The cost, y y , for x x pounds of nails can be represented by the equation y=3.20x y = 3.20 x . What is the constant of proportionality of the equation?

3.20

Step-by-step explanation:

If y is proportional to x as represented as;

y = 3.20x

This means that the relationship between y and x is a direct proportionality

y = kx

k is the constant of proportionality

Comparing with the given equation we will see that k = 3.20

Hence the constant of proportionality is 3.20

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
