If y varies inversely with x and y=2 when x=5, what is the value of x when y=3?

Answers

Answer 1

Answer:

Step-by-step explanation:

Method

Inversely in this sentence means

y = k/x    

So you first step is to find the value of k. You do that by setting up an inverse relationship with y = 2 , x = 5

2 = k/5                     Multiply both sides by 5

2*5 = 5*k/5

10 = k

Now you are able to answer the question.

k = 10y = 3x = ?

y = 10/x

3= 10/x                      Multiply both sides by x

3*x = x * 10/x

3x = 10                      Divide both sides by 3

3x/3 = 10/3

x = 3.33 or x = 3 1/3

Answer

x = 3.33 or x = 3  1/3

solve for K
7K-6
2K+14

Answers

Vertically opposite angles are the same meaning u have to do:

7k-6=2k+14

U have to solve for k.

7k-6=2k+14 - using this equation

Minus 2k on both sides

5k-6=14

Add 6 on both sides

5k=20
Divide 5 on both sides

K=4 the answer is 4.

To double check substitute it into 7k-6 and 2k+14. They should be same values

7(4)-6=28-6=22
2(4)+14=8+14=22

So 4 is correct because when u substitute back into the equation it gives you the same value.

What is the approximate length of AB¯¯¯¯¯¯¯¯?

Answers

Answer

9.2 units

Step-by-step explanation:

A(-2,-2) and B(4,4) then the length is given by the distance formula

length = [tex]\sqrt{(4-(-2))^{2}+(4-(-3))^{2} }[/tex] units

           = [tex]\sqrt{6^{2}+7^{2} }[/tex] units

           = [tex]\sqrt{85\\[/tex] units

           = 9.2 units          

Answer:

AB ≈ 9.2 units

Step-by-step explanation:

calculate the length using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (- 2, - 3 ) and (x₂, y₂ ) = B (4, 4 )

AB = [tex]\sqrt{(4-(-2))^2+(4-(-3))^2}[/tex]

     = [tex]\sqrt{(4+2)^2+(4+3)^2}[/tex]

     = [tex]\sqrt{6^2+7^2}[/tex]

     = [tex]\sqrt{36+49}[/tex]

     = [tex]\sqrt{85}[/tex]

     ≈ 9.2 units ( to the nearest tenth )

Which values of x and y would make the following expression represent a real number?

Answers

The complete question is

"Which values of x and y would make the following expression represent a real number? (4 + 5i)(x + yi)"

The value of x and y are all points that satisfy the equation would be,(4,-5).

How to find the simplify the expression?

Use the distributive property to simplify the expression.

The given expression is,

(4 + 5i)(x + yi)

4(x + yi)+ 5i (x + yi)

4x + 4yi + 5xi + 5yi^2

We know that i^2 = -1

4x + 4yi + 5xi - 5y

(4x - 5y) +i (  4y + 5x)

In x+iy, x is the real part and y is the imaginary part.

If the given expression represents a real number it means the imaginary part must be zero.

4y + 5x= 0

All the points which satisfy the above equation are the values of x and y for which the given expression is a real number.

For eg. (4,-5)

4y + 5x

4(-5) + 5(4)

= 0

LHS=RHS, which means the point satisfies the equation and the value of x and y are (4,-5).
