A comet is orbiting the sun. The equation d=130,000t represents the relationship between d, the distance traveled by the comet in kilometers and t, the time, in hours, since astronomers first spotted the comet.

What does the 130,000 in the equation tell us about the comet?

The comet will travel 130,000 kilometers in a year.

The comet is traveling at 130,000 kilometers per hour.

The comet has traveled 130,000 kilometers since astronomers spotted it.

The comet has been traveling for 130,000 hours since astronomers spotted it.

answer: ouch. thats difficult

step-by-step explanation:

yo answer should be 6 if im not mistaken

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
