Which set of ordered pairs does not represent a function? {(-5, -2), (3,-2), (5, -9), (6, -7)}
{(-1, -3), (-4,9), (-7,2), (3,9)}
{(4,5), (-8,-6), (-7, -1), (6,-1)}
{(-4,-9), (-4,4), (-2,2), (9,5)}

idk

step-by-step explanation:

stethere all not eveanp-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
