There not the same
vectors have magnitude and direction scalars on the other hand only have magnitude
Answer:
I think like expressions you use x or y or such many variables. you use - or + too. like (x+2)y there are parentheses too.
Answer:
(f+g)(x) = 60x + 400
Step-by-step explanation:
Given :
Amount in account A:
f(x) = 20x + 100
Amount in account B :
g(x) = 40x + 300
Total amount in Account A and B:
f(x) + g(x) = (20x + 100) + (40x + 300)
(f+g)(x) = (20x + 40x) + (100 + 300)
(f+g)(x) = 60x + 400
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
6.2 is not a whole number
150/3 = 50 = a whole number
25 and 13 are whole numbers.
