The graph below shows the prices of different numbers of sunglasses at a store: which equation can be used to determine p, the cost of s sunglasses? haha..

we can see that

curve is a straight line

y-axis is price(p)

x-axis is number of glasses (x)

so, firstly we will find slope

we can select any two points

(0,0) and (2,9)

x1=0, y1=0 , x2=2 , y2=9

now, we can plug values

now, we can use point slope form of equation

so, we can plug it

now, y is p

so, we get our equation as

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
