Answer: 4h - 6 = 70

Step-by-step explanation:

Since he is 4 times his sisters height, he is 4h. However, since he is 6 less than 4 times, he needs to subtract by 6, or -6.

Answer:

$y=200-25x$

Step-by-step explanation:

According to the problem, the initial condition is $200. If he owed $100 after 4 weeks, that means he paid $25 per week, so that would be the constant ratio. Therefore, the expression would be:

$y=200-25x$

Where $y$ represents the amount owed, and $x$ represents weeks.

So, in the 4 week, that is, $x=4$ he owed:

$y=200-25(4)=200-100=100$

As you can observe, the relation we found first perfectly to the problem. So, the final expression that model this problem is

$y=200-25x$

Answer:

The electron moved down to an energy level and has an energy of

$10.92 \times 10^{-19} \textsf{J}$

Step-by-step explanation:

$\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}$

$\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}$

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

$\triangle E=E_2-E_1$
