The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Profit is the difference between revenue and cost. Given that:
R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3
P(r) = R(r) - C(r)
P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4

The cost would be $31.50 because in this case 30% is 13.5.
Answer:
y+6=-3/4(x-2)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=-3/4(x-2)
y+6=-3/4(x-2)
Answer:
You can do this. It's actually pretty simple
Step-by-step explanation:
You are given 3 hours. and you re told 5 kph or kilometres per hours.
3 replaces the x variable. You can take it from there and for sure you'll get the answer you want for y
