. Which of the following ordered pair could NOT be included in this set if it is a function?
{ (-4, 2), (3, 6), (4, 3), (x, y) }
(x, y) = (-3, 6)
(x, y) = (1, 2)
(x, y) = (4, -3)
(x, y) = (3, 6)

Step-by-step explanation:

It cannot be (4, -3) as there would be 2 outputs (3 and -3) for the input 4, therefore it becomes a one-to-many relationship and not a function.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
