9)÷2=(y-3)÷4-(y/3)12*(y+9)/2 = 12* (y-3)/4 - 12*y/3 ⇒ this is to get rid of fraction6(y+9) = 3(y-3) - 4y6y + 54 = 3y - 9 - 4y6y + 54 = - y - 96y + y = - 9 - 547y = - 637y/7 = -63/7y = -9(WILL MARK BRAINLIEST PLEASE HELP!)

9x [tex]10^7[/tex] is 30,000 times larger than 3 x 10³.
What is Exponents?The number of times a number has been multiplied by itself is referred to as an exponent.
The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.
Given:
9x [tex]10^7[/tex]
The number [tex]10^7[/tex] can be expanded as
[tex]10^7\\[/tex] = 10,000,000
and, 9x [tex]10^7[/tex] = 9 x 10,000,000
= 90,000,000
The number [tex]10^3[/tex] can be expanded as
[tex]10^3[/tex] = 1000
and, 3 x 10³ = 3 x 1000
= 3000
Then, 90,000,000/3,000
=30,000
Hence, 9x [tex]10^7[/tex] is 30,000 times larger than 3 x 10³.

f(k-1) = 5k² - 4k - 4
The given function is:
f(x) = 5x² + 4x - 5
To find f(k-1), substitute x = k-1 into f(x)
f(k-1) = 5(k-1)² + 4(k-1) - 5
f(k-1) = 5(k² - 2k + 1) + 4k - 4 - 5
f(k -1) = 5k² - 10k + 5 + 4k -9²

Answers
Answer:
A. {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)}
Step-by-step explanation:
I just did the quiz but basically you can switch the coordinates around to view the coordinates of the inverse function. If there are x values that are the same number, it does not pass the line test making it not a function with an inverse function.
The function has an inverse that is also a function will be {(–4, 3), (–2, 7), (–1, 0), (4, –3), (11, –7)} so correct option will be (A).
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
The machine may only produce one output for each input and will only accept inputs that are specifically listed as part of the function's domain.
In other words, the function is a relationship between variables and the nature of the relationship.
In the given question
We know that a function is only a function such that there is a unique value of y corresponding to x.
An inverse function will only be a function if the function which is going to be inverse is a function.
In option (A) all value of x corresponding to y are different but in all remaining options the values are repeating hence that will be not a function since only (A) has to inverse

Answers
Answer:
136 + 129= 265
Step-by-step explanation:
when you're finding the difference and one number is positive and the other is a negative number you will add the negative instead of add them together so you would 129 to 136 which would equal 265. this rule applies to the opposite too. if both numbers are positive, then you would subtract them.
