Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
[tex]\frac{4}{x}=\frac{3x+2}{x^2}[/tex]
Step 2: Solve for x
Cross multiply: [tex]4x^2=x(3x+2)[/tex]Distribute x: [tex]4x^2=3x^2+2x[/tex]Subtract 3x² on both sides: [tex]x^2=2x[/tex]Subtract 2x on both sides: [tex]x^2-2x=0[/tex]Factor: [tex]x(x-2)=0[/tex]Solve: [tex]x = 0, 2[/tex]Step 3: Check
Plug in x to verify it's a solution.
Substitute: [tex]\frac{4}{0}=\frac{3(0)+2}{0^2}[/tex]Evaluate: undef (cannot divide by 0)Substitute: [tex]\frac{4}{2}=\frac{3(2)+2}{2^2}[/tex]Evaluate: [tex]2=\frac{6+2}{4}[/tex]Evaluate: [tex]2=\frac{8}{4}[/tex]Evaluate: [tex]2=2[/tex]Solve. Check your answer.

12 = 10
18 = x
Answers
Step-by-step explanation:
12=10 I think you have to add 10+2and then you get 12.
18=×you will have to multiply 18 by a number probably by 10 or 12
this is because 12:10 which is also 6:5.
then you multiply 6 by 3 and get 18. so then you multiply 5 by 3 and get 15

Answer:
f^-1(x) = 4(x+5)/3
Step-by-step explanation:
Let f(x) = y
So, y = (3/4)x - 5
y + 5 = (3/4)x
4(y+5)/3 = x
The steps are first to make a variable that holds the same value as the function, then from there you simplify and eventually make x the subject of the equation.
There is a proportional relationship between the area of a wall and the amount of paint needed to cover it.
A. What is the constant of proportionality for that relationship? Explain.
Answers
Answer:
Constant of proportionality [tex] = \frac{1}{400} [/tex]
Step-by-step explanation:
A. The constant of proportionality can be calculated as the ratio of y to x. In this case, y = amount of paint, while x = the area of the wall
The area of the wall determines the amount of paint needed to cover the wall.
Constant of proportionality, k = y/x.
Any given pair cam be used as y and x to find k.
Thus, using (100, ¼),
[tex] k = \frac{\frac{1}{4}}{100} = \frac{1}{4}*\frac{1}{100} [/tex]
Constant of proportionality [tex] = \frac{1}{400} [/tex]
This means that as area of the wall increases, amount of paint increases and the ratio between them would always be [tex] \frac{1}{400} [/tex].
1999 total revenue of a company from music sales and Licensing was 14.2 billion dollars. It was forecasted that this number would continue to drop until it reaches 5.3 million in 2014. Find the percent decrease in music revenue.
Answers
Answer:
62.67%
Step-by-step explanation:
Total revenue of a company from music sales is 14.2 billion dollars in 1999.
It reaches 5.3 million in 2014.
We need to find the percent decrease in music revenue. It can be given by :
[tex]\%=\dfrac{|\text{original value-decrement value}|}{\text{original value}}\times 100\\\\\%=\dfrac{|14.2-5.3|}{14.2}\times 100\\\\\%=62.67[/tex]
So, the percent decrease in music revenue is 62.67%.

Step-by-step explanation:
The X value repeats itself
Step-by-step explanation: In order for a function not to be a relation,
each x-coordinate must correspond to more than one y-coordinate.
Notice that in third relation, the 1 pairs with a 3
in one case and it pairs with a 7 in the other case.
Since each x-coordinate pairs with more than one y-coordinate,
this relation is not a function but the other ones are functions.

The dimensions of a rectangular garden are: Length (2x + 3) and the width is (3x-5) Find the value of x if the perimeter is equal to 26.
Answers
length=(2x-3)
width=(3x-5)
perimeter=26
perimeter= (2 times length) + (2 times width)
26= 2(2x-2) + 2(3x-5)
26 = 4x - 6 + 6x - 10
26 = 10x -16
26 + 16 = 10x -16 + 16
10 = 10x
10 ÷ 10 = 10x ÷ 10
