I need help on this problem is the answer A
vladimir1956 [14]
Well, I'm not completely sure, because I don't know the formal definition
of "corner" in this work.  It may not be how I picture a 'corner'.

Here's what I can tell you about the choices:

A).  (0, 8)
This is definitely a corner of the feasible region.
It's the point where the first and third constraints cross.
So it's not the answer.

B).  (3.5, 0)
This is ON the boundary line between the feasible and non-feasible
regions. But it's not a point where two of the constraints cross, so
to me, it's not what I would call a 'corner'.

C).  (8, 0)
Definitely not a corner, no matter how you define a 'corner'.
This point is deep inside the non-feasible zone, and it doesn't
touch any point in the feasible zone. 
So tome, this looks like probably the best answer.

D).  (5, 3)
This is definitely a corner.  It's the point of intersection (the solution)
of the two equations that are the first two constraints. 

The feasible region is a triangle.
The three vertices of the triangle are  (0,8) (choice-A), 
(0,-7) (not a choice),  and  (5,3) (choice-D) .
region is a triangle

Mr and mrs Jackson have 14 grandchildren. Find the ratio of girls to boys if there are four more girls than boys
natulia [17]

Answer:

5 boys to 9 girls

Step-by-step explanation:

Let x = the number of boys

Boys = x

Girls = x + 4

x + (x + 4) = 14

2x + 4 = 14

2x = 10

x = 5

This means that there are 5 boys. Since girls = x + 4, 5 + 4 = 9. There are 5 boys and 9 girls.

I hope this helped and please mark me as brainliest!
