Which set of ordered pairs does not represent a function? {(-6, -9),(-2, -3),(-9, 2), (2, -3)}
O{(-2,0), (-5,8), (7,9), (6,8)}
{(6,9), (-7,8), (1,-4), (8,8)}
{(-2,-6),(-1,2),(-2,- 7),(6,6)}

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

192/15 = 12.8.

12.8

step-by-step explanation:

192/15 is 12.8.

however, it says to round to the nearest foot, which would equal 13.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
