Find the slope of a pipe that slopes down 2/5 inch per foot.

Step-by-step explanation:

we know that

To find out the slope divide the rise by the run to calculate the slope.

Remember that

1 ft=12 in

Let

y ----> the rise

x ----> the run

m ----> the slope

we have

substitute the values

Simplify

Step-by-step explanation:

Alright, lets get started.

As per given question, pipe is inches down per feet.

1 feet = 12 inches[/tex]

Means inches

inches

So the slope will be :

Hence slope =

slope =

slope =

slope  =  :  hence the answer is :  Answer

do your own work and don"t cheat.

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
