Answer:

$x^{15}$

Step-by-step explanation:

Distribute the ^3 on top

(27 $x^{6}$ $y^{-9}$ )

distribute the ^ -9 on bottom, only to what is in the parenthesis

(27 $x^{-9}$ $y^{-9}$ )

the 27's cross out, the $y^{-9}$ 's cross out

$x^{6}$ / $x^{-9}$ is left

move the $x^{-9}$ to the top of fraction to change its sign

$x^{6}$ · $x^{9}$ = $x^{15}$

Travka [436]

Answer: $RM 31631$

Step-by-step explanation:

We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:

$RM 57000(\frac{8}{9})^{n}$

Where $RM 57000$ is the price of the car when it was bought new, and $n=5$ is the number of years the car was used.

Solving the formula with the given data:

$RM 57000(\frac{8}{9})^{5}=RM 31630.95$ This is the value of the car according to the formula.

However, this value can be approximated to:

$RM 31631$

Find the slope and y-intercept of the line x+3y=3...

katovenus [111]

So first put this in slope intercept form, y=mx+b. subtract x from both sides so now you have 3y=-x+3 and to get y by itself divide both sides by 3 so now you have y=(-x/3) +1 or y=-1/3(x)+1 the slope is m and the y-intercept is b so the slope is -1/3 and the y-intercept is 1
