First, you just need to disregard the greater than sign because these types of equation is solved the same way as those with equals (=) sign in the middle. So when y=6,
First you need to substitute y=6 to the y in 3y

3(6)>2x

By multiplying,

18>2x

By dividing both sides of the equation by 2

18/2 > 2x/2

9>x

However if you want to transpose x to the left side of the equation, you also need to reverse the sign to <

Which means

X<9

If y=6 them we will have

3*6>2x
18>2x

x must be smaller than 9, because
18=2*9 => 18=18, and we doesn't respect the rule

now that we know that x<9 we have other 2 cases...
1. x is a natural number x can take values from the interval [0, 8]
2. x is a rational number, so it can take values from the interval [8, - infinite)

Answer:

$= {x}^{ - 11} {y}^{ - 11} {z}^{ - 10}$

Step-by-step explanation:

$= \frac{ {x}^{ - 9} {y}^{ - 5} {z}^{ - 7} }{ {x}^{2} {y}^{6} {z}^{3} } \\ = {x}^{ - 9 - 2} {y}^{ - 5 - 6} {z}^{ - 7 - 3} \\ = {x}^{ - 11} {y}^{ - 11} {z}^{ - 10}$

About how far apart do aesha and Josh live

Vesnalui [34]

Answer:

D. about 8.5 mi

Step-by-step explanation:

To go from Aesha to Josh, you go 6 units right and 6 units up.

Each unit is a mile, so you go 6 miles right and 6 miles up.

Think of each 6 mile distance as a leg of a right triangle, and the direct distance from one place to the other as the hypotenuse of the right triangle. Use the Pythagorean theorem to find the length of the hypotenuse.

a^2 + b^2 = c^2

The 6-mile legs are a and b. c is the hypotenuse.

(6 mi)^2 + (6 mi)^2 = c^2

c^2 = 36 mi^2 + 36 mi^2

c^2 = 72 mi^2

c = sqrt(72) mi

c = sqrt(36 * 2) mi

c = 6sqrt(2) mi

c = 6(1.4142) mi

c = 8.5 mi
