It would be 5 left handed, you have to cross multiply so \frac{1}{4} =  \frac{x}{20} then you cross mult. to get 4x=20 then divide 4 on both sides.

How do you graph and translate a shape ​
jeka94

See in the explanation

<h2>Explanation:</h2>

Translating a shape is part of that we called Rigid Transformations. This is called like this because the basic form of the shape doesn't change. So this only changes the position of the chape in the coordinate plane. In mathematics, we have the following rigid transformations:

  • Horizontal shifts
  • Vertical shifts
  • Reflections

Horizontal and vertical shifts are part of translation. So the question is <em>How do we graph and translate a shape?</em>

To do so, you would need:

  1. A coordinate plane.
  2. An original shape
  3. Set the original shape in the coordinate plane.
  4. A rule
  5. The translated shape

For example, the triangle below ABC is translated to form the triangle DEF. Here, we have a coordinate plana and an original shape, which is ΔABC. So this original shape has three vertices with coordinates:

A(-4,0)

B(-2, 0)

C(-2, 4)

The rule is <em>to translate the triangle 6 units to the right and 1 unit upward. </em>So we get the translated shape ΔDEF with vertices:

D(2,1)

E(4, 1)

F(4, 5)
