Answer:
4x + 3y = 5
Step-by-step explanation:
Given
y - 11 = - 
(x + 7)
Multiply through by 3
3y - 33 = - 4(x + 7) ← distribute
3y - 33 = - 4x - 28 ( add 4x to both sides )
4x + 3y - 33 = - 28 ( add 33 to both sides )
4x + 3y = 5
Answer:
When a point is reflected across the y-axis, the y-coordinate(s) remain the same. But the x-coordinate(s) is transformed into opposite signs.
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.
