Train a is traveling north at a steady speed of 70 miles per hour. after 2 hours, it is 150 miles north of hillsboro. train b is traveling north at a parallel track. it’s distance north of hillsboro is represented by the graph. where were the two trains in relation to each other when they began traveling?

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
