Hey You!

40*45% = 18

40 - 18 = 22

40*56% = 22.4

x-3 and x+5 we can't do anything with so next
5(x-3)=5x-15

2(x+5)=2x+10

5x-15+2=5x-13

(2x+10-9)=2x+1

(5x-13)-3(2x+1)
-3(2x+1)=-6x-3

5x-13-6x-3=-x-16

4(-x-16)=-4x-64

the answer is -4x-64

Pls help I'm bad at math v.v<br><br> Lines m and n are parallel.
Eva8 [605]

Answer:

The measure of angle 1 is 55.

Step-by-step explanation:

The top angle= 75 because of the vertical angle theorem

The right angle= 50 because of the alternate exterior angle theorem

75+50=125

There are 180 degrees in a triangle so the angle has to equal 55

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
