Answer:
(Your answer choices were really confusing, so I just put the plain answer)
Step-by-step explanation:
To find the slope of a line with just two points, we can use the formula
. In this case,
. This is
. This reduces to 
Answer:

Step-by-step explanation:
The work done is the product of the magnitude of the force applied to the object by the magnitude of the displacement of the object by the cosine of the angle between the force and direction of the displacement. This is:

In this case

|F|=180 pound force
The magnitude of vector AB is:

Finally the work is:


You cannot take the square root of a negative number so the radicals must be greater than or equal to-1.
9-10x≥0
-10x≥-9
x≤9/10
{x|x≤-10}
Answer:
17 boxes
Step-by-step explanation:
Let x be the number of boxes that you can buy.
14x = 150
x = 250 / 14 = 17.85
We cannot buy 0.85 of a box, so we can only buy 17 boxes.
Answer:
x=180-95-57 (sum of triangle)
or,x=28
