Answer:

Last one:

<h3><u>y = 8 - x</u></h3>

Step-by-step explanation:

y = 8 - x

<h3>Replace x and y in this function </h3>

12 = 8 - 4

12 = 4 (impossible)

<h3>So, (4 , 12) is not solution for: y = 8 - x</h3>

if an ordered pair is a solution, it should satisfy the equation.

see the first option

y=3x , if you put $x=4$ and $y=12$

you'll get $12=12$ which is true.

now the last option, $y=8-x$ put $x=4$ and $y=12$

$12=8-4\implies 12\ne4$ thus it is not a solution.

So option 4 is correct

Korolek [52]

Answer:

B

Step-by-step explanation:

10(10m+6)<=12        

100m+60<=12       Distributive Property

100m     <=12-60

100m    <=-48

     m    <=-48/100

     m    <=-.48

This says values for m that are less than or equal to -.48

-.48 is between -1 and 0 so the answer is B
