Is (0,0) a solution to 6x - 7y > 20 please include the steps!

leonid [27]

Answer:

No.

Step-by-step explanation:

To determine if (0,0) is a solution to the inequality, substitute 0 for x and 0 for y and check to see. Thus:

$6x-7y>20$

Substitute 0 for x and 0 for y:

$6(0)-7(0)\stackrel{?}{>}20$

Multiply:

$0-0\stackrel{?}{>}20$

Subtract:

$0\not>20$

So, (0,0) is <em>not</em> a solution.

And we're done!
