Answer:

A. 9y - x = 2

Step-by-step explanation:

9y - x = 2. First to get x on the other side we add x to both sides gettings us this. 9y -x + x = 2 + x or just 9y = x + 2. Then divide by 9 to get y alone. We then get y = x/9 + 2/9. The rate of change is clearly not y = 9x here, it's y = x/9 or 1/9x.

3.8 times 10 to the power of -8

Yuliya22 [10]

Answer:

1/38^8

Step-by-step explanation:

3.8 times 10 is 38

so it would be 38 to the power of -8 ( 38^-8 )

then you simplify

you have to rewrite the negative power

( you can't have negative power as numerator )

$\frac{38^{-8} }{1}$

so you put it a part of the denominator

which switches the sign

$\frac{1}{38^{8} }$

hope this helps
