which expression has a coefficient of positive 1 for the the term n ?
a. 5n^2+6n-1
b. 2n^2-5n+1
c. 3n^2+n-2
d. 4n^2-n+9

Option C

Step-by-step explanation:

Verify each expression

case A) we have

In this expression the term of n is 6n

so

has a coefficient of positive 6

case B) we have

In this expression the term of n is -5n

so

has a coefficient of negative 5

case C) we have

In this expression the term of n is n

so

has a coefficient of positive 1

case D) we have

In this expression the term of n is -n

so

has a coefficient of negative 1

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
