What is the equation written in vertex form of a parabola with a vertex of (-5, -4) that passes through (-7,8)? A y = (x + 5)2 - 4
B. y = 3(x + 5)2 - 4
C. y = 3(x + 7)2 + 8
D. y = (x - 5)2 - 4

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

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)

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
