F(x) = -5x g(x) = 8x^2 - 5x - 9 find (f•g)(x)

Mathematics
1 answer:
Stells [14]3 years ago
6 0

Answer:

B

Step-by-step explanation:

You are making composite functions, since all the answers provided dont fit, I only suggest to clearify that the lone term in the B option, is actually 45x and not 45.

If this is the case, composite functions means that you eval the expresion g(x) in every x variable found in f(x).

Using this, it gives you that f(g(x))= -40x^{2} +25x+45

(1+i)^2(x+yi)=4+5i<br> Solve for x and y
faust18 [17]

Answer:

x = 5/2

y = -2

Step-by-step explanation:

(1+i)² (x+yi) = 4+5i

(1+2i+i²)(x+yi) = 4+5i

(1+2i-1)(x+yi) = 4+5i

2i(x+yi) = 4+5i

2i²y + 2xi = 4+5i

-2y + 2xi = 4 + 5i

By comparing both sides,

-2y = 4

y = -2,

2x = 5

x = 5/2
