Joseph is tracking the progress of her plant's growth. Today the plant is 8 cm high. The plant grows 1.5 cm per day What is the linear model that represents the height of the plant after d days.

y = 1.5x(or d) + 8

Step-by-step explanation:

1.5 is the slope and 8 is the y intercept(the constant term)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100
