Step-by-step explanation: Make the top x and y values times -2 to cancel all the variables and numbers out to get 0 = 0 so it would be Infinite Solutions.

And if you multiply by 2 you get the exact same equation.

If I am wrong let me know!

Hope this helps!

What is the measure of triangle X in degree

Anna11 [10]

Answer:

A.) 40°

Step-by-step explanation:

A triangle is equal to 180°

Angle X and Y has the same angle, so both have 70°.

So:

70° × 2= 140°

To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.

So:

180° - 140°= 40°

Answer= 40°

I hope this helps! :)

you bought a video game for 50$,but it loses 25% of its value every six months. how much will the video game be worth after two

castortr0y [4]

keeping in mind that two years is 24 months, and we know that cyclically it's losing 25% every 6 months.

$\bf \textit{Periodic/Cyclical Exponential Decay} \\\\ A=P(1 - r)^{\frac{t}{c}}\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{initial amount}\dotfill &50\\ r=rate\to 25\%\to \frac{25}{100}\dotfill &0.25\\ t=\textit{elapsed time}\dotfill &24\\ c=period\dotfill &6 \end{cases} \\\\\\ A=50(1 - 0.25)^{\frac{24}{6}}\implies A=50(0.75)^4\implies A\approx 15.82$
