<u>Given:</u>

Take west to be the positive direction. The height of a sloped roof above the place where you stand is 12  feet. If you move 3 feet west, the height is 10 feet.

We need to determine the slope.

Let x denote the standing place.

Let y denote the height.

Writing the given as coordinates, we get;

(0,12) and (3,10)

<u>Slope</u>:

The slope can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Substituting the coordinates (0,12) and (3,10), we have;

m=\frac{10-12}{3-0}

m=\frac{-2}{3}

Thus, the slope is m=-\frac{2}{3}

How can -6.75 + (10.25) be expressed as the sum of its integer and decimal parts
ArbitrLikvidat [17]

Answer:

 -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Here, the integer part  =     ( (-6)  + (10))

Decimal part =   ( (-0.75) + (0.25))

Step-by-step explanation:

Here, the given expression is:    -6.75 + (10.25)

Now, -6.75  = (-6)  +  (-0.75)

Also, (10.25)  = (10)  + (0.25)

So, the expression can be written as

 -6.75 + (10.25)  =  (-6)  +  (-0.75) +  (10)  + (0.25)

                           = ( (-6)  + (10))  + ( (-0.75) + (0.25))

or,   -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Where the integer part is    ( (-6)  + (10))

and the decimal part is  ( (-0.75) + (0.25))
