Answer:
C. -6 and -9
Step-by-step explanation:
For the polynomial to be zero, one or more of the factors must be zero. For the factors to be zero, we require ...
x +6 = 0
x = -6 . . . . . . subtract 6 from both sides of the equation
and likewise, ...
x +9 = 0
x = -9 . . . . . . subtract 9 from both sides of the equation
x = -6 or -9 will make the polynomial zero.
Answer:

$400hours fee+$400 initial fee=$800 total payment
Answer:
Option D 
and 
Step-by-step explanation:
step 1
<u>Find the equation of the inequality A</u>
we know that
The solution of the inequality A (dashed line) is the shaded area below the dashed line
The equation of the dashed line is 
therefore
The equation of the inequality A is
step 2
<u>Find the equation of the inequality B</u>
we know that
The solution of the inequality B (solid line) is the shaded area below the solid line
The equation of the solid line is 
therefore
The equation of the inequality B is
The system of linear inequalities is
and
The daughter will be 24 and the mother would be 48 because 24*2=48.
and are there any answer for the second question
Answer:
Yes
Step-by-step explanation:
Given that In my data set of 10 exam scores, the mean turned out to be the score of the person with the third highest grade.
No two people got the same score.
Let the scores be a,b,c,d,e in ascending order where no two scores are equal
If a+b=d+e =2c then we can have c as the mean of the scores of 5 persons
This is because
Total sum = a+b+c+d+e = (a+b)+c+(d+e)
= 2c+c+2c=5c
Average= 5c/5 = c
It makes sense and there are chances as long as the above condition is satisfied.
