Answer:

a = 4/3 b

Step-by-step explanation:

2a - b = 3b – a

Add a to each side

2a+a - b = 3b – a+a

3a -b = 3b

Add b to each side

3a -b+b = 3b+b

3a = 4b

Divide each side by 3

3a/3 = 4b/3

a = 4/3 b

Answer:

a = 4/3 b

Step-by-step explanation:

2a - b = 3b – a

Add a to each side

2a+a - b = 3b – a+a

3a -b = 3b

Add b to each side

3a -b+b = 3b+b

3a = 4b

Divide each side by 3

3a/3 = 4b/3

a = 4/3 b

Solve 5y'' + 3y' – 2y = 0, y(0) = 0, y'(O) = 2.8 y(t) =( Preview
Karolina [17]

Answer:

y=\frac{4}{5}e^{t}-\frac{4}{5}e^{-\frac{2}{5}t}

Step-by-step explanation:

The given equation 5y'' + 3y' - 2y =0 can be written as

(5D^{2}+3D-2)y(t)=0

Solving for complementary function we have Roots of (5D^{2}+3D-2) as follows

(5D^{2}+5D-2D-2)

5D(D+1)-2(D+1)=0\\\\(5D-2)(D+1)=0\\\\\therefore D=-1\\D=+2/5

Thus the complementary function becomes

y=y=c_{1}e^{m_{1}t}+c_{2}e^{m_{2}t}

where

m_{1},m_{2} are calculated roots

thus solution becomes

y=c_{1}e^{-t}+c_{2}e^{\frac{2}{5}t}

Now to solve for the coefficients we use the given boundary conditions

y(0)=0\\\\\therefore c_{1}+c_{2}=0\\\\y'(0)=-c_{1}+\frac{2}{5}c_{2}=2.8\\\\\therefore c_{2}+\frac{2}{5}c_{2}=2.8\\\\c_{2}=2\\\\\therefore c_{1}=-2}

hence the solution becomes

y=-2e^-{t}+2e^{\frac{2}{5}t}

Divide this please urgent!
Sergeeva-Olga [200]

Answer:

3y² / x⁴z⁶

Step-by-step explanation:

12xy³z⁶ / 4x⁵yz¹² = 12/4 * x/x⁵ * y³/y * z⁶/z¹²

                           = 3 * 1/x⁴ * y² * 1/z⁶

                           = 3y² / x⁴z⁶
