  • 12x⁹y⁵/2x²y⁻²
  • => 6x⁹y⁵/x²y⁻²
  • => 6x⁹⁻²y⁵⁺²
  • => 6x⁷y⁷

<u>Question 14:</u>

  • (5y⁻³/x⁻²)²
  • => (25y⁻⁶/x⁻⁴)
  • => 25x⁴y⁻⁶

<u>Answer</u>:

13. 6x^7 y^7   ||     14. \frac{25x^4}{y^6}

<u>explanation</u>:

13.

\frac{12x^9 y^5}{2x^2 y^-2}

6x^{9-2} y^{5--2}

6x^7 y^7

14.

(\frac{5y^{-3} }{x^{-2} } )^{2}

(\frac{5y^{-3} }{x^{-2} } )(\frac{5y^{-3} }{x^{-2} } )

\frac{\frac{25}{y^6}}{\left(x^{-2}\right)^2}

\frac{\frac{25}{y^{-6} }}{\left(x^{-4}\right)}

\frac{25x^4}{y^6}

Please Help! What is the distance between points (2, 8) and (7, 5)? Round to the nearest tenth of a unit.
zavuch27 [327]
Distance formula is like pythagoren ahtoerem
D=\sqrt{(7-2)^{2}+(5-8)^{2}}
the distance between oints (x1,y1) and (x2,y2) is
D=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}
(2,8) and (7,5)
D=\sqrt{(7-2)^{2}+(5-8)^{2}}
D=\sqrt{(5)^{2}+(-3)^{2}}
D=\sqrt{25+9}
D=\sqrt{34}
apxos
D=5.8309....

X plus 9 divided by 7 equals 3
zavuch27 [327]

Answer- <em>X=12</em>

Step-by-step explanation:

X + 9/7 = 3 is our equation

Then we are going to do the opposite of dividing 7 from 9 which is multiplying  7 from 9. (on both sides)

It will leave us with - X + 9 = 21

Then we will do the opposite of adding 9 to X which is subtracting 9 from X. (also on both sides) ( whenever you do any adding or subtracting or multiplying or dividing on one side you have to do it on the other for the equation to be true)

Now it will leave us with X = 12

And that's our answer! :>

What number is 15% of 80?<br> use percent proportions
vova2212 [387]
!5% is equivalent to 15 parts over the whole 100 part. It is written in proportions as 15/100. 

Similarly, you need to find how many parts in 80 are equivalent to 15%or 15/100. So, just equate both equation with x as an unknown.

x/80 = 15/100
x = (15/100)*80
x = 12

Thus, the 15% of 80 is 12.
