When solving a system of two equations via substitution, there will always be only one answer.
sertanlavr [38]
No false.
Remember the solution(s) to a system of equations is where the graphs all intersect if at all.
For the case of say a system of 2 lines, you can see the different possible outcomes..
  -- If the two lines intersect at some point (x,y), that is one unique solution
  -- If the two lines are parallel to each other, you see there are no intersection points and therefore this system of two parallel lines has no solutuion.
  -- If the two lines overlap, really the same line written as a multiple of the other line, then you see they intersect at all points along the line, here there are infinite solutions.

A greeting card company can produce a box of cards for $7.50. If the initial investment by the company was $50,000, how many box
larisa86 [58]

Answer:

If cost of one box of card is $7.50 then the no of cards produced is 6667 cards and if cost of one box of card is $10.50 then the no of cards produced is 4762 cards

Step-by-step explanation:

The cost of one box of cards = $7.50

Initial investment = $50,000

No of box of cards produced = Initial investment / cost of one box of card

No of box of cards produced = 50,000/7.50

No of box of cards produced = 6667 cards.

if the cost of one box of cards is increased = $10.50

No of box of cards produced = Initial investment / cost of one box of card

No of box of cards produced = 50,000/10.50

No of box of cards produced = 4762 cards.

So, if cost of one box of card is $7.50 then the no of cards produced is 6667 cards and if cost of one box of card is $10.50 then the no of cards produced is 4762 cards

Help please!!<br> Solve for X.
Mekhanik [1.2K]

9514 1404 393

Answer:

  3) x = 9

  4) x = 3

Step-by-step explanation:

3) The two short segments are indicated as having a sum equal to the long segment.

  (x +2) +(-5 +x) = 15

  2x = 18 . . . . . . . . . . . . add 3

  x = 9 . . . . . . . . . divide by 2

(This makes the segments be 9+2 = 11 and -5+9 = 4, which total 15.)

__

4) Same deal.

  3x +3 = 4x

  3 = x . . . . . . . . subtract 3x

(This makes the segments be 3(3) = 9 and 4(3) = 12, where 9+3=12.)
