Which of the following correctly describes the domain of the function shown below? r(x)=2x/x^2-1
A. all real numbers
B. x≠1
C. x≠+-1
D. x≠0

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

step-by-step explanation:

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer: c

(2, -4)

goes 7 to the

(9, 4)
