Answer:
4x + 4
Step-by-step explanation:
F(x) = 2x - 1
G(x) = 3x + 2
H(x) = x²
We have to calculate the expression F(G(x)) - F(x)
F(G(x)) means the composition of functions F(x) and G(x). In order to find F(G(x)) we have to replace ever occurrence of x in F(x) with the value of G(x). So,
F(G(x)) = 2(3x+2) - 1 = 6x + 4 - 1 = 6x + 3
Thus,
F(G(x)) - F(x) = 6x + 3 - (2x - 1)
= 6x + 3 -2x + 1
= 4x + 4
Therefore, the expression F(G(x)) - F(x) equals 4x + 4
Answer:
0.9
Step-by-step explanation:
because if you multiply 0.9 by 5 it equals 4.5, why?
well 0.9 isn't a full number it's not even 1!
If you multiply
5 × 1 = 5
so if you multiply what's smaller than 1 by 5
5 × 0.9 = 4.5
Hope this helps!
Have a nice day!

I think it would just be (if 7 is x and 14 is y like a table where every 2 are a pair) 2x so the next number in the sequence would be 28
