Answer:

y=\frac{10}{7}x+\frac{8}{7}

Step-by-step explanation:

Slope-intercept formula:

y=mx+b

Isolate y on one side:

10x - 7y = -8

\frac{10x}{7} -\frac{7y}{7} =\frac{-8}{7}               divide everything by 7 since 7 is the number next to y

\frac{10x}{7} -y =\frac{-8}{7}

We can't simplify it any further, so let us rearrange it.

y=\frac{10x}{7}-\frac{-8}{7}                According to the formula, y=mx+b, the y is first

y=\frac{10}{7}x+\frac{8}{7}

Therefore, y=\frac{10}{7}x+\frac{8}{7} is the slope-intercept form.

A 50-gal tank initially contains 20 gal of pure water. Salt- water solution containing 0.5 lb of salt for each gallon of water b
icang [17]

Answer:

x(15) = 21 lb

Step-by-step explanation:

Rate of change in volume of salt water solution = rate of volume incoming - rate of volume outgoing

                                dV/dt  = 4 - 2 =2gal/min

So, the equation for volume at cetain time t at given conditions and values becomes,

                                V(t) = 2t + V

                                V(t) = 2t + 20   gal-------------------euqation (1)

Rate of change in amount of salt = rate of salt in - rate of salt out

                                  dx/dt = {0.5*4} - {[x(t)/V(t)]*2}

                                  dx/dt = 2-2[(x(t))/(2t+20)]

                                  dx/dt = 2-[(x(t))/(v(t))] lb/min

Now, with integrating factor, we get

          exp[∫(1/(1+10))dt)] = t+10

the equation becomes

(t + 10)*x' + x = 2*(t+10)

((t+10)*x') = 2*(t+10)

(t+10)*x = t² + 20t + C

As x(0) = 0,

x(t) = (t²+20t)/(t+10)

x(15) = (15²+20*15)/(15+10)

x(15) = 21 lb
