I need help with this question :/
Setler79 [48]

Answer:

see explanation

Step-by-step explanation:

Note there is a common ratio between consecutive terms of the sequence, that is

- 450 ÷ 15 = 13500 ÷ - 450 = - 405000 ÷ 13500 = - 30

Thus to obtain the next term in the sequence multiply the previous term by - 30

start with 15 and multiply by - 30

If f(x) = 2x - 1 and g(x= 3x + 5, what is f(g(-3))?
In-s [12.5K]

Answer:

The answer to this question is -21.

Step-by-step explanation:

f(g(-3)) says "f at g at -3".

"Evaluating  the value of g if x is -3, Then put the value of  x into the f function".

g(x) = x - 4

g(-3) = 3x +5

g(-3)=3*(-3)+5

g(-3)=-15+5

g(-3)=-10.

put -10 into the f.

f(x)=2x-1

f(-10)=2*(-10)-1

f(-10)=-20-1

f(-10)=-21.

so f(g(-3))=-21.
