Answer:
The binomial theorem allows you to write out the expansion of your polynomial immediately. (I feel like this is good enough)
Step-by-step explanation:
<em>It also allows you to answer such questions as:</em> "What is the coefficient of x20 in (1+x)100?" Its generalization to non-integer exponents allows you to get the expansion of (1−x)−1/2. There are all sorts of reasons.
Answer:
wait thank you!!
explanation:Ahhh I love free points lol
Y=-X
This is because as the value of x goes up, the value of y goes down
Answer:
x=7/5
Step-by-step explanation:
First you need to get X by itself. You simplify the right side, getting -5, and then subtract 9 from both sides, getting -10x on one side and -14 on the other. Divide both sides by -1, getting 10x=14, divide both sides by 10 which leaves x=14/10. This can be simplified to be 7/5
