#8. evaluation the expression when x=-1 and y = 3. 5x^-6y^-2/y

            5

      x^6 y^3

Step-by-step explanation:

If x=-1 and y = 3. what is the value of 5x^-6y^-2/y?

Important:  if you're working with negative exponents, please enclose them inside parentheses:

5x^(-6) y^(-2) / y^(1)                    1

First, the y terms become   = 1 / y^3  

                                              y^2 * y

                                                               5

Then  5x^(-6) y^(-2) / y^(1)  becomes (answer)

                                                             x^6 y^3

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

it is b)

hope this : )
