Answer: No
The order of variables does not matter when combining like terms in algebra, because of the commutative property.
Explanation:
Consider the addition of two algebraic expressions.
f(x) = x³ - 5x² + 3x - 2
g(x) = 6x³ + 10x² - 7x + 9
Add f(x) and g(x).
f(x) + g(x) = x³ - 5x² + 3x - 2 + (6x³ + 10x² - 7x + 9)
= x³ + 6x³ - 5x² + 10x² + 3x - 7x - 2 + 9
= 7x³ + 5x² - 4x + 7
Now add g(x) and f(x) in order to change the order of variable addition.
g(x) + f(x) = 6x³ + 10x² - 7x + 9 + (x³ - 5x² + 3x - 2)
= 6x³ + x³ + 10x² - 5x² - 7x + 3x + 9 - 2
= 7x³ + 5x² - 4x + 7
The two additions yield the same result, although the order of variable was reversed during the addition.
In general, algebraic operations are commutative.
Answer:
Air transportation.
Explanation:
Responsive transportation is a form of shared transportation system where regular public transit or a personalized taxi that are frequent on a particular route are used to enhance a speedy and economical delivery of items and passengers en - route different destinations but in the same direction.
Looking at the three major modes of transportation which are road , air and sea, the one that suits this scenario is the Air system.
Being an international route , the road system does not fit in , and the ship on the sea is not a good option for responsive transportation considering its speed.
He should remind Dave about the racing bike purchase contract if he really wants the bike. The action can be done if there was a binding clause in the contract which binds Sam as the only buyer. Sam has a better option which is to sell the contract to Gene with a price higher than the first price but lower than the last price in order to gain a return from the bike purchase contract.
Answer:
"Why We've Been Hugely Underestimating the Overfishing of the Oceans"
Determining whether each statement is true or false:
a. False
b. True
c. False
d. True
Explanation:
The article "Why We've Been Hugely Underestimating the Overfishing of the Oceans," was published by the Washington Post on January 19, 2016. It was written by Chelsea Harvey. It tried to show how the world fish stock had been declining due to overfishing. This is why it provided a report contrary to the FAO report.
While the FAO report noted that the peak of worldwide catches was at 86 million tons in 1996, the contrary and independent report, using "catch reconstruction" showed that the peak was at 130 million tons in 1996. The reconstructed research also showed that worldwide fish catches had suffered declines ever since the 1996 peak, thereby threatening "world food security and marine ecosystems". The contrary report also suggested that all stakeholders must collaborate so that fish stocks can rebuild naturally.
