The image is an example of which type(s) of symmetry
LiRa [457]

Answer:

A. Both rotational and reflectional.

Step-by-step explanation:

We have been given an image of a regular polygon. We are asked to determine type(s) of symmetry for our given polygon.

Upon looking at our given polygon, we can see that it is a pentagon.

We know that a regular pentagon has five equal sides and five lines of symmetry.

We can see that each line of symmetry divides pentagon into two mirror images, therefore, our given pentagon has reflectional symmetry.

We know that the regular polygon has a rotational symmetry. We can find rotational symmetry of a regular polygon by multiplying 360 degrees by number of sides.

\text{Rotational symmetry of pentagon}=\frac{360^{\circ}}{5}

\text{Rotational symmetry of pentagon}=72^{\circ}

Therefore, a regular pentagon has rotational symmetry.

Write an equation of the line through (-1,-5) having slope 2/3. give the answer in standard form.
jekas [21]

keeping in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

\bf (\stackrel{x_1}{-1}~,~\stackrel{y_1}{-5})~\hspace{10em} \stackrel{slope}{m}\implies \cfrac{2}{3} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-5)}=\stackrel{m}{\cfrac{2}{3}}[x-\stackrel{x_1}{(-1)}]\implies y+5=\cfrac{2}{3}(x+1)

\bf \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{3}}{3(y+5)=3\left( \cfrac{2}{3}(x+1) \right)}\implies 3y+15 = 2(x+1) \implies 3y+15=2x+2 \\\\\\ 3y=2x-13\implies -2x+3y=-13\implies 2x-3y=13
