In the past 4 years, a sporting goods store had two yearly losses of $140,000 and $56,000 and two yearly profits of $110,000 and $60,000.
what was the net profit or loss over 4 years?
a.
$196,000
b.
$26,000
c.
$170,000
d.
–$26,000

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
