Write the following as an inequality -9 is less than x, and 3 is greater than x
use x only once in your inequality

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

yes

step-by-step explanation:

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams
