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
It only falls inside the trapezoid bc the circle goes through the point (0,2) so it isnt on 1.5
Answer:
75%
36= 100 16= 50% 8= 25%
Lets make percentage = P
(8x x 3x -x ) = ( P x 3x -x) 5 /1/20
= (8 *3) = P x 3 ) x 5 /1/20
reduce = P x 3 x 8 = 24 x 3 x 5 / 1/20
360/24 = 15 x 1/20
5 x 15 = 75%
Step-by-step explanation:
Answer:
23
Step-by-step explanation:
25+22+21+23+24= 115
115/5 = 23.
Answer:
x=8
Step-by-step explanation:
normally it would be 2x-1=
x+9 so now we have to combine the x into one fraction which will be 2x-1=
+9 now for my way i will be taking the -1 to the other side and when that happens its going to become positive so now the answer will be 2x=+10 ok so now we have to have the x's to the same side so i have to drag the fraction to the other side and making it positive which will conclude into 1.25x=10 and now 10 divided by 1.25 is 8 so the answer is x=8 (sorry for the ok nows) hope this helped
