Answer:
Cost of each individual book = $10.5
Step-by-step explanation:
Given:
Cost of 3 book set = $24.81
Amount save = $6.69
Find:
Cost of each individual book
Computation:
Assume:
Cost of each individual book = a
Total cost = 3a
So,
Total cost = $24.81 + $6.69
Total cost = $31.5
So,
3a = $31.5
a = $10.5
Cost of each individual book = $10.5

f(x) = x² + 14 g(x) = x - 2 -1 ? I think it means evaluate when x = -1
Find (f(x) + g(x)) when x = -1
(f(x) + g(x)) = [ ( x² + 14) + (x - 2)] insert f(x) and g(x)
= [ x² + x + 14 - 2] add like the term
(f(x) + g(x)) = x² + x + 12
(f(-1) + g(-1)) = (-1)² + (-1) + 12 evaluate at x = -1
= 1 - 1 + 12
= 12
I can't really answer that. Sorry. But I know a YouTube account that can help you. Search up L. Moon and it will show you a list of videos.
