<u>Answer:</u>
37th term of given arithmetic sequence 
= 2.3; d = -2.3 is -80.5.
<u>Solution:</u>
Given that
Need to determine 37th term, when = 2.3, d = -2.3
Means first term of arithmetic sequence = = 2.3 and common difference d = -2.3
<u><em>Formula for nth term of arithmetic sequence is </em></u>
--- equation 1
We need to determine 37th term so n = 37.
On substituting given values in equation (1) we get
Hence 37th term of given arithmetic sequence is -80.5
Answer: y = (1/2)x + 2
Explanation
310y=2y^2+xy. This is the answer
Infinitely many is the first one, because you can convert one equation into another one (3x-3y=-18---> x-y=-6, ---->y=x+6)
second one is one solution, because
y=-4x+11 and y=11+6x,--->-4x+11=11+6x, -4x-6x=0, x=0
third one
y =-2x+5 and y=-7-2x ,-2x+5=-7-2x, --->5=-7 false , no solutions
Sqrt89 is between sqrt 81 and sqrt100.
Sqrt 81 = 9, sqrt 100 = 10
So. sqrt89 is between 9&10.
