Solve 5x - 3y = 9 for y.
LenKa [72]
5x - 3y = 9
5x = 9 + 3y
5x - 9 = 3y 
( 5x - 9 ) / 3 = y
y = ( 5 / 3x ) - ( 9 / 3 ) ( I just split the common denominator to individual parts ) 
y = 5 / 3x - 3

A submarine is only allowed to change its depth be Racing toward the surface in 60 meter stages. If the submarine starts off at
lara31 [8.8K]

Answer:

Depth = 100m

Step-by-step explanation:

Given

Initial Level = 340 m

Number of stages = 4

Difference in each stage = 60 m

Required

Determine the depth of the submarine after 4 stages

First, we have to calculate the total distance moved towards the surface of the sea;

This is calculated as

Total\ Distance = Number\ of\ Stages * Difference\ in\ each\ stage

Total\ Distance = 4 * 60m

Total\ Distance = 240m

This implies that the submarine moved a total distance of 240 metres;

It;'s new depth is calculated as follows;

Depth = Initial\ Depth - Total\ Distance

Depth = 340m - 240m

Depth = 100m

<em>Hence, its new depth after 4 stages of rising is 100m</em>

Please help!! If f (x) = e^x sin x, then f’ (x) =
shusha [124]

Answer:

f'(x) =  {e}^{x}(  \sin x + \cos x )

Step-by-step explanation:

f(x) =  {e}^{x}  \sin  x \\  \\ f'(x) = \sin x \frac{d}{dx}  {e}^{x}  + {e}^{x}  \frac{d}{dx}  \sin x \\  \\ f'(x) =  \sin x \: {e}^{x}   +{e}^{x}  \cos x \\  \\ f'(x) =  {e}^{x}(  \sin x + \cos x )
