I need to know the answer
Lubov Fominskaja [6]
So we know the lines are parallel.
Thus, the equation should look something like this:
y = 5x + b

Now, we have to solve for b.
Plug x=1 and y=2 into the equation to solve for b
2 = 5 + b
Subtract both sides by 5
-3 = b
b = -3

Plug that value into the equation.
y = 5x - 3

That's your answer.
Have an awesome day! :)

How you divided numbers
german

Answer:

Step-by-step explanation:

It really depend what number, or what type of number you are multiplying, it's kind of like multiplication you're just doing it backwards. Say that you were trying to divide 20 by 5 you think in your head OK five times what equals 20 and your answer would be four because 5×4 is 20 that's the easiest way to think of it that did not help you with your question tell me in the comments and I will find a better way to explain it.

The speed that a tsunami can travel is modeled by the equation s = 356 startroot d endroot , where s is the speed in kilometers
Naddika [18.5K]

The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.

<h3>What is speed?</h3>

Speed can be calculated as the ratio of distance traveled to the time taken.

The speed that a tsunami can travel is modeled by the equation

s = 356√d, where s is the speed in kilometers per hour and d is the average depth of the water in kilometers.

S = 356√d

200 = 356√d

√d = 200/356

= 0.5618

d = 0.5618^2

= 0.316 km

d = 0.32 km.

Thus, The approximate depth of water for a tsunami traveling at 200 kilometers per hour is 0.32 km.
