Mathematics
1 answer:
Mariana [72]3 years ago
5 0

Answer:

400/81 cm²

Step-by-step explanation:

FE : DC

1 : 3

Since area ABCD = 400

s² = 400

s = 20

FE = ⅓(20) = 20/3 cm

IH : FE

1 : 3

IH = ⅓(20/3) = 20/9 cm

Area of HIJK:

(20/9)² = 400/81 cm²

What is the slope of the line ? ( question 1/4 )
yanalaym [24]

\huge \rm༆ Answer ༄

First Consider two points ~ (0 , -3) and (-1 , 0)

Now, use the given formula to calculate slope :

  • \sf \dfrac{y2 - y1}{x2 - x1}

  • \sf \dfrac{0 - ( - 3)}{ - 1 - 0}

  • \sf \dfrac{ 0 + 3 }{ - 1}

  • \sf \dfrac{3}{ - 1}

  • \sf - 3

Therefore, the slope of the graph is -3

Describe the graph of of the equation x = -2. Is the equation a function?
Cloud [144]
In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot. 

If x-intercept is -2 the line would be vertical as the y-intercept = 0.
