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:
6.
Just count the x's on the graph...
Okay so this is how I would figure this out:
John + John's Wife
1 son + 1 son } 2 sons
2 sons + 2 sisters } sons have 2 sisters
there are 6 people total in their family:
1. John
2. John's wife
3. 1 son
4. 2 son
5. 1 daughter
6. 2 daughter
There are 6 members total.
Hope this helped! :)
Answer:
<h3>The answer is - 1/3</h3>
Step-by-step explanation:
To find the common ratio of the sequence divide the next term by the previous term
That's
- 2 / 6 = - 1/3
2/3 ÷ -2 = 2/3 × -1/2 = - 1/3
Hence
The common ratio is - 1/3
Hope this helps you
Multiply the first coefficient (3) and the last term (2) to get 3*2 = 6
We need to find two numbers that
a) multiply to 6
AND
b) add to -5 (middle coefficient)
Such two numbers are -3 and -2
-3 times -2 = 6
-3 plus -2 = -5
So we can break up the -5x into -3x-2x and then factor by grouping
--------------
3x^2-5x+2
3x^2-3x-2x+2
(3x^2-3x)+(-2x+2)
3x(x-1)+(-2x+2)
3x(x-1)-2(x-1)
(3x-2)(x-1)
So the two factors are (3x-2) and (x-1)
The answers are A and C
