Andrew bought 3 baseball cards for $240. After a few months, he got an offer from his friend Jack to buy the first card for doub

le its original value, along with either the second or third card. Andrew decided to sell the first card (at double its original value) along with the second card (at its original price) and got $320 for it. Or, selling the first card (at double its original value) card along with the third card (at its original price) would have only got him $280. What were the original prices for each of the 3 baseball cards? (80, 120, 40) (80, 130, 30) (130, 90, 20) (120, 80, 40) NextReset

I don't know how to do this​
Gre4nikov [31]

Answer:

x = -11/5 and y = 24/5

Step-by-step explanation:

Use elimination.

First, we need to multiply so that at least one variable can cancel out.

We can multiply the top equation by 2.

So we get

4x + 6y = 20

Then, we can use elimination.

The x's cancel out.

So we get 5y = 24

Or y = 24/5

Then, we can plug in this y value back into the first equation to find x.

2x + 3(24/5) = 10

2x + 72/5 = 50/5

2x = -22/5

x = -11/5

So x = -11/5 and y = 24/5

PLEASE ANSWER THIS

B) If the line is parallel, that means the slope is the same.
    The slope for the original line is \frac{-1-0}{6-2} = \frac{-1}{4}.
    The second form of coral line would be y = -1/4x + (any number). You could          use y = -1/4x + 3.

c) Solve 12x = 24 + 3y for y.
    3y = 12x - 24
    y = 4x - 8
    Perpendicular lines have negative reciprocal slopes... the negative reciprocal      for -1/4 is 4. So yes, the third coral structure is perpendicular to the first coral.
