Since a polynomial is where we have like terms such as (1 x 10²) and (4 x 10²), we can add these up using the distributive property to get (5 x 10²) but still keep the 10². For example, it's similar to if we had 2x²+3x²=5x². The x² is still there, but we add up the 2 and 3. Similarly, we can add these up for 10^1 and 10^0
The answers are 4:00am, and 28 chores.
The constant speed, or "average rate of change" is their slope.
so hmmm looking at Fred's graph, let's pick two points on the line, say 0,0 the origin and 8,2
now, for Sam, let's use the last two points in the table then,
-2y-9=2y+7
No solution because -9 doesn’t equal 7
