Answer:
I answered ur question in ur previous post
Good Luck!
Distribute 1/4 through the parenthesis:
1/4x + 3/2 + 1/8(x-3)= 1/3(x+4)
Distribute 1/8 through the parenthesis:
1/4x + 3/2 + 1/8x - 3/8= 1/3(x+4)
Distribute 1/3 through the parenthesis:
1/4x + 3/2 + 1/8x - 3/8= 1/3x + 4/3
Subtract the fractions.
1/4x + 9/8 + 1/8x= 1/3x + 4/3
Multiply both sides of the equation by 24.
6x + 27 + 3x= 8x + 32
Collect the like terms:
9x + 27= 8x + 32
Move 8 to the left side, then change the sign.
9x - 8x + 27= 32
Move 27 to the right side, the. change the sign.
9x - 8x= 32 - 27
Collect the like terms.
x= 32 - 27
Subtract the numbers.
32 - 27 = 5
Solution: x = 5
If you look at the data, you can see that every y value is opposite to the corresponding x- value.
So, equation can be written as
y = [-] x or y=[-1]x
The "standard" parabola with roots 0 and 2 is
All multiples of this parabola, i.e.
have the same roots. We can choose the factor such that the parabola passes through the desided point: if we plug 1, 5 for x, y we have
So, our claim is that the parabola
has roots 0 and 2 and vertex at (1, 5).
You can easily verify this: the roots are guaranteed by the fact that we can write the equation as
The vertex must be at x=1, because it's the midpoint of the roots. Moreover, if we evaluate the function at x=1 we have
as required.
X is equal to 12
This is because 5 was multiplied and 6 making 30. So you have to multiply 2 and 6 making x 12. Hope that makes sense
