The answer of X will be equal (3)
C - no solution
you take the second solution and times the entire equation by -1
then simply
and you get 0x + 0y = 20
Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
Answer:
the answer is 683/60
Step-by-step explanation:
just multiply 60 by 11 then add 23, or multiply the bottom number by the whole number then add the top number
M = (y₂ - y₁) / (x₂ - x₁)
Multiply each side by (x₂ - x₁): M/(x₂ - x₁) = (y₂ - y₁)
Add y₁ to each side: y₂ = M/(x₂ - x₁) + y₁
