Answer from: notcollin2416

$\frac{4}{ {x}^{14} {y}^{8} }$

Step-by-step explanation:

Follow the steps below.

$( \frac{( {2}^{ - 3})( {x}^{ - 3})( {y}^{2} }{( {4}^{ - 2})( {x}^{4} )( {y}^{6} } {)}^{2}$

Multiply exponents by the exponent outside of the perentheses (2).

$( \frac{( {2}^{ - 6} )( {x}^{ - 6})( {y}^{4} ) }{( {4}^{ - 4})( {x}^{8} )( {y}^{12}) } )$

Subtract the variables' and non-variables' exponents from each other and divide the non-variables.

$( { \frac{1}{2} }^{ - 2} ) ( {x}^{ - 14} )( {y}^{ - 8} )$

Solve for the non-variable.

$(4)( {x}^{ - 14} )( {y}^{ - 8} )$

Make the variables the denominator to remove the negative exponents and make them positive.

$\frac{4}{ {x}^{14} {y}^{ 8} }$

There is your answer

Answer from: Quest

the system of inequity is

$y\leq -x+4$

$3y> x$

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

the solid line passing through the points (0,4) and (4,0).

$y-4=\frac{0-4}{4-0}(x-0)$

$y=-x+4$

the related equation of solid line is $y=-x+4$ .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

$y-0=\frac{0-1}{3-0}(x-0)$

$3y=x$

the related equation of dashed line is $3y=x$

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

$1=-0+4$

$1=4$

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be $\leq$ . the required inequality is

$y\leq -x+4$

similarly, check the second related equation.

$3(1)=0$

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

$3y> x$

15 points write a system of inequalities to represent the shaded portion of the graph

Answer from: Quest

a 4/6 = 9/12 not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional. if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional

b 2/3 = 12/18

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
