Answer:
6x - 11y = -13 is the answer.
Step-by-step explanation:
Let's plug in the points to see what sticks.
Start with (-4, -1)
1) 11x - 6y = 11(-4) - 6(-1) = -44 + 6 = -38 
13
2) 6x - 11y = 6(-4) - 11(-1) = -24 + 11 = -13
3) 6x - 7y = 6(-4) - 7(-1) = -24 + 7 = -17 17
4) 6x - 11y = 6(-4) - 11(-1) = -24 + 11 = -13 13
The only one that fits is #2. Let's try the other point to be sure.
2) 6x - 11y = 6(1.5) - 11(2) = 9 - 22 = -13
Answer:
The 4 in the hundreds place has a value 10 times as great as the 4 in the tens place.
Step-by-step explanation:
440 = 400 + 40 + 0
the hundreds place is worth 400 here
it is worth 10x the tens place (40 here)
72 ÷ o should be the algebraic expression.
Answer:
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
Answer:
This is a 25% decrease
Step-by-step explanation:
percent change = (old - new)/old * 100 %
The new price is 15
The old price is 20
Since the new price is less than the old price, it is a decrease
percent change = (20-15)/20 * 100 %
= 5/20 * 100%
=.25 * 100%
= 25%
This is a 25% decrease
