(−2)³ = (-2)(-2)(-2)

Note that:

two negative numbers multiplied together results in a positive

one negative and one positive number multiplied results in a negative

Multiply:

(-2)(-2) = 4

4(-2) = -8

-8 is your answer

hope this helps

The slope of the line is m=3/4. One point is (x, 2) and (3,-4)<br> Find X
Viktor [21]

Answer:

x is 11

Step-by-step explanation:

We know the slope (3/4) and a point (3,-4), so we can use point-slope form (y-y1=m(x-x1)

Substitute the numbers into the equation

y--4=3/4(x-3)

simplify

y+4=3/4(x-3)

do the distributive property

y+4=3/4x-9/4

subtract 4 from both sides

y=3/4x-25/4

this is the equation of the line.

Since it says that (x,2) is a point in the equation, we can substitute it into the equation

2=3/4x-25/4

add 25/4 to both sides

33/4=3/4x

multiply by 4/3

11=x

we can double check by plugging (11,2) into the equation of the line.

2=3/4(11)-25/4

2=33/4-25/4

2=2

it works! :)

Hope this helps!

g100num [7]

To solve this problem, all you have to do is set the exponents equal to each other because the bases are the same.

2n=10

<em>*Divide both sides by 2*</em>

n=5


The answer is 5.


Hope this helps!
