Consider u = {x|x is a positive integer greater than 1}. which is an empty set? {x|x ∈ u andone-half is prime} {x|x ∈ u and 2x is prime} {x|x ∈ u andone-half can be written as a fraction} {x|x ∈ u and 2x can be written as a fraction}

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
