Answer:
Step-by-step explanation:
<em>Replace it with y</em>
<em>Exchange the values of x and y</em>
<em>Solve for y</em>
<em>Subtracting 1 from both sides</em>
<em>Dividing both sides by 2</em>
<em>Replace it by </em>
So,
Simplify:
37 - (-3)^2 + 30/(-3)x^2
= 37 + - 9 + - 10x^2
Combine like terms:
= 37 + - 9 + - 10x^2
= ( - 10x^2) + (37 + - 90
= - 10X^2 + 28
Answer: - 10x^2 + 28
To Factor:
37 - (- 3)^2 + 30/- 3x^2
- 10x^2 + 28
- 2(5x^2 - 14)
Answer: - 2(5x^2 - 14)
I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -
Hope that helps!!!!
The quotient is x^3 + 4x^2 -x + 1.
Solution:
By polynomial grid division, we start by the divisor 3x + 10 placed on the column headings.
3x 10
x^3 3x^4
We know that 3x^4 must be in the top left which means that the first row entry must be x^3. So the row and column multiply to 3x^4. We use this to fill in all of the first row, multiplying x^3 by the terms of the column entries.
3x 10
x^3 3x^4 10x^3
4x^2
We now got 10x^3 though we want 22x^3. The next cubic entry must then be 12x^3 so that the overall sum is 22x^3.
3x 10
x^3 3x^4 10x^3
4x^2 12x^3
Now we have 40x^2, so the next quadratic entry must be -3x^2 so that the overall sum is 37x^2.
3x 10
x^3 3x^4 10x^3
4x^2 12x^3 40x^2
-x -3x^2 -10x
This time we have -10x, so the next linear entry must be 3x so that the overall sum is 7x.
3x 10
x^3 3x^4 10x^3
4x^2 12x^3 40x^2
-x -3x^2 -10x
1 3x 10
The bottom and final term is 10, which is our desired answer. Therefore, we can now read the quotient off the first column:
3x^4+22x^3+37x^2-7x+10 / 3x + 10 = x^3 + 4x^2 -x + 1
Answer:
x = 17
Step-by-step explanation:
For the lines to be parallel, then
(8x - 31) and (6x + 3) are alternate angles and congruent, then
8x - 31 = 6x + 3 ( subtract 6x from both sides )
2x - 31 = 3 ( add 31 to both sides )
2x = 34 ( divide both sides by 2 )
x = 17
Answer: not sure what the question it is that you asking but yeah, it increased by a 1.19…
