zlopas [31]

Answer:

x = -(3 y)/2

Step-by-step explanation:

Solve for x:

-2 x - 3 y + 3/(x + y) - (3 x - 3 y)/(x^2 - y^2) = 0

Simplify and substitute z = x + y.

-2 x - 3 y + 3/(x + y) - (3 x - 3 y)/(x^2 - y^2) = -y - 2 (x + y)

= -y - 2 z:

-y - 2 z = 0

Multiply both sides by -1:

y + 2 z = 0

Subtract y from both sides:

2 z = -y

Divide both sides by 2:

z = -y/2

Substitute back for z = x + y:

x + y = -y/2

Subtract y from both sides:

Answer:  x = -(3 y)/2

vodomira [7]

Answer:

C = pi * d

Step-by-step explanation:

C = 2 * pi *r

We can replace 2 * r with d since the diameter is twice the radius

C = pi * 2*r

C = pi * d

A firm buys on terms of 3/15, net 45. It does not take the discount, and it generally pays after 85 days. What is the nominal an
Tresset [83]

Answer:

  a. 16.13%

Step-by-step explanation:

By not taking the discount, the company pays ...

  1/(1 -0.03) -1 ≈ 3.0928%

for the use of the creditor's money for 85 -15 = 70 days.

This translates to an annual rate x according to the proportion ...

  3.0928%/70 = x/365

  x = (365/70)(3.0928%) ≈ 16.13%

The APR of the credit the company is using is about 16.13%.

What is the smallest 4-digit positive number divisible by 2, 3, 4, 5, 6, 8, 9, and 10?
Kruka [31]
<h3>Answer: 1080</h3>

===================================================

Explanation:

let's find the prime factorization for each value. If the value is prime, then just move onto the next value

2 = 2 ... already prime, nothing needed to do here

3 = 3

4 = 2*2

5 = 5

6 = 2*3

8 = 2*2*2

9 = 3*3

10 = 2*5

The list of prime factors that show up are: {2, 3, 5}

We have '2' show up at most 3 times, the prime '3' show up at most 2 times, and the prime '5' show up at most 1 time.

This means 2^3*3^2*5 = 360 is the LCM of the list {2,3,4,5,6,8,9,10}

Any multiple of 360 will also be a common multiple of the original list of values.

Multiples of 360: {360, 720, 1080, ...}

We see that 1080 is the smallest 4-digit multiple of 360.
