Abean plant grows at a constant rate for a month. after 10 days, the plant is
35 centimeters tall. after 20 days, the plant is 55 centimeters tall.

which equation models the height of the plant, y, after x days?

a. y+35 = 2(x+10)

b. y - 35 = 2(x - 10)

c. y - 10 = 2(x - 35)

d. y - 35 = 1/2 (x - 10)

B. y - 35 = 2(x - 10)

Step-by-step explanation:

The height of the plant, y, after x days could be modeled by the equation

y-y0=k(x-xo)     (1),where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.From equation (1), k could be evaluated as follows:k=(y-y0)/(x-x0) From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.Thus,k=(55-35)/(20-10)=2Therefore, the model equation becomesy-35=2(x-10)

Idon’t feel like doing the math but you need to do 2.24 divided by 7
