Answer:

Therefore,

(-2)^{3}=-8

Step-by-step explanation:

Simplify

-2^3

(-2)^{3}

It is read as negative 2 raised to the power three,

also it is the cube of negative 2

we know that a^{3}given as

a^{3}=a\times a\times a

so for negative a i.e -a

(-a)^{3}=-a\times -a\times -a

substituting a = 2 we get

(-2)^{3}=-2\times -2\times -2

negative sign multiplied by odd number of times then the sign remains negative.

Therefore,

(-2)^{3}=-8

Don’t save the answer and I really need help
Ksju [112]

9514 1404 393

Answer:

  zero solutions

Step-by-step explanation:

The first inequality has a boundary line with a slope of 3 and a y-intercept of 9. Shading is above the boundary line.

The second inequality has a parallel boundary line with a slope of 3 and a y-intercept somewhat lower, at -1. Shading is below this boundary line.

There is a gap between the shaded areas, so no points will be solutions to both inequalities.

The variables x and y have a proportional relationship: when x is 5, y is 8.
Alenkasestr [34]

Answer:

1.6

Step-by-step explanation:

Since y = 8

And x = 5,

You divide both values by the X Value

8 divided by 5 = 1.6

5 divided by 5 = 1

the ratio is 1:1.6

So the constant is 1.6
