This picture is too blurry for me to see the actual problem, but it looks like subtracting fractions, you just subtract the numerator (top number) from the other numbers' numerator, and the denominator stays the same, example:
6/8-2/8=4/8
If your teacher wants it in simplest form you just duvide the numerator and denominator by he same number, example
4/8 divided by 4/4=1/2
I just write not possible
The vertex is exactly in the middle of the two intersections with the x axis.
So, it's in the middle of x=3 and x=9.
What's the middle of 3 and 9? You can find this by calculating the average.
(3+9)/2 = 6
So, the vertex is at x = 6.
Answer:
-5
Step-by-step explanation:
4x - 1 = 6x + 9
4x = 6x + 10
-2x = 10
x = -5
B is the answer. i promise.
