Mathematics

IRISSAK [1]1 year ago
5 0

Answer:

x = 3

y = 2

Step-by-step explanation:

Equations

7x - 7y = 7                            

-4x - 7y = - 26                          Multiply both sides of the equation by - 1

-1(-4x - 7y = - 26)

4x + 7y = 26

Solution

Add the two equations together

7x - 7y = 7      

4x + 7y = 26

11x = 33                                  Divide by 11

11x/11 = 33/11

x = 3

4x + 7y= 26                           Use this equation to solve for y. Use x = 3

4*3 + 7y = 26                        Combine the left

12 + 7y = 26                          Subtract 12 from both sides

12 - 12 + 7y = 26 - 12            Combine

7y = 14                                  Divide by 7

7y/7 = 14/7

y = 2

Matt is mailing a rectangular package at the post office the box's volume is 24 in.³ what are all of the possible dimensions len
Greeley [361]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Volume = 24 in³

Process

1.- Find the prime factors of 24

                        24  2

                         12  2

                          6  2

                          3  3

                           1

2.- Volume of a rectangular package

             Volume = length x height x width

3.- Possible values are, combine the prime factors to find the volume

             Volume = 4 x 2 x 3   or

             Volume = 2 x 4 x 3

             Volume = 3 x 2 x 4

             Volume = 2 x 2 x 6

             Volume = 6 x 2 x 2

             Volume = 2 x 6 x 2

             Volume = 12 x 2 x 1

             Volume = 1 x 12 x 2

             Volume = 2 x 1 x 12

Answer:

Between 1000 and 5000 snowboards will make the function AP(x) >0.

Step-by-step explanation:

Since x can only take possitive values, we have that AP(x) = P(x)/x > 0 if and only if P(x) > 0.

In order to find when P(x) > 0, we find the values from where it is 0 and then we use the Bolzano Theorem.

P(x) = R(x) - C(x) = -x²+10x - (4x+5) = -x²+6x - 5. the roots of P can be found using the quadratic formula:

r_1,r_2 = \frac{-6 ^+_- \sqrt{6^2-4*(-1)*(-5)} }{2*(-1)} = \frac{-6^+_-\sqrt{16}}{-2} = \{1, 5\}

Therefore, P(1) = P(5) = 0. Lets find intermediate values to apply Bolzano Theorem:

  • P(0) = -5 < 0 ( P is negative in (-∞ , 1) )
  • P(2) = -4+6*2-5 = 3 > 0 (P is positive in (1,5) )
  • P(6) = -36+36-5 = -5 < 0 (P is negative in (5, +∞) )

The production levels that make AP(x) >0 are between 1000 and 5000 snowboards (because we take x by thousands)
