Evan is getting ready for his shift at the Grateful Dead concert T-shirt stand that sells only rainbow tie-dye shirts and dancing bears shirts. He has to make at least 15 shirts. Each rainbow tie-dye shirt takes 3 minutes to make and each dancing bears shirt takes 5 minutes to make, but he has only up to one hour to make these shirts. Write a system of inequalities for the situation. and how to graph​

explanation:

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)
