Answer:

8.5 inches

Step-by-step explanation:

First let's find the time t when the depth of the snow is 7 inches.

To do this, we just need to use the value of D = 7 then find the value of t:

7 = 1.5t + 4

1.5t = 3

t = 2\ hours

We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:

D = 1.5*3 + 4

D = 4.5 + 4 = 8.5\ inches

The depth of snow one hour from now will be 8.5 inches.

What is the slope of the line represented by the equation y=x/3-5
Nana76 [90]

Answer:

a. 1/3

Step-by-step explanation:

y=x/3-5  (rewrite x - term)

y = (1/3) x + 5

recall that in the slope-intercept form of  a linear equation y = mx + b

m is the slope.

In our case, we can clearly see that slope  m = (1/3)
