8. When astronauts Antoine Weber and Rachel Sun landed on the hypothetical planet Trifour they found the inhabitants had either 3 or 4
extremities. Weber could not look at the inhabitants' faces so he just
counted their extremities. Hecounted 173 extremities. Sun, on the
other hand, could not look at their extremities so she just counted faces.
She counted 51 faces. How many inhabitants had 3 extremities? How
many were there that had 4 extremities?

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

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
