Answer:
r(s(-2)) = -2
Step-by-step explanation:
We are given these following functions:


Find the value of r(s (-2)).
First we find the composition of r and s functions. It is:

At x = -2

r(s(-2)) = -2
A is the answer. I hope that helps
Answer:
B
Step-by-step explanation:
8x^2+x+3 follows the rules of being a polynomial due to the three terms being added to each other, and that they are in descending order.
Answer:
Larry's statement is correct
Step-by-step explanation:
Larry says 5 × 900 is less than 5 × 9,000.
Doni says 5 × 900 is greater than 5 × 9,000.
5 × 900 = 4500
5 × 9000 = 45,000
45,000 is greater than 4500 because the place value of 45,000 is tens thousands and 4500 is Thousands.
Hence, Larry's statement is correct.(Larry says 5 × 900 is less than 5 × 9,000.)
