If y varies directly with x and y = 5 when x = 4, find the value of y when x = -8

Help me and show your work.
astraxan [27]

Answer:

x = 5/6

Step-by-step explanation:

From the question, we are told that the value of the perimeter equals the value of the area

mathematically, the area of a rectangle is the product of its side lengths

we have this as;

5 * 4x = 20x

The formula for the perimeter is;

P = 2(l + b)

P = 2(5 + 4x)

So we equate this to the area above

20x = 2(5 + 4x)

20x/2 = 5 + 4x

10x = 5 + 4x

10x - 4x = 5

6x = 5

x = 5/6
