Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k. Graph of two lines. f of x equals 1 over 3 x plus 2 and g of x equals 1 over 3 x plus 5. a.2
b.3
c.4
d.5

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

Aclassmate thinks that solving a system by graphing gives an exact answer when the lines appear to cross at a grid point, but only an approximate answer when they don't. explain why this isn't true.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
