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

A metal washer has an outer diameter of 14mm and an inner diameter of 6mm.Use the value of 3.14 for the to find the area of the
Elena L [17]

Answer:

502.4 mm^2

Step-by-step explanation:

First find the area of the larger circle, and then that of the smaller one.

Then subtract the latter (2nd) area from the first.

larger circle area           smaller circle area

-------------------------           ---------------------------

 3.14(14 mm)^2                   3.14(6 mm)^ 2

This comes out to 3.14[14^2 - 6^2] mm^ 2 =  3.14[196 - 36] mm^2, or

3.14(160 mm^2) = 502.4 mm^2

The area of the metal washer is 502.4 mm^2.
