<em>A. x ≤ - 9 or x ≥ 9</em>
- Step-by-step explanation:
<em>x² ≥ 81</em>
<em>| x | ≥ 9</em>
<em>x ≥ 0 => x ≥ 9 => x ∈ [ 9 ; + oo)</em>
<em>x < 0 => x ≤ - 9 => x ∈ ( -oo ; - 9 ]</em>
<em>x ∈ ( -oo ; - 9 ] ∪ [ 9 ; + oo)</em>
It would be option A, -413
Answer:
Step-by-step explanation:
use sin formula
Answer:
A. True
B. True
C. True
D. False
Step-by-step explanation:
Option D is the only clear option that is false.
The S distribution is a statistical tool used to check the homogeneity of two independent estimates when studying population variance.
When using an F distribution, The ratio of the degree of freedom of the numerator to the denominator can be >1, = 1 or < 1.
This implies that degrees of freedom for the denominator can be smaller than the degrees of freedom for the numerator.
This makes option D false and hence the correct answer
Answer:
D, y= |x+6|
When a graph is shifted to the left, you add the shifted value to the x value in function notation.
