Answer:

m=-\frac{3}{4}.

Step-by-step explanation:

We have been given coordinates of two points on a line. We are asked to find the slope of the line using given points.    

We will use slope formula to solve our given problem.

m=\frac{y_2-y_1}{x_2-x_1}, where,  

m = Slope of line,

y_2-y_1 = Difference between two y-coordinates on the line.

x_2-x_1 = Difference between two x-coordinates of the same y-coordinates.

Let (0,3)=(x_1,y_1) and (4,0)=(x_2,y_2)

Substitute coordinates of the given points in slope formula:

m=\frac{0-3}{4-0}

m=\frac{-3}{4}

m=-\frac{3}{4}

Therefore, the slope of the line passing through given points is -\frac{3}{4}.

Maria is installing gutters on her rectangular shed that measures 10 ft by 9 ft she has 23 ft of gutter already and need to purc
Paha777 [63]

Answer:

Maria needs 3 lengths of gutter of finish the shed.

Step-by-step explanation:

We need to calculate the perimeter of the rectangular shed to know how much  5 feet gutter is needed.

The perimeter of the shed is p = 2(l + b) where l = 10ft and b = 9 ft

p = 2(10 + 9) = 2(19) = 38 ft

Now, the perimeter of the shed also equal 23 ft of gutter already installed plus 5x ft gutter where x = number of gutters.

So 23 + 5x = 38

collecting like terms, we have

5x = 38 - 23

5x = 15

dividing through by 5 we have

5x/5 = 15/5

x = 15/5

x = 3

So, Maria needs 3 lengths of gutter of finish the shed.

Helga [31]

Answer:

The required proof is shown below.

Step-by-step explanation:

Consider the provided figure.

It is given that KM=LN

We need to prove KL=MN

Now consider the provided statement.

KM = LN                     Given

KM = KL+LM              Segment addition postulate

LN = LM+MN             Segment addition postulate

KL+LM = LM+MN      Substitution property of equality

KL = MN                    Subtraction property of equality

The required proof is shown above.
