5x - 20y = 60...reduce by dividing by 5
x - 4y = 12
this is the same as the other equation....therefore, it is the same line...meaning infinite solutions
=============
y - 7x = -14
y = 7x - 14.....slope = 7, y int = -14

7y - 49x = -2
7y = 49x - 2
y = 7x - 2/7.....slope is 7, y int is -2/7

if the slopes are the same, but the y int are different, then u have a parallel lines with no solutions

denis-greek [22]

Answer:

20 in  

Step-by-step explanation:

Tree 1:

Rate of growth = (½ ft/2 yr)

  12 yr growth = 12 × (½/2)

                       = 6/2

                       = 3 ft

                       = 36 in

Tree 2:

Rate of growth = (4 in/3yr)

  12 yr growth = 12 × (4/3)

                       = 48/3

                       = 16 in

Difference:

Tree 1 - Tree 2 = 36 - 16

                            = 20 in

The trees will differ in height by 20 in.

Any increase in the production of one commodity must be done at the expense of the other, the opportunity cost of the good increased is the number of unit of the other that we have to give up.

in this question the opportunity cost of producing 10 more unit of good X is the 5 units of good Y that was given up.
