What is the length of DE

Mathematics
2 answers:
tangare [24]3 years ago

These two triangles are similar and the conversion factor is 2/3. This can be found by dividing one side length corresponding to the other on the other triangle.

In this case, DF ~ AC

DF = 12

AC = 18

12/18 = 2/3

Knowing this, we can multiply 15 by 2/3 to find the length of DE because side lengths AB and DE are similar.

15 • 2/3 = 10

DE = 10

Graph the line with slope-2/3<br> passing through the point (-5, -4),
Orlov [11]

Answer:

The figure is attached down

Step-by-step explanation:

To graph a line you must have its equation

The form of the linear equation is y = m x + b, where

  • m is its slope
  • b is the y-intercept (y at x = 0)

∵ The slope of the line is  -\frac{2}{3}

∴ y = -\frac{2}{3} x + b

- To find b substitute x and y in the equation by the coordinates

   of a point on the line

∵ The line passing through point (-5 , -4)

∴ x = -5 and y = -4

∵ -4 =  -\frac{2}{3} (-5) + b

∴ -4 = \frac{10}{3} + b

- Subtract  \frac{10}{3} from both sides

∴ -\frac{22}{3} = b

∴ y = -\frac{2}{3} x - \frac{22}{3}

To draw the line substitute x by any two values and find their ys

∵ x = -2

∴ y = -\frac{2}{3} (-2) - \frac{22}{3}  

∴ y = -6

∴ The line passing through point (-2 , -6)

∵ x = 1

∴ y = -\frac{2}{3} (1) - \frac{22}{3}  

∴ y = -8

∴ The line passing through point (1 , -8)

∵ x = 4

∴ y = -\frac{2}{3} (4) - \frac{22}{3}  

∴ y = -10

∴ The line passing through point (4 , -10)

Now we can make a table to draw the line

→  x  : -5  :  -2  :  1  :  4

→  y  : -4  :  -6  : -8 :  -10

Plot the points on the graph paper and draw the line
