1) 2x=6
x=3
2)x=3
3) 4x=12
x=3
-3 is the y intercept, remember y=mx+b.
b is always the y intercept.
rewritten this equation would look -18=4x-3
Answer:
supplementry angles
Step-by-step explanation:
they add up to 180 degrees
Set it up like this: 2<em>n</em>+3 <<em> n</em>-4
Solve for <em>n</em>:
2<em>n</em>+3 < <em>n</em>-4
-<em>n</em> -<em>n</em> (1st step: get <em>n</em> on one side by itself)
<em>n</em>+3 < -4
-3 -3 (2nd step: subtract 3 from both sides)
<em>n</em> < -7
The answer is n < -7
Add all of them together and then divide by the number digits. So it would be 6/4= 3/2
