X/5 = 6<br> solve for x <br> A. x = 30<br> B. x - 11<br> C. x = -11<br> D. x = -30
gayaneshka [121]

The value of x is 30 which is the correct answer would be an option (A)

<h3>What are Arithmetic operations?</h3>

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operations is called the arithmetic operator.

Operators who let do basic mathematical calculations.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given expression that x/5 = 6

To determine the value of x

⇒ x/5 = 6

Solve for x

⇒ x = 6×5

Apply the Multiplication operation

⇒ x = 30

Solve the differential equation by variation of parameters.<br><br> y''+y=secx
suter [353]

Answer:y=

Acosx+Bsinx +cosx ln(cosx)+x sinx

Step-by-step explanation:

given  equation y''+y=secx

auxiliary  equation

p^2+1=0\\p=\pm i

so CF is y=Acosx+Bsinx

now

y_1(x)=cosx \ \ \ \ y_2(x)=sinx\\{y_1}'(x)=-sinx \ \ \ \ {y_2}'(x)=cosx

using wronskian formula

W=\begin{vmatrix}cosx &sinx \\ -sinx & cosx\end{vmatrix}

          =cos^2x+sin^2x=1

now f(x)=secx

u=-\int \frac{f(x)y_2(x)}{W(x)}dx \ and \ v=\int \frac{f(x)y_1(x)}{W(x)}dx

u=-\int \frac{secx\times sinx}{1}dx \ and \ v=\int \frac{secx\times cosx}{1}dx

u=-\int tanx dx \ and \ v=\int {1}dx

u=ln(cosx) \ \ \ and \ \ v=x

now particular integrals are

PI=cosx ln(cosx)+x sinx

total solution

y= C.F+P.I

y=Acosx+Bsinx +cosx ln(cosx)+x sinx

Help???????????!!!!!!!!!!!
Butoxors [25]
Salutations!

12 \frac{2}{3}

- 9 \frac{3}{4}

= \frac{38}{3} 

Then,

- 9 \frac{3}{4}

- \frac{39}{4}

Next, our final answer:

= \frac{35}{12}

= 2 \frac{11}{12} 

Our decimal would be 2.916667

Hopefully This Helps!!!

4. Find the coordinates in the table after a translation 3 units right and 4 units down followed by a reflection over the x-axis
never [62]

Answer:

translation 3 units right and 4 units down (7, -6)

reflect over x-axis (7, 6)

Step-by-step explanation:

The point is (4, -2), you translate the domain (4) 3 to the right which makes the domain 7, then translate 4 units down to get the range. The range is now -6 because -2 -4= - 6. To reflect over the x- axis, count upward from the point until you get to the 7, 0, and then count 6 more upward to get (7, 6) the point after it was reflected over the x-axis
