Answer:
The vertex (h,k) is (-4,-7).
Step-by-step explanation:
I assume you are looking for the vertex .

Anyways if you compare to
, you should see that
.

Answer:
Hence, the correct option is 82%.
Step-by-step explanation:
Consider the provided information.
In your university nursing program the ratio of students who scored a grade of A vs B vs C on the final exam is 12:29:9.
We need to find the percentage of student who scored a grade of "B" or higher.
Let x is the common factor for the proportion.
Then, the number of students who got grade A is 12x
The number of students who got grade B is 29x
The number of students who got grade C is 9x.
Thus the total number of students = 12x+29x+9x = 50x
The percentage of student who scored a grade of "B" or higher:
12x+29x = 41x
Hence, the correct option is 82%.
