<u><em>Answer:</em></u>

<u><em>D. 51</em></u>

Explanation:

This question's it's about the order of operations. P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right.

First, do exponents.

6^2=6*6=36

Then add left to right.

36+15=51

\boxed{=51}

Hope this helps!

Thanks!

Have a great day!

The ratio of two numbers is 9 to 8, and their sum is 187. What are the numbers?
m_a_m_a [10]
<h3>Answer:  99 and 88</h3>

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

Explanation:

The ratio of the two numbers is 9 to 8, which we can write as shorthand into 9:8

Multiplying both parts by x gets us the ratio 9x:8x where x is nonzero.

The numbers 9x and 8x add up to 187, so,

9x+8x = 187

17x = 187

x = 187/17

x = 11

Which then means

  • 9x = 9*11 = 99
  • 8x = 8*11 = 88

are the two numbers. Note how 9x+8x = 99+88 = 187 to help confirm the answers. Furthermore, note how 99:88 reduces to 9:8 after dividing both parts by the GCF 11.

Change 3Y - 2X = -6 to the slope-intercept form of the equation of a line.
k0ka [10]

Answer:

y = 2/3x -2

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

3y -2x = -6

Solve for y

Add 2x to each side

3y = 2x-6

Divide by 3

3y/3 = 2x/3 -6/3

y = 2/3x -2

Which answer choice shows that the commutative property does not hold for matrix multiplication?
Bess [88]

Given:

The matrix statements in the options.

To find:

The answer choice that show the commutative property does not hold for matrix multiplication.

Solution:

We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then

AB\neq BA

Let us assume,

A=\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\text{ and }B=\begin{bmatrix}1&3\\8&5\end{bmatrix}

According to the above property of the matrix, we get

\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\begin{bmatrix}1&3\\8&5\end{bmatrix}\neq \begin{bmatrix}1&3\\8&5\end{bmatrix}\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}

Therefore, the correct option is B.
