3 0

Answer:

(-3, 0)

Step-by-step explanation:

\:  \:  \: 2x + 3y =  - 6 \\ -2x + 3y =  \:  \:  \: 6   \\   \frac{ +  \:  \:  \:  \:  \:  \:  -   \:  \:  \:  \:  \:  \: =  - }{ }{}  \\  \:  \:  \:   4x \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  - 12 \\ \\  x =  \frac{ - 12}{4}  \\  \\ x =  - 3

now,

-2( - 3) + 3y = 6 \\  6 + 3y = 6 \\ 3y = 6 - 6 \\ 3y = 0 \\ y =  \frac{0}{ 3}  \\ y = 0

thus, (-3, 0)

6 hours Zoey can expect from the tablet on a full battery charge if the battery dropped by 33%, from 100% to 67%.

<h3>What is percentage?</h3>

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

Zoey wants to use her computer tablet throughout a 6-hour flight. Upon takeoff, she uses the tablet for 2 hours and notices that the battery dropped by 33%, from 100% to 67%.

Let's suppose x hours Zoey can expect from the tablet on a full battery charge.

The value of x can be calculated using:

x = (2×100)/33

x = 200/33

x = 6.06 ≈ 6 hours

Thus, 6 hours Zoey can expect from the tablet on a full battery charge if the battery dropped by 33%, from 100% to 67%.
