The expression 1.5t + 20 predicts the height In centimeters of a plant t days from today. What is the predicted height of the plant 5 days from today?

Respuesta :

you would replace the t with 5 because t = days

1.5(5) + 20 = 7.5 + 20 = 27.5

Answer:

27.5 centimeters

Step-by-step explanation:

20 is your y-intercept so its how tall the plant is currently.

1.5 is how much your plant is growing in one day.

So just do 1.5 · 7 to find out how much the plant will grow in 7 days

1.5 · 5 = 7.5

then add how much the plant has grown to the plant's height

7.5 + 20 = 27.5

OR

since 5 = t you could replace t with 5

1.5(5) + 20 = 27.5
