Answer:
f(- 2) = - 4
Step-by-step explanation:
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x) , that is
f(- 2) = (- 2)² + 3(- 2) - 2 = 4 - 6 - 2 = - 4
Answer:
k > 1 is the solution.
Step-by-step explanation:
We are given that 'Negative 5 is fewer than 6 less than a number k', so algebraically it means that - 5 < k - 6.
Then this is a linear inequality of single variable k and we have to solve it.
Now, we have
- 5 < k - 6
⇒ - 5 + 6 < k - 6 + 6 {Adding 6 to both sides}
⇒ 1 < k
⇒ k > 1
This is the solution of the given inequality. (Answer)
Area = side AB * side BC = (5x + 5x + 3)(3x + 92x - 4)
= (10x + 3)(95x - 4) = 950x^2 - 40x + 285x - 12
= 950x^2 + 245x - 12 Answer
This cannot be negative so restriction on x is 950x^2 + 245x > 12
That is x > 0.0421
