Answer:
So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
Step-by-step explanation:
Given:
..............Equation ( 1 )
................Equation ( 2 )
To Find:
Whether Equation ( 1 ) is Equivalent to Equation ( 2 )
Support your answer by evaluating the expression for t = 2.
Solution:
For t=2 Equation ( 1 ) we get
For t=2 Equation ( 2 ) we get
From above we get two different values
So Equation ( 1 ) is NOT Equivalent to Equation ( 2 )
Answer: 1
Step-by-step explanation:
First you need to multiply 3 x 3 (9), because that's all 3 squared means.
Now the equation should be 9x-6x+3=0
Next we need to combine like terms. Do 9x - 6x which should give you 3x
Now your equations should be 3x+3=0
Now for the somewhat harder part...
Under the three (the one without the x) write -3 and under the zero write the same thing. the +3-3 cancels out so just put a line or something across it.
0-3= -3
so now you should have...
3x=-3 ignore the 3x, at this point it's useless in getting the answer because it would cancel out.
-3 divided by -3 is 1 because a negative (-) divided by a negative (-) equals a positive (+).
The answer should be x = 1
