Answer:
3,528.57142857
Step-by-step explanation:
For a system of linear equations to have no solution, they must be parallel. If you imagine the graph of two parallel lines, they can never intersect, meaning there cannot be a solution/a point that is on both lines.
For two lines to be parallel they must have the same slope, so the m value of both equations are the same. The b value can be any value you want, as long as they don't have the same b value (or else they'd be the same line! and the same lines have an infinite number of solutions).
One pair could be:
y=3x+3 and y=3x+9
But you can come up one yourself you'd like :)
Answer: there were 19 five dollar bills and 17 20 dollar bills.
Step-by-step explanation:
Let x represent the number of five dollar bills that were received.
Let y represent the number of twenty dollar bills that were received.
Parts of the proceeds from a garage sale was $435 worth of five dollars and $20 bills. This means that
5x + 20y = 435 - - - - - - - - - - -1
If there were two more five dollar bills than $20 bills, it means that
x = y + 2
Substituting x = y + 2 into equation 1, it becomes
5(y + 2) + 20y = 435
5y + 10 + 20y = 435
25y = 435 - 10 = 425
y = 425/25 = 17
x = y + 2 = 17 + 2
x = 19
