Answer:
y = 2x - 9.
Step-by-step explanation:
2y - 4x = -18
Add 4x to both sides:
2y = 4x - 18
Divide both sides by 2:
y = 2x - 9.
Stocks are a good example.
Answer:
A system of linear equations can have no solution, a unique solution or infinitely many solutions. A system has no solution if the equations are inconsistent, they are contradictory. for example 2x+3y=10, 2x+3y=12 has no solution. is the rref form of the matrix for this system.
Step-by-step explanation:
Tell me all ur classes. Like Math, History etc.....Give me all 8 clases name
Amount paid for the first book is $17.
Amount paid for the second book is 0.75 x 8 = $6
Total amount paid = $17 + $6 = $23
Total full cost of the two books = $17 + $8 = $25
Amount of discount = $25 - $23 = $2
% reduction =

Therefore, the <span>percent of the total cost of the two books reduced during the sale</span> is 8%
