5n + 34 = -2 ( 1 - 7n)<br>this is due by midnight.<br><br>NO LINKS PLEASE!

kodGreya [7K]

Answer :

n = 4

Step-by-step explanation:

5n + 34 = -2(1-7n)

first distribute

5n + 34 = -2(1) -2(-7n)

5n + 34 = -2+14n

-5n

then get all of n to the same side

36 = 9n

isolate the variable

36/9 = 9n/9

4 = n

Y is inversely proportional to x.

Inessa [10]

Answer:

1. $xy = 63$

2. $y = 3$

Step-by-step explanation:

Given

Variation: inverse Proportion

y = 7, x = 9

Required

- Write an equation connecting y and x

- Find y when x = 21

Given that thee variation is inversely proportional;

This implies that

$y\ \alpha\ \frac{1}{x}$

Convert variation to equation

$y\ = \frac{k}{x}$ ----------- Equation 1

Where k is the constant of variation

Substitute 7 for y and 9 for x in equation 1

$7 = \frac{k}{9}$

Multiply both sides by 9

$9 * 7 = 9 * \frac{k}{9}$

$63 = k$

Substitute 63 for k in equation 1

$y = \frac{63}{x}$

Multiply both sides by x

$x * y = \frac{63}{x} * x$

$xy = 63$

Hence, the equation connecting x and y is $xy = 63$

Solving for when x = 21

Substitute 21 for x in the above equation

$21 * y = 63$

Divide both sides by 21

$\frac{21 * y}{21} = \frac{63}{21}$

$y = 3$

One survey estimates that,on average, the retail value of a mid sized car decreases by8% annually.if the retail value of a car i

Scrat [10]

Percentage by which the average value of mid sized car decreases each year = 8%
Retail value of a car today = v dollars
Amount of decrease in the value of the car after 1 year = (8/100) * v
   = 2v/25 dollars
Then
The equation that represents the value of the car after 1 year = v - (2v/25) dollars
   = (25v - 2v)/25 dollars
   = 23v/25 dollars
So following this expression the value of the mid sized car can be easily determined after 1 year. I hope this is the answer you were looking for and the procedure is also clear to you.
