Triangle NMO has vertices at N(−5, 2), M(−2, 1), O(−3 , 3). Determine the vertices of image N′M′O′ if the preimage is reflected
Firdavs [7]

Notice that the reflection is over a line of the form x=constant; in this case, the y-coordinate of the reflected point stays the same while the x-coordinate changes as expressed by the transformation below

\begin{gathered} y\rightarrow y \\ x\rightarrow2a+x \\ where \\ x=a\rightarrow\text{ vertical line} \end{gathered}

Hence, in our case

\Rightarrow(x,y)=(2*-4-x,y)=(-8-x,y)

Transform points N, M, and O accordingly,

\begin{gathered} \Rightarrow N^{\prime}=(-8-(-5),2)=(-8+5,2)=(-3,2) \\ \Rightarrow M^{\prime}=(-8-(-2),1)=(-6,1) \\ \Rightarrow O^{\prime}=(-8-(-3),3)=(-5,3) \end{gathered}<h2>Therefore, the answer is the first option (top to bottom)</h2>

A wise man once said, “ 500 reduced by 4 times my age is 268.” What is his age?
Alla [95]

Answer:

58 years old

Step-by-step explanation:

the equation would be 500-4x=268 with x being his age.

subtract both sides by 500 to get -4x=-232

then divide both sides by -4 to get x=58
