Evaluate UV if possible.
Mnenie [13.5K]

Answer: B

Step-by-step explanation:

Multiply U and V:

\begin{pmatrix}-9&1&0\\ \:4&0&2\\ \:0&1&5\end{pmatrix}\begin{pmatrix}2\\ \:-2\\ \:1\end{pmatrix}

\mathrm{Multiply \ the \ rows \ of \ the \ first \ matrix \ by \ the \ columns  \ of \ the \ second \ matrix:}

\begin{aligned}&\left(\begin{array}{ccc}-9 & 1 & 0\end{array}\right)\left(\begin{array}{c}2 \\-2 \\1\end{array}\right)=(-9) \cdot 2+1 \cdot(-2)+0 \cdot 1 \\&\left(\begin{array}{ccc}4 & 0 & 2\end{array}\right)\left(\begin{array}{c}2 \\-2 \\1\end{array}\right)=4 \cdot 2+0 \cdot(-2)+2 \cdot 1 \\&\left(\begin{array}{lll}0 & 1 & 5\end{array}\right)\left(\begin{array}{c}2 \\-2 \\1\end{array}\right)=0 \cdot 2+1 \cdot(-2)+5 \cdot 1\end{aligned}

=\begin{pmatrix}\left(-9\right)\cdot \:2+1\cdot \left(-2\right)+0\cdot \:1\\ 4\cdot \:2+0\cdot \left(-2\right)+2\cdot \:1\\ 0\cdot \:2+1\cdot \left(-2\right)+5\cdot \:1\end{pmatrix}

\mathrm{Simplify\:each\:part:}

=\begin{pmatrix}-20\\ 10\\ 3\end{pmatrix}

Therefore, the correct answer is B

Type the greater integer -3 or 1 Its 1 right?
PtichkaEL [24]
1 Is definitely bigger than -3, because 1 - 4 = -3.

Think of it like a line:

-100.............10......0........10............100

What measurement is equivalent to 6 kilograms?
Anna007 [38]

Answer:

  6000 g

Step-by-step explanation:

In the metric system, 6 kg = 6000 g. (The prefix kilo- means 1000.)

__

In other units of measurement, 6 kg ≈ 13.2277357311 pounds. This is not an exact conversion.

What is the equation of the line
olga2289 [7]

Answer:

It's the first choice y = (-5/2)x - 1.

Step-by-step explanation:

First find the slope of the line  5x + 2y = 12 by converting to slope-intercept form.

5x + 2y = 12

2y = -5x + 12

y = (-5/2)x + 6   so the slope is (-5/2).

The line we require had also a slope of -5/2 because it is parallel to the first line and it also passes through the point (-2, 4). So:

y - 4 = (-5/2)(x - -2)      (the point-slope form)

y - 4 = (-5/2)(x + 2)

y = (-5/2)x - 5 + 4

y = (-5/2)x - 1  (answer)
