Answer:
30 dollars
Step-by-step explanation:
The y-intercept is 15 and the slope is 30
How?
slope = change in y/change in x
(15x^3y^-8)÷(5x^2y^-4)
= 3xy^-4
(3x)/ y^4
The correct answer is b; they are independent because the occurrence of one does not affect the occurrence of the other.
Answer:
C
Step-by-step explanation:
For the given intervals
( - ∞, - 5) ← use any value < - 5 but not - 5, the parenthesis ) indicates that x is less than - 5 but not equal to - 5
(- 5, - 1) ← - 4, - 3, - 2 can be used but not - 5 or - 1
(- 1, 4) ← 0, 1, 2, 3 can be used but not - 1 or 4
(4, ∞ ) ← use any value > 4 but not 4
Hence
3 can be used in (- 1, 4)
- 6 can be used in (- ∞, - 5)
zero can be used in (- 1, 4)
- 5 cannot be used in any of the given intervals
