Answer:

-z⁻⁵w²

Step-by-step explanation:

(-z⁻²w²){(z⁻²)⁻¹}

simplify each first

{(z⁻²)⁻¹}  = z⁻²⁻¹ =  z⁻³

(-z⁻²w²) z⁻³

-z⁻² z⁻³ w²)

-z⁻²⁺⁽⁻³⁾w²

-z⁻²⁻³w²

-z⁻⁵w²

Add: <br> 3x+9+8x + 12<br> 2x + 6+x² + 6x + 9
Oxana [17]

I'll treat these like they're two seperate problems because  how you set it up they're not together. If it's one whole problem please tell me and I'll solve it that way. :-)

First one: 3x+9+8x + 12

Collect like terms and simplify

(3x+8x)+(9+12)

11x+21

Second one: 2x + 6+x² + 6x + 9

Collect like terms and simplify

(2x+6x)+(6+9)+x^{2}

8x+15+x^{2}

Hope this helps you, have a BLESSED and wonderful day, as well as a safe one!

Which equation can be solved by using this system of equations?
andrew11 [14]

the equation that we can solve using the given system of equations is:

3x^5 - 4x^4 - 11x^3 + 2x^2 - 10x + 15 = 0

<h3>Which equation can be solved using the given system of equations?</h3>

Here we have the system of equations:

y = 3x^5 - 5x^3 + 2x^2 - 10x + 4

y = 4x^4 + 6x^3 - 11

Notice that both x and y should represent the same thing in both equations, then we could write:

3x^5 - 5x^3 + 2x^2 - 10x + 4 = y = 4x^4 + 6x^3 - 11

If we remove the middle part, we get:

3x^5 - 5x^3 + 2x^2 - 10x + 4  = 4x^4 + 6x^3 - 11

Now, this is an equation that only depends on x.

We can simplify it to get:

3x^5 - 4x^4 - 11x^3 + 2x^2 - 10x + 15 = 0

That is the equation that we can solve using the given system of equations.

Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You
Alex

Answer:

6 days

Step-by-step explanation:

pay 60 = -60

Let d = the number of days

30d - 60 = sister

20d = me

Equation:

30d - 60 = 20d                    Move 30 to the other side

-30d          -30d

-60 = 20d - 30d                    Combine liked terms

-60 = -10d                                

-10     -10                                Divide

d = 6
