Answer:

Step-by-step explanation:
By definition composite function would be:

Then, if g(2)=3 and f(3)=16, therefore for f(g(x)):
Yes Because 7,785 is greater than 7,742.
Toni can carry up to 5 books
1+2+3b=18
combine 1 and 2
3+3b=18
subtract 3 from both sides
3b=15
divide 3 from both sides
b=5
I'm not 100% sure what you want me to do with this but i hope this helps:
x < -3
or if you want me to flip the sign then the solution becomes
x > -3
Slope is rise over run so
(21-18)/(6-3), 3/3=1, slope is 1
plug in to find b value
18=3+b, b=15
ANSWER: y=x+15
