What is the solution to the system of linear equations represented by the matrix equations below. Please help!!!!!
The system of equations has infinite solutions.
Option D is correct.
What is matrix multiplication?Matrix multiplication is a binary operation whose output is also a matrix when two matrices are multiplied.
To multiply one matrix with another, we need to check first, if the number of columns of the first matrix is equal to the number of rows of the second matrix. Now multiply each element of the column of the first matrix with each element of rows of the second matrix and add them all.
Given
Matrix equations
[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}6\\3\end{array}\right][/tex]
L.H.S:
Using Matrix multiplication
[tex]\left[\begin{array}{ccc}2&4\\1&2\end{array}\right] \left[\begin{array}{ccc}x\\y\end{array}\right] = \left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right][/tex]
R.H.S:
[tex]\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}2x+4y\\x+2y\end{array}\right]=\left[\begin{array}{ccc}6\\3\end{array}\right][/tex]
Writing equation from above matrix
2x + 4y = 6
x + 2y = 3
or
2x + 4y = 6
2x + 4y = 6
Because there are two unknown number, but the two equations are consistent.
So, the system of equations has infinite solutions.
Option D is correct.

Please help this is late work for geometry and I keep getting this awnser wrong
Answer:
w = 12°
Step-by-step explanation:
Angle J = Angle H
Angle K = Angle I
So lets find the sum of the entirety of angles
360° = 2w + 34° + 2w + 34° + 4w + 74° + 4w + 74°
360° = 12w + 68° + 148°
360° = 12w + 216°
Subtract 216° from both sides
360° - 216° = 12w + 216° - 216°
144° = 12w
Divide both sides by 12
144°/12 = 12w/12
12 = w
w = 12°

-Chetan K
Answer:
58°Step-by-step explanation:
Consider that adjacent angles are supplementary in any parallelogram (including rhombus).
m∠J + m∠K = 180°(2w + 34) + (4w + 74) = 180Solve for w:
6w + 108 = 1806w = 72w = 12Find the value of ∠J:
m∠J = 2w + 34 = 2(12) + 34 = 58Henry is thinking of a number that is less than 17. What numbers make the statement true q<17 true? Solve the problem any way you choose

The missing values of the similar triangles is x = 20/3 and y = 4.5
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ΔABC
Let the second triangle be ΔXYZ
Now , the corresponding sides are
15 / 10 = y / 3
Multiply by 3 on both sides , we get
y = 45 / 10
y = 4.5
Now , for the similar triangles , corresponding sides of similar triangles are in the same ratio
And , 2 / 3 = x / 10
Multiply by 10 on both sides , we get
x = 20/3
Hence , the similar triangles are solved

Glenn has a garden that is shaped like a rectangle.
The perimeter of his garden is 7012 feet.
The length of the garden is 2434 feet.
What is the width of the garden?
21 ft o 11ft o 10 ½ ft o 45 ¾ ft
Answer:
Solution given:
The length of the garden[l] = 2434 feet.
breadth or width [b]=b
perimeter of his garden = 7012 feet.
2[l+b]=7012ft
2434+b=7012/2
b=3506-2434
b=1072
So the width of the garden is 1072ft.

what is a square root?
Answer:
A number multiplied by its self for ex 7 x 7 = 49 square root of 49 is 7
Answer:
A square root of a number is a value that, when multiplied by itself, gives the number. 6 · 6 = 36, so a square root of 36 is 6. You are probably curious why I said a square root and not the square root. - 6 · - 6 = 36. - 6 is a square root of 36. The symbol is √ which always means the positive square root.
√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5
√36 = 6
√49 = 7
√64 = 8
√81 = 9
√100 = 10
