Answer:
???????
Step-by-step explanation:
An independent system has different slopes hence has a unique solution.
If two lines have the same slope then, they are inconsistent. The reason is that the two lines could have NO SOLUTION or INFINITELY MANY SOLUTION.
An inconsistent system that have infinitely many solution is said to be dependent.
Now let us make the subject in both equations, to obtain,
For the seccond equation, we have
Wow, the two systems have the same slope and intercept. This means the system has infinitely many solution, hence it is dependent.
<h2>
The two systems are dependent</h2>

Hello!
What am i doing with my life?
Answer:
5 felt pads.
7 cards.
Step-by-step explanation:
Remark
- The total number of items is 12
- So let the felt sheets be x
- Let the cards = y
Equations and Solution
x + y = 12
Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.
0.5x + 0.75y = 7.75 Multiply this equation by 2
x + 1.5y = 15.50 write the first equation underneath and subtract.
<u>x + y = 12</u>
.5y = 3 Divide by 0.5
y = 3/0.5
y = 7
So she can get 7 cards.
x + y = 12
x + 7 = 12
x = 12 - 7
x = 5
So she can buy 5 felt pads.
