Answer:

y = -1

Step-by-step explanation:

Sides marked with the same marking are congruent, so we have two equations:

3x -y = 16
2x +y = 9

Adding the equations gives ...

5x = 25

x = 5 . . . . . . divide by 5

Then the second equation tells us ...

y = 9 -2x = 9 -2(5) = -1

The value of y is -1.

Which is the value of this expression when j = negative 2 and k = negative 1?

Natalija [7]

Answer:

Option A.

Step-by-step explanation:

It is given that

$j=-2, k=-1$

The given expression is

$\left(\dfrac{jk^{-2}}{j^{-1}k^{-3}}\right)^3$

Substitute the given values in the above expression.

$\left(\dfrac{(-2)(-1)^{-2}}{(-2)^{-1}(-1)^{-3}}\right)^3$

$\Rightarrow \left(\dfrac{(-2)(1)}{\dfrac{1}{-2}(-1)}\right)^3$

$\Rightarrow \left(\dfrac{-2}{\dfrac{1}{2}}\right)^3$

$\Rightarrow \left(-4\right)^3$

$\Rightarrow -64$

Therefore, the correct option is A.
