Answer:
Dividing exponents you subtract.
3^8/3^5 = 3^3
3^3
Multiplying exponents when an exponent is raised to another.
(3^3)^3 = <u>3^9</u>

Apparently this makes no sense according to comments, if you want a more indepth look into exponents search "The properties of exponents".
Answer:
3y= -2x-6
Step-by-step explanation:
The two points on the line are (-3,0) and (0,-2)
so you first get the gradient;
gradient= <u>change in y</u>
change in x
= <u>-2-0</u>
0-(-3)
=<u> -2</u>
3
so the answer above is the gradient
then pick one point that you used to get the gradient with, so as for me I'll pick (-3,0) and then a general point which is always (x, y)
since you have the gradient you can easily get the equation by doing this
<u>y-0</u><u>. </u><u> </u> = <u>-2</u>
x-(-3). 3
then crossmultiply to get the equation of the line
3y= -2(x+3)
3y= -2x-6
Answer:
Also read the problem carefully to determine if there are any other changes in the inverse ... Example 1 – If x varies inverse as y, and x = 7 when y = 3, find y when x = 9. ... If the volume is 32 cubic centimeters at a pressure of 8 pounds, find the ...

The answer is <span>c. 2.34 g.
Some rules of rounding are:
</span>1. If the number that you rounding is followed by 0, 1, 2, 3, and 4, the number will be rounded down (eg. 0.22 is rounded to 0.2). <span>
2. If the number that you rounding is followed by 6, 7, 8, and 9, the number will be rounded up (eg. 0.27 is rounded to 0.3).
</span>3. If the number that you rounding is even and followed by 5, the number will remain even (eg. 0.25 is rounded to 0.2).
4. If the number that you rounding is odd and followed by 5, the number will be rounded up to an even number (eg. 0.15 is rounded to 0.2).
So, let's start rounding:
2.33501 is rounded to 2.3350 (rule 1).
2.3350 is rounded to 2.335 (rule 1).
2.335 is rounded to 2.34 (rule 4).
Thus 2.33501 is rounded to 2.34.
