It would be D. You can find this answer by located 0 on the x axis and then finding where the y value is according to the x value.
Answer: which is the same as
If the math notation does not load properly, or the font size is too small, then it says ( (x+4)(x-1) )/( (x+4)(x+2) ) which is the same as (x^2+3x-4)/(x^2+6x+8)
==========================================================
Explanation:
We see that x cannot equal -2, as this prevents the denominator (x+2) from becoming zero. If x = -4, then x+4 = 0. So x not allowed to be -4 means (x+4) is prevented in being zero, and this is the missing factor in the denominator. We can never divide by zero.
Multiply top and bottom of this given fraction by (x+4) to get
Note how the (x+4) terms divide and cancel to get back to the original fraction given. The portion sticks around to make sure the domains line up properly.
----------
Optionally you can expand out each product in the numerator and denominator to get
(x+4)(x-1) = x^2-x+4x-4 = x^2+3x-4
(x+4)(x+2) = x^2+2x+4x+8 = x^2+6x+8
I used the FOIL rule
So,
Answer: a. x=8,-6 b.t=-2,-3 c. x=3,-10
Step-by-step explanation: your basicly solving for x but u can also use it math
its free and online i use most of the time and it helps hope this helps you
Answer:
4xy + 6x
Step-by-step explanation:
2xy + 2x + 4x + 2xy
combine like terms:
4xy + 6x
Yes 0 is a positive number ! :)
