Question

On Monday morning there were 15 inches of snow on the ground. the temperature warmed up and by Tuesday morning 36 inches had melted three
more inches melted by Wednesday morning and the pattern continued until no more snow was left

what is the best function
quadratic f(x)=-2x^{2} +5x+15
quadratic f(x)=2x^{2} +15
linear f(x)=-2x
linear f(x)=-3x+15

How long until all the snow is melted
5 days
6 days
8 days
15 days

Answer 1

Answer:

linear function, f(x)=-3x+15

Step-by-step explanation:

its ez

Answer 2

Answer:

X= Days after Monday y= Inches of snow left

Linear= f(x)=-3x+15

5 days

Step-by-step explanation:

X= Days after Monday because you want to see how much Snow is being lost at the rate of 3

5 Days= 15-3=12, 12-3=9, 9-3=6, 6-3=3, & 3-3=0
