lateral H, which transformations could have been used ?
A dilation by a scale factor of 2 followed by a reflection
A rotation followed by a dilation by a scale factor of 1/2
A reflection,a translation of 1 unit left, and then a dilation by a scale factor of 3

Answer: A translation of 6 units down a rotation and then a reflection

Step-by-step explanation:

  • The rigid transformations preserves the side length and angle measure of a figure such that figure doesn't shrink or get enlarger. It creates congruent figures.
  • There are four rigid transformations such as :

a) reflections, b) rotations, c) translations and d) glide reflection.

  • A dilation changes the size of the image when the scale factor is not equal to 1. It does not creates congruent images.

Hence, if quadrilateral H’ is congruent to quadrilateral H, then the transformation must be :

A translation of 6 units down a rotation and then a reflection.

How to break down 4/5 + 13/15 = 1 2/3
nalin [4]

Answer:

Step-by-step explanation:

The left hand side of the equation contains proper fractions while the right hand side of the equation contains mixed fraction. The mixed fraction can be changed to improper fraction. 1 2/3 becomes 5/3

To breakdown the left hand side of the equation, we would take lowest common factor of 5 and 15. It is 15

Considering 4/5, if 15 divides 5,the result is 3. Multiplying 3 by 4 gives 12. So it becomes

12/15

Considering 13/15, if 15 divides 15,the result is 1, Multiplying 1 by 13 gives 13. So it becomes

13/15

The equation becomes

(12 + 13)/15 = 5/3

25/15 = 5/3

Simplifying 25/15 to its lowest terms, it becomes 5/3 so

5/3 = 5/3

Write an equation for the following: y varies directly with x and z. Find K when x=2, y=12 and z=5.
olga_2 [115]

\qquad \qquad \textit{direct joint variation} \\\\ \textit{\underline{y} varies directly with \underline{x} and \underline{z}}~\hspace{8.5em} \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}xz~\hfill } \\\\ \textit{\underline{y} varies directly with \underline{x}, }w^2\textit{ and }z^5~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\stackrel{\downarrow }{k}xw^2z^5~\hfill } \\\\[-0.35em] ~\dotfill

y = kxz\qquad \textit{we know that} \begin{cases} x=2\\ y=12\\ z=5 \end{cases}\implies 12=k(2)(5) \\\\\\ \cfrac{12}{(2)(5)}=k\implies \cfrac{6}{5}=k~\hspace{10em}\boxed{y=\cfrac{6}{5}xz}
