Simplify (4xy^-2)/(12x^(-1/3)y^-5) and Show work ...?
oee [108]
The answer is \frac{x^{4/3}y^{3}}{3}.

The fraction is: \frac{4xy^{-2} }{12 x^{-1/3} y^{-5}  }
Let's rewrite it: \frac{4xy^{-2} }{12 x^{-1/3} y^{-5} }=\frac{4 }{12 }*\frac{x }{ x^{-1/3} }*\frac{y^{-2} }{ y^{-5} }

Since \frac{x^{a} }{x^{b}} =x^{a-b},
then:
*** \frac{x}{ x^{-1/3} }= x^{1-(-1/3)} = x^{3/3+1/3} = x^{4/3}
*** \frac{y^{-2} }{ y^{-5} }=  y^{-2-(-5)} = y^{-2+5} = y^{3}
______
\frac{4 }{12 }*\frac{x }{ x^{-1/3} }*\frac{y^{-2} }{ y^{-5} }= \frac{1*4}{3*4}* x^{4/3}*y^{3}= \frac{1}{3} * x^{4/3}*y^{3}= \frac{x^{4/3}y^{3}}{3}

QUICK WHATS THIS ANSWER?!?
Mars2501 [29]

Answer:

C. -x-6>-3.5

Step-by-step explanation:

One is asked to find which inequality has (x=-3) in its solution set. Remember that an inequality is another way to represent a set of solutions. In essence, it states that all numbers less than; less than or equal to; greater than; or greater than or equal to, are a part of the solution. One simplifies an inequality in a similar manner to how one simplifies an equation, by using inverse operations and simplification. Just note that when multiplying or dividing the inequality by a negative number, one has to flip the inequality sign to ensure the expression remains true.

Simplify each of the inequalities, then evaluate to see which one has (x=-3) as a part of its solution set.

A. -x -6

-x

x>-2.5

B. -x-6>3.5

-x>9.5

x

C. -x-6>-3.5

-x>2.5

x

D. x-6>-3.5

x>2.5

As can be seen, option (C -x-6>-3.5) is the only one that fits this requirement. Since option (C) simplifies down to (x) or in words, (x) is less than (-2.5). This option is the only one that fits the solution since (-3) is less than (-2.5).

Animal y=5.4x+34<br> person y=12x+8.5 y is weight x is years. when is the weight the same
I am Lyosha [343]

Answer:

Step-by-step explanation:

Animal                 Person

y = 5.4x + 34       y = 12x + 8.5; where y - weight, x - years

looking for when weight (y) is the same, so we need

animal weight (y) = person weight (y)

            5.4x + 34 = 12x + 8.5

        <u>   -5.4x           -5.4x</u>

                      34 = 6.6x + 8.5

                  <u>  -8.5             -8.5</u>

                   25.5  = 6.6x     divide both sides by 6.6

                         x = 3.86  years

not sure if you need your answer in decimal or what, but you can adjust accordingly.
