Fisrst one is just add the functions
(f+g)(x)=f(x)+g(x)=
8x^2+16x+6+x^3-3x^2-9=
(f+g)(x)=x^3+5x^2+16x-3
multiply
ok
f(x)g(x)=(x^3-4x+2)(x^2+2)
just multiply and expand yourself because I don't have my graphing calculator with me right now
Answer:
B. (-1,2) and (-5,-2)
Step-by-step explanation:
Substitute x + 3 in for y in the second equation. you get
(x + 1)(x + 5) = 0
x + 1 = 0 or x + 5 = 0
x = - 1 or x = -5
Using the first equation, let x = -1 and x = -5 in order to get the corresponding values for y
y = -1 + 3 = 2 and y = -5 + 3 = -2
So, B is the correct answer.
14.5 × 3.14 should give you your answer
Miku would drink 4.5 ounces of water in an hour
What is the system that you have to solve to find the value of x and y?
