Answer: Polynomials are algebraic expressions that include real numbers and variables.
Step-by-step explanation:
Division and square roots CANNOT be involved in the variables. The variables can only include ADDITION, SUBTRACTION, and MULTIPLICATION. Polynomials contain more than one term. Polynomials are the sums of monomials.
Answer:
s(x) = 10/x
Step-by-step explanation:
There are x number of people. When you divide an amount by x, you get
amount/x
Here, the amount is 10 since you bought 10 pizzas, so each person gets
10 divided by x.
s(x) = 10/x
Answer:
(x² -7)/(2x + 1)
Step-by-step explanation:
f(x) = 2x+1 and g(x) = x² -7
thus: (g/f)(x) = g(x)/f(x) = x² -7/2x + 1

Answer:
r = - 
Step-by-step explanation:
Given that r varies inversely as t , then the equation relating them is
r = 
← k is the constant of variation
To find k use the condition t = - 6 when r = - 2, then
- 2 = 
( multiply both sides by - 6 )
12 = k, thus
r = 
← equation of variation
when t = - 7, then
r = 
= -
