Answer: y=1/2x-2
Step-by-step explanation:
y=mx+b
2y-x=-6
2y=x-6
y=1/2x-3
y-y1=m(x-x1)
y+4=1/2(x+4)
y+4=1/2x+2
y=1/2x-2
Answer:
The answer is option B
Step-by-step explanation:
To find the coefficient of the third term in
Rewrite the expansion in the form
where n is the index
So we have
After that we use the formula
where r is the term we are looking for
For the third term we are looking for the term containing x²
that's
r + 1 = 3
r = 2
So to find the coefficient of the third term
We have
