<em>Greetings from Brasil... </em>
For the composite function FоG(X) = F(G(X)), just replace the function G(X) in the X of F(X):
F(X) = X + 4
G(X) = 3X² - 7
F(X) = X + 4
F(G(X)) = [G(X)] + 4
F(G(X)) = [3X² - 7] + 4
F(G(X)) = 3X² - 7 + 4
<h2>F(G(X)) = 3X² - 3</h2>
Look for patterns between the numbers first and see where it goes...
3, -6, 12, 4, 20 ((distance between 3 and - 6 is -9)
-9 +18 -8 +16 (let's continue the pattern )
20, 13, 27, 21, 33.......
-7 +14 -6 +12
Answer:
D. 36.75-3x
Step-by-step explanation:
You have a total amount of 36.75.
Since you are spending money you need to subtract.
We know that Marshall buys 3 tickets.
We also know that 'x represents the amount of a single ticket.
Remember that they are asking you for an algebraic expression and not an equation.
So you need to take away from your total, 36.75. And since you plan on buying three tickets and aren't given the amount x it leaves you with taking 3x from your total 36.75 or an other words
D. 36.75 - 3x
Multiplication. In the case of 2x, you multiply x by 2.
What fraction is equivalent to the whole number 6?
Well, any fraction which result gives you 6 is a fraction that would fulfill the requirement, I'll give you a few examples so you can grasp the idea:
6 = 6/1 = 12/2 = 18/3 = 24/4 = 30/5 = 36/6 = 42/7 = 48/8 = 54/9 = 60/10
etcetera
