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}.

VikaD [51]

Answer:

The length of the field on the drawing is <u>55 cm</u> that is option <u>D</u>.

Step-by-step explanation:

Given:

Mark made a scale drawing of a soccer field, using a scale of .5 cm=1 m.

The actual length of the field is 110 m.

Now, to find the length of the field on the drawing.

Let the length of the field on drawing be x\ cm.

As given,

Drawing of a soccer field, using a scale of 0.5 cm=1 m.

So, 0.5 cm is equivalent to 1 m.

Thus, x\ cm is equivalent to 110 m.

Now, to get the length of the field on the drawing by using cross multiplication:

\frac{0.5}{1} =\frac{x}{110}

By cross multiplying we get:

55=x

x=55\ cm

Therefore, the length of the field on the drawing is 55 cm that is option D.

Solve the equation:<br> 5|2x-7|=20
MA_775_DIABLO [31]

Answer:

x = \frac{11}{2}, \frac{3}{2}

Step-by-step explanation:

First, isolate the absolute value:

5|2x - 7| = 20

divide both sides by 5:

|2x - 7| = 4

break into 2 equations:

2x - 7 = 4, 2x - 7 = -4

solve both equations and collect solutions:

2x = 11, 2x = 3

x = \frac{11}{2}, \frac{3}{2}
