Matrix operations includes the addition, multiplication and subtraction of matrices

The correct option for the matrix that can be used to represent B is option D)

[tex]D) = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The reason the above option is correct is as follows:

From the graph, we have that the coordinates of the preimage are;

(-6, 5), (-3, 9), and (6, 5)

The coordinates of the preimage in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

The coordinates of the image are;

(-6, -5), (-3, -9), and (6, -5)

The coordinates of the image in matrix form is given as follows;

[tex]\left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

The above image matrix can be obtained from the primage matrix as follows:

[tex]\left[\begin{array}{rrr}1&0\\0&-1\end{array}\right]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right] = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Which is of the form AB = C

Where;

[tex]A = \left[\begin{array}{rrr}1&0\\0&-1\end{array}\right][/tex]

[tex]B = \left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex]

[tex]C = \left[\begin{array}{rrr}6&-3&-6\\-5&-9&-5\end{array}\right][/tex]

Therefore, the matrix that could represent B is [tex]\left[\begin{array}{rrr}6&-3&-6\\5&9&5\end{array}\right][/tex] which is option D)

Answer:

y = -3x - 4

Step-by-step explanation:

-3x - y = 4

~Add 3x to both sides

-y = 4 + 3x

~Divide -1 to everything

y = -4 - 3x

~Reorder

y = -3x - 4

Answer:

They're parallel lines .

Step-by-step explanation:

But they are perpendicular to the lines they meet with. i.e; width lines are parallel to each other. But width lines are perpendicular to length lines.

[tex]{ \sf{}}[/tex]

Answer:

Parallel lines

Step-by-step explanation:

It wouldn't be perpendicular lines because a perpendicular line is when two lines come together to make a perfect corner, or 90 degree angle. It wouldn't be neither because parallel lines is when they face each other and if they were to go on forever they would never touch because they go straight. That may sound confusing but and example would be like the opposite lines on a square, how they're perfectly straight and opposite each other. The answer is parallel lines. Hope this helps! Good luck.

Answer:

x= (5X+3) DEGREES = 90 degrees (right angle)

5x=90 degrees - 3 degrees =87 degrees

5x÷5 =87 degrees ÷ 5

x=17.4 degrees

we now know our angles x = 17.4 degrees so we can know substitute into the give formula

wxz=5 (17.4)+ 3

wxz =90 degrees

zxy=we know the size of x

zxy=

Answer:

The perimeter of the figure is 14.71 ft

Step-by-step explanation:

The outer perimeter of the figure is the sum of the boundary dimensions.

The missing outer dimension is the length of the arc or half circumference.

Length of arc formula/half circumference = 1/2 πr = 1/2 x 3.14 x 3 ft = 4.71 ft

The other dimensions are 5ft and 5ft.

Therefore, the outer perimeter of the figure is:

4.71 ft + 5 ft + 5 ft = 14.71 ft
