Answer:
Option d. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of an inequality, then the ordered pair must be satisfy the inequality
Verify each case
case a) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case b) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case c) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case d) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is true
therefore
the ordered pair is a solution
Answer:
D. 3y+1
Step-by-step explanation:
The coefficient is the number in front of the variable
3y has a coefficient of 3
3 ( y-6) has a factor of 3 since it is multiplied by the other term ( y-6)
If <em>f(x)</em> is a density function, then its integral over the entire real line should be 1:

so yes, <em>f(x)</em> is indeed a density function.
8 × 40 + 8 × 3
this is the expanded form
