Nina [5.8K]

Step-by-step explanation:

Let y1 and y2 be (e^x)/2, and (xe^x)/2 respectively.

The Wronskian of them functions be

W = (y1y2' - y1'y2)

y1 = (e^x)/2 = y1'

y2 = (xe^x)/2

y2' = (1/2)(x + 1)e^x

W = (1/4)(x + 1)e^(2x) - (1/4)xe^(2x)

= (1/4)(x + 1 - x)e^(2x)

W = (1/4)e^(2x)

Since the Wronskian ≠ 0, we conclude that functions are linearly independent, and hence, form a set of fundamental solutions.

What is 710-35w=570-25w
Vikentia [17]

Answer:

w=14

Step-by-step explanation:

Let's solve your equation step-by-step.

710−35w=570−25w

Step 1: Simplify both sides of the equation.

710−35w=570−25w

710+−35w=570+−25w

−35w+710=−25w+570

Step 2: Add 25w to both sides.

−35w+710+25w=−25w+570+25w

−10w+710=570

Step 3: Subtract 710 from both sides.

−10w+710−710=570−710

−10w=−140

Step 4: Divide both sides by -10.

−10w

−10

=

−140

−10

w=14

Write the equation of a line in point-slope form whose slope is 7 and passes through the point (7, -2).
horrorfan [7]

Answer:

Step-by-step explanation:

m=7

So by using point slope form

y-y1=m(x-x1)

y-(-2)=7(x-7)

y+2=7x-49

y-7x+51=0
