Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
• 1 + cot²x = csc²x
Consider the left side
x - 
x
Factorise as a difference of squares
= (csc²x - cot²x)(csc²x + cot²x)
= (1 + cot²x - cot²x)(csc²x + cot²x)
= csc²x + cot²x
= csc²x + csc²x - 1
= 2csc²x - 1 = right side ⇒ verified
13xy^2-10xy-23=0
you first add the like terms and rewrite and thats how you get the answer
15flowers/3seedpackets
5 flowers/seed packet
*4
————————————
20 follows equals 4 seed packets
your answer is ——-^^^^^^^^^^^^^^^
We want to solve
Subtract 5 from each side.
Divide each side by 3.
Take natural logs of each side.
Divide each side by 2.
x = 0.9962
Answer: x = 0.996 (nearest thousanth)
-2,-6 is the answer to the linear combination method
