Question

read the description of a proportional relationship. in a flash of sheer brilliance, jaylen invents a time machine! the machine uses a small nuclear reactor to generate the electricity it needs to travel back in time. there is a proportional relationship between how many years jaylen wants to travel back in time, x, and how much electricity (in megawatts) his time machine needs, y. the equation that models this relationship is y = 2x. how much electricity does jaylens time machine need to travel back 10 years? write your answer as a whole number or decimal. megawatts

Explanation:

Step1: Identify the given values

We know $x = 10$ (years to travel back) and the equation $y = 2x$.

Step2: Substitute the value of x

Substitute $x = 10$ into $y = 2x$, so $y=2\times10$.

Step3: Calculate the result

$y = 20$.

Answer:

20
