(a) fill in the venn diagram below, given that:
x = {n, i, c, o, l, a}
y = {s, o, p, h, i, a}
(b) write down a subset of x that has 2 elements, and that is also a subset of y.

Write the expression in complete factored form. 5n_(c - 3) - n(c - 3) =

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
