y = 12/13x - 2/13, characters
With an expression like this, you have to raise all the terms to the 3rd power. So the 5 will become

,

will become

, the 4 will become

and finally, the

becomes

. If you place all of these together in the same fraction, the new answer equivalent to the initial expression is
To find the length of the arc given the central angle, multiply (the fraction of the angle of the full circle, 360°, that the central angle, 120°, makes up)*(the total circumference of the circle). You're basically finding the fraction of the circumference that is covered by the central angle, if that makes any sense.
So the central angle makes up

the entire circle. You are given that the circumference of the circle is 18. Multiply the fraction of the full circle that the central angle makes up (

) by the circumference of the circle:
The length of your arc is 6.
Let me know if you're confused b/c my explanation isn't the greatest :) I'll try to explain it better if you don't understand.
Answer:
Step-by-step explanation:
Coordinates ( x, y ) from "red area" satisfy all three inequality.
Answer:

Step-by-step explanation:
When you multiply two exponents together with the same base, the exponents get added
Here the base is the same ie b
So 
The constants multiply in the usual sense so 7(-9) = -63
Answer is
