3x + 1 = 3x - 8
3x - 3x = -8 -1
0 = -9 (incorrect)
this has NO SOLUTION
Answer: A solution that results in a false statement when substituted back into the original equation.
Step-by-step explanation: An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.
Answer:
the first cell next to 3 (time hours x) is 300
the point is (3, 300)
the second cell is 1000
the point is (10,1000)
the values for the second table should be the same if they have the same unit rate which is 100 watts per hour
Step-by-step explanation:
If there is 100 watts perhour just multiply the number of hours by this unit
The order of these numbers from smallest to largest is:
(-1)2, -1 2/5, -1.4, (1/2)2
-1 2/5 and -1.4 are technically the same, though.
