Answer:
an = -18 +11(n -1)
Step-by-step explanation:
We notice that the first term (a1) is -18, and the common difference (d) is -7-(-18) = 11. Filling these values into the form for the explicit formula gives ...
an = a1 +d(n -1)
an = -18 +11(n -1)
Answer:
f(g(x)) = 7x + 27
Step-by-step explanation:
We have, f(x) = 7x+13 and g(x) = x+2.
So, the function f(g(x)) is obtained by substituting the function g(x) = x+2 in f(x) = 7x+13,
i.e. f(g(x)) = f(x+2)
i.e. f(g(x)) = 7 × (x+2) + 13
i.e. f(g(x)) = 7x + 14 + 13
i.e. f(g(x)) = 7x + 27
Thus, f(g(x)) = 7x + 27
It would be better to buy the 8 bags because each bag costs 0.57 and the 5 bags cost 0.58 u divide the cost into the number of bags.
