Add and subtract the rational expressions. which statements are true about the process for adding and subtracting the rational expressions? check all that apply. the expression is not defined when x = –1. the first step in the simplification is . the denominator of the fully simplified expression will be x – 1. the numerator of the fully simplified expression will be –3x. the numerator of the fully simplified expression will be –3x + 10.

what?

step-by-step explanation:

what do you need with. i love quadrants. can you tell me ?

i think it is c, not positive though

step-by-step explanation:

-2 is the right

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
