WHAT IS 6 TO THE THIRD POWER +5 (8+ ONE FIFTH

Mathematics
1 answer:
denis23 [38]3 years ago
7 0
The answer would be 353.6

6 to the third power (or 6 times 6 times 6) would come out to be 216.

You'd then add 216 and 5 to get 221.

The next step would be to add 8 to 1/5 and get 1.6.

The final step would be to multiply 1.6 and 221 which would give you 353.6.

The answer is 2k^2 - 7k - 4 because 2k x k is 2k^2 and 2k x (-4) is -8k and 1 x k is k and 1 x (-4) is -4. So then you would get 2k^2 - 8k + k - 4 which simplifies to 2k^2 - 7k - 4 which is your answer.

Which system of equations is represented by the matrix below? 1 5 11 4 -6-3 A. y + 5x = 11 4y - 6x = -3 B. X+ 5y = 11 4x - 6y =
Vitek1552 [10]

Answer: Choice B

x+5y = 11\\4x-6y = -3

=====================================

Explanation:

The given matrix is

\left[\begin{array}{cc|c}1&5&11\\4&-6&-3\end{array}\right]

The numbers to the right of the vertical bar represent the values on the right hand side of each equation in the final answer.

The numbers to the left of the bar represent the x and y coefficients of the equations. The first number of any given row is the x coefficient. The second number is the y coefficient.

For instance, the first row has \begin{array}{cc}1&5\end{array} to indicate the x coefficient is 1, and the y coefficient is 5. We end up with 1x+5y or simply x+5y. Putting everything together, the first equation would be x+5y = 11

Through similar steps, the second equation is  4x-6y = -3

What is -3/4 + 3/8? Thanks.
AURORKA [14]

Answer:

-  \frac{3}{8}

Step-by-step explanation:

First, we change both denominators to the LCM (lowest common multiple) which is 8.

-  \frac{3}{4}  +  \frac{3}{8}  =  -  \frac{6}{8}  +  \frac{3}{8}

Since the denominators are the same, we can add the numerators.

\frac{ - 6 + 3}{8}

\frac{ - 3}{8}

or it can be written as

-  \frac{3}{8}
