kompoz [17]

Answer:

\frac{-27}{x^{15}}=-\frac{27}{x^{15}}

Step-by-step explanation:

<em>If you just want to simplify -27/x^15, it is not very difficult. Here is the simple way.</em>

<em />

Given the expression

\frac{-27}{x^{15}}

solving

\frac{-27}{x^{15}}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}

=-\frac{27}{x^{15}}

Therefore,

\frac{-27}{x^{15}}=-\frac{27}{x^{15}}

Number 13 explain......
Marat540 [252]
The slope is 2 and the equation of the line is y = mx+b with m =2

Then the equation becomes: y = 2x+b. How to calculate b?
Since this line passes through the point (-3 , 4), we replace x with -3 and y=4

4= 2.(-3) + b 
4 = - 6 + b
and b= 10. The final equation is : y = 2x + 10 (answer a)

Can someone help me with this? Preferably with an explanation on how to actually figure this out. Thank you!
zhannawk [14.2K]

Answer:

2^-4, 1/16, (1/2)^4

There is a rule with exponents, if you are dividing two exponents you subtract the first exponent from the other to simplify it, also meaning it's equivalent.

So in this case 5-9 = 2^-4

The others were found by evaluation.
