Step-by-step explanation:

step 1. slope = rise/run

step 2. the rise is the height between any 2 points

step 3. the run is the distance left or right between the same 2 points

step 4. if the line goes up "left to right" the slope is positive, down it is negative

step 5. slope = + 6/2 = 3.

Compute $121_3+2122_3-1200_3-2111_3$. Express your answer in base 3.

vfiekz [6]

Answer:

-221 base 3

Step-by-step explanation:

We are to calculate the value of the numbers in base 3. One of the ways to do that is to first convert each number to base 10. Do the arithmetic, then convert back to base 3.

121 base 3 +2122 base 3 - 1200 base 3 - 2111 base 3

Let's convert to base10

See attachment for details

From the workings,

121 base 3 + 2122 base 3 - 1200 base 3 - 2111 base 3 = -221 base 3
