1) When you have an exponent being raised to an exponent, you multiply them. 2*3 is 6, so you have x^6, which would make C your answer.
2) You reduce them by subtracting the top ones from the bottom ones, so it becomes x^2*z. The y's cancel out, 6-4 is 2 and 9-8 is 1. Your answer is C again.
3) As you did in one, simply multiply out the top first. The top them becomes 9x^12*y^18. Subtract the bottom exponents to get 9x^6y^9/3, which then becomes 3x^6*y^9, which is D.
4) When you have a square root over a square root, you can put the numbers inside like this: . 81 over 27 is equal to 3, so you have sqrt3 as your answer - A.
5) You have sqrt2*2*sqrt3. You can put 2*3 under the square root together, and they multiply to 6, so you have 2sqrt6 - D.
9/27 is equivalent to 2/27
Answer:
9 months.
Step-by-step explanation:
Well we subtract the one time fee of $150 from $420
420-150=270
Now we need to divide $270 by $30, the price she pays every month.
270÷30=9
She has had the service for 9 months.
The point of ntersection is 2, 1 because 3-1 is 2 and 2 - 1 is 1 combine them 2, 1
Question:
Solve for x: . Fill in both values for x below. Write the greater value for x in the first column.
Answer:
and are the values for x.
Explanation:
The equation is
Subtracting both sides by 7,
Dividing both sides by 12,
Now, we shall write the equation by removing modulus by adding plus and minus on the other side of the equation.
or
Solving the equation , we get,
or
Thus, the solutions are and
