Hey there!
First, divide both sides by 12
-12(k+4)/-12= 60/-12 and you would getk+4=5
Now subtract 4 from both sides
k+4-4= 5-4
k=-9
Answer: 4.4
Step-by-step explanation:
First you need to take 4 from both sides and then your left with 5x=22
Then you divide from both sides and you get 4.4.
That is your final answer.
Answer:
The third option
Step-by-step explanation:
The slope is a constant linear slope of 8
The Planck–Einstein relation

gives that E, the photon energy, is equal to h, Planck's constant, times <span>ν</span>, the frequency.
We can solve the equation in terms of frequency to get

We substitute our given energy,

, and Planck's constant,

.
