Y = 5x + 2
y = 3x
5x + 2 = 3x
- 5x - 5x
2 = -2x
-2 - 2
-1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)
y = 3x
5x + 2 = 3x
- 5x - 5x
2 = -2x
-2 - 2
-1 = x
y = 3x
y = 3(-1)
y = -3
(x, y) = (-1, -3)

Answer:
The ratio of the intensities is roughly 6:1.
Step-by-step explanation:
The intensity I() of an earthquake wave is given by:
<em>where P: is the power ans d: is the distance. </em>
Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:
<em>where I₁ = P/4πd₁², d₁=19 km, I₁ = P/4πd₂² and d₂=46 km </em>
Therefore, the ratio of the intensities is roughly 6:1.
I hope it helps you!
