Sara says, "If you subtract 14 from my number and multiply the difference by - 3, the result is – 42."

Oxana [17]

Answer:

Sara's number is 28

Step-by-step explanation:

Let's assign Sara's number the variable x and solve this equation using the information provided.

"If you subtract 14 from my number"

x - 14

"and multiply the difference by - 3"

-3(x - 14)

"the result is – 42."

-3(x - 14) = -42

Now we can solve from here for x.

-3(x - 14) = -42

x - 14 = 14

x = 28

Solve nonhomogenous equation: x"+4x=cost

motikmotik

Answer:

$x(t) = Acos 2t + B sin 2t+\frac{cost}{3}$

Step-by-step explanation:

Given is a non homogeneous second degree equation as

$x"+4x=cost$

Auxialary equation is

$m^2+4 =0\\m = 2i, -2i$

Hence general solution is

x = Acos 2t + B sin 2t

Particular integral is = $\frac{cost}{D^2+4}$

Since t has coefficient 1, we substitute

$D^2 =-1\\PI = \frac{cost}{-1+4} =\frac{cost}{3}$

Hence full solution is

$x(t) = Acos 2t + B sin 2t+\frac{cost}{3}$
