The second equation is already solved for y, so we substitute it into the first equation.

x + 6y = 6

x + 6(1/3 x - 2) = 6

x + 2x - 12 = 6

3x = 18

x = 6

Now substitute 6 for x in the second original equation and solve for y.

y = 1/3 x - 2

y = 1/3 * 6 - 2

y = 2 - 2

y = 0

Answer: x = 6 and y = 0

Triangle JKL was translated 12 units vertically and then reflected over the y-axis to create triangle J'K'L' What is the value o

vova2212 [387]

Answer:

B. 6

Step-by-step explanation:

The picture of the question in the attached figure

we know that

A translation and a reflection are rigid transformations, that produce congruent figures'

Remember that

Two figures are congruent if their corresponding sides and their corresponding angles are congruent

In this problem

Triangle JKL and Triangle J'K'L' are congruent

$JL=J'L'$

substitute the given values

$8=2x-4$

solve for x

$2x=8+4\\2x=12\\x=6$

if the ratio of the areas of 2 similar polygons is 32:50, what is the ration of the corresponding side lengths?

Lera25 [3.4K]

$\bf \qquad \qquad \textit{ratio relations}
\\\\
\begin{array}{ccccllll}
&Sides&Area&Volume\\
&-----&-----&-----\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}&\cfrac{s}{s}&\cfrac{s^2}{s^2}&\cfrac{s^3}{s^3}
\end{array} \\\\
-----------------------------\\\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}=\cfrac{\sqrt[3]{s^3}}{\sqrt[3]{s^3}}\\\\
-------------------------------\\\\$

$\bf \cfrac{small}{large}\qquad \cfrac{s}{s}=\cfrac{\sqrt{s^2}}{\sqrt{s^2}}\implies \cfrac{s}{s}=\cfrac{\sqrt{32}}{\sqrt{50}}\implies \cfrac{s}{s}=\cfrac{\sqrt{16\cdot 2}}{\sqrt{25\cdot 2}}
\\\\\\
\cfrac{s}{s}=\cfrac{\sqrt{4^2\cdot 2}}{\sqrt{5^2\cdot 2}}\implies \cfrac{s}{s}=\cfrac{4\sqrt{2}}{5\sqrt{2}}\implies \cfrac{s}{s}=\cfrac{4}{5}$

Simplify the following 7 times the square root of 54 - 2 times the square root of 24

EleoNora [17]

The first step for solving this problem is to simplify the radical
7 $\sqrt{54 - 2}$ x 2√6
Calculate the product
14 $\sqrt{(54 - 2) X 6}$
Subtract the numbers
14 $\sqrt{56 x 6}$
Simplify the radical
14 x 2 $\sqrt{13 x 6}$
Multiply the numbers
14 x 2√78
Finally,, calculate the product for your final answer
28√78
