The simplified form of the expression is $x^{-45} y^{-42}$

<h3>Simplifying an expression</h3>

From the question, we are to simplify the given expression

The given expression is

$\frac{x^{8}y^{-26} }{x^{14}y^{-5} } \times x^{-39} y^{-21}$

The expression can be simplified as shown below

$\frac{x^{8}y^{-26} }{x^{14}y^{-5} } \times x^{-39} y^{-21}$

$\frac{x^{8} \times x^{-39} \times y^{-26} \times y^{-21} }{x^{14} \times y^{-5} }$

$\frac{x^{8+-39} \times y^{-26+-21} }{x^{14} \times y^{-5} }$

$\frac{x^{8-39} \times y^{-26-21} }{x^{14} \times y^{-5} }$

$\frac{x^{-31} \times y^{-47} }{x^{14} \times y^{-5} }$

Then,

$\frac{x^{-31} }{x^{14} } \times \frac{ y^{-47} }{ y^{-5} }$

$x^{-31-14} \times y^{-47--5}$

$x^{-31-14} \times y^{-47+5}$

$x^{-45} \times y^{-42}$

$x^{-45} y^{-42}$

Hence, the simplified form of the expression is $x^{-45} y^{-42}$

Which is the slope of a line that is perpendicular to the line represented by the equation x-y = 8

Marat540 [252]

Answer:

-1

Step-by-step explanation: from the equation, x-y=8, make y the subject of the formulae , this gives - y= -x +8

divide all through by (-) sign, this gives y= x - 8

from the last equation above, the slope is the coefficient of x which is 1. since it is perpendicula, the answer is -1

by co efficient, we mean the number multiplying the unknown

What seems to cause an Input value to be circled?

RideAnS [48]

Answer:

For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.

Step-by-step explanation:

For example, x > 2 would have an open circle and you are NOT including the 2 that is inputted.

For x $\leq$ 6, it would have a closed circle and you ARE including the 6 that is inputted.
