If the equation is x/(x^2-4) then I will solve it here
it's rational
therefor we can't have any impossibles like dividing by zero and square root of -1 an d stuff
f(x)=x/(x^2-4)
we know that the denomenator cannot be equal to zero so the numbers you cannot user are the numbers that will make the bottom number zero
so x^2-4=0
x^2=4
x=-2 or 2
so x cannot be -2 or 2, but it can be all other numbers so
domain=all numbers except -2 and 2
Answer:
Step-by-step explanation:
1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to 
substituting the value of y in 
:
substituting x=-1 in y= -4-5x:
(upon solving, you should get this)
2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)
-1= 2 x 1 +c
-3=c
Answer:
59
Step-by-step explanation:
The answer is 59 because when you add 24 and 7 it is 31 and 31 +59 makes a 90° angle.
The correct answer is C. A statement we accept
without proof is called a postulate. It is also known as an axiom. These are rules
which are accepted to be true without any evidence that will prove these. For
instance, the postulates in the kinetic molecular theory.
