Answer:

x = 2

Step-by-step explanation:

2(2x+1-x)=6

2(x+1)=6 add common factors

2x+2=6 distribute the 2

2x=4 subrtract 2 on both sides

x=2 divide 2 on both sides

Suppose you solved a second-order equation by rewriting it as a system and found two scalar solutions: y = e^5x and z = e^2x. Th

xenn [34]

Answer:

The solutions are linearly independent because the Wronskian is not equal to 0 for all x.

The value of the Wronskian is $\bold{W=-3e^{7x}}$

Step-by-step explanation:

We can calculate the Wronskian using the fundamental solutions that we are provided and their corresponding the derivatives, since the Wroskian is defined as the following determinant.

$W = \left|\begin{array}{cc}y&z\\y'&z'\end{array}\right|$

Thus replacing the functions of the exercise we get:

$W = \left|\begin{array}{cc}e^{5x}&e^{2x}\\5e^{5x}&2e^{2x}\end{array}\right|$

Working with the determinant we get

$W = 2e^{7x}-5e^{7x}\\W=-3e^{7x}$

Thus we have found that the Wronskian is not 0, so the solutions are linearly independent.

Tammi deposited $520 into a bank account that earned simple interest each year. After 5 years, she had earned $156 in interest.

Sveta_85 [38]

Answer:

Step-by-step explanation:

Interest = Principal * rate * time

156 = 520(r)(5)

156 = 2600r

r = 0.06 or 6%

The perimeter of parallelogram WXYZ is 2 square roots of 26+ units

lord [1]

The formula for solving perimeter of a parallelogram is P=2(a+b) where "a" is for the altitude and "b" for the base. From the give figure, we can determine both a and b values as enumerated below,
a=5
b=4
We can solve for P as shown below,
P=2(5+4)
P=18 unit.
Therefore, the perimeter is equal to 18.

I hope this helps, have a great day, and God bless.
Brainliest is always appreciated :)
