You should plot an arrow, with open-circle, starting in the number 9. See the image attached.

<h3>Inequality </h3>

It is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use of follow symbols: $\leq$ (less than or equal to), $\geq$ (greater than or equal to), < (less than) and > (greater than).

The solutions for inequalities can be given by: graph in a number line or numbers. Your question requests a graph solution, but it is necessary to find a number solution to plot it in the graph.

Step 1 - Find x

$x+3$

Step 2 - Plot the solution

See the attached image. For graph solution, you should use the open-circle because your number solution use the symbol less than (<).

What is 25 percent of 148

valentina_108 [34]

Answer: 37

Step-by-step explanation: To find 25% of 148, first write 25% as a decimal by moving the decimal point two places to the left to get .25 which is the decimal equivalent to 25%.

Next, the word "of" means multiply so we will need to multiply.

(.25) (148) = 37

Therefore, 37 is 25% of 148.

If you can multiply Ax B, then which of the following statements is true about

HACTEHA [7]

To multiply B and A, the number of columns of B must matc the number of rows of A.

<h3>When we can multiply two matrices?</h3>

When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.

Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).

To multiply BxA:

Then, a row on matrix B must have the same number of elements than a column in row A.

Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.
