Answer:

below.

Step-by-step explanation:

The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.

Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.

[ -8 2 2] { 3 }

[ 0 ]

[ -3]

= -8*3 + 2*0 + 2 * -3 = [-30] <-------- Answer.

Note a 1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.

Express as a fraction 2 3/7 pounds to 2 6/7 pounds

dmitriy555 [2]

$\bf \begin{cases}
2\frac{3}{7}\implies \cfrac{2\cdot 7+3}{7}\implies &\cfrac{17}{7}\\
2\frac{6}{7}\implies \cfrac{2\cdot 7+6}{7}\implies &\cfrac{20}{7}
\end{cases}
\\ \quad \\
\textit{a to b}\implies a:b\implies \frac{a}{b}\qquad thus
\\ \quad \\
2\frac{3}{7}\ to\ 2\frac{6}{7}\implies 2\frac{3}{7}:2\frac{6}{7}\implies 
\cfrac{2\frac{3}{7}}{2\frac{6}{7}}
\implies 
\cfrac{\frac{17}{7}}{\frac{20}{7}}
$
$\bf recall\implies \cfrac{\frac{a}{b}}{\frac{c}{{{ d}}}}\implies \cfrac{a}{b}\cdot \cfrac{{{ d}}}{c}\qquad thus
\\ \quad \\\\ \quad \\
\cfrac{17}{7}\cdot \cfrac{7}{20}\implies \cfrac{17\cdot 7}{7\cdot 20}\implies \cfrac{\boxed{?}}{\boxed{?}}$

If a system of two inequalities has a solution, then their two half planes intersect , true or false ?

Nana76 [90]

Answer: The answer is true.

Step-by-step explanation: The given statement is

'If a system of two inequalities has a solution, then their two half planes intersect'.

We are to check whether the statement is true or false.

Let a system of two inequalities be

$x+y\geq 3,\\\\2x+5y\leq 10.$

These inequalities has a solution, for example, x = 2, y = 1.

Plotting these inequalities on a graph paper (please see the attached graph), we see that the two half planes intersect, which is represented by the double shaded region in the graph.

Thus, the given statement is TRUE.
