Using data for the years 1985 to 1990, the function y = 9x + 10.8 can be used to estimate the first trend, while the function y = 5.5x + 30 can be used to estimate the second trend. For both functions,
x is the number of years since 1985. If these trends continue, in what year are the two trends
equal?

heyyy

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
