Consider a homogeneous machine of four linear equations in five unknowns are all multiples of 1 non-0 solution. Objective is to give an explanation for the gadget have an answer for each viable preference of constants on the proper facets of the equations.

Yes, it's miles true.

Consider the machine as Ax = 0. in which A is 4x5 matrix.

From given dim Nul A=1. Since, the rank theorem states that

The dimensions of the column space and the row space of a mxn matrix A are equal. This not unusual size, the rank of matrix A, additionally equals the number of pivot positions in A and satisfies the equation

rank A+ dim NulA = n

dim NulA =n- rank A

Rank A = 5 - dim Nul A

Rank A = 4

Thus, the measurement of dim Col A = rank A = five

And since Col A is a subspace of R^4, Col A = R^4.

So, every vector b in R^4 also in Col A, and Ax = b, has an answer for all b. Hence, the structures have an answer for every viable preference of constants on the right aspects of the equations.

What is 2/3 divied by 3 in fraction form
Ede4ka [16]
The answer that you are looking for 1/5, you basically 2/3 in decimal form is 0.6. Then you divide by 3 to get 0.2. Then the way I did this was by first doing 2 over 10 (2/10), then reduced it to 1/5 (1 over 5). 

*This was the way I did it, you don't have to do it this way. Find a way that is easiest for you to answer problems like this in the future.

asappp please someone help i’ll give brainliest. i’m trying to find x, and by what form like ASA, etc
Alex777 [14]

Answer:

  • x = 40.375

Step-by-step explanation:

<u>∠A≅∠E, ∠B≅∠F and ∠C is common and congruent to itself, therefore</u>

  • ΔABC  ~ ΔEFC by AA similarity

<u>Ratio of corresponding sides is same. Get the equation below and solve for x:</u>

  • EC/AC = CF/CB
  • x/17 = (16+22)/16
  • x/17 = 38/16
  • x/17 = 19/8
  • x = 17*19/8
  • x = 40.375

The parallelograms below are similar.
Alexxx [7]

9514 1404 393

Answer:

  AB = 4

  ∠E = 30°

Step-by-step explanation:

Side AD is 4 times the length of corresponding side EH, so we expect side AB to be 4 times the length of side EF.

  AB = 4·EF = 4·1

  AB = 4

__

Angle E will have the same measure as corresponding angle A.

  angle E = 30°

Answer:

CA = 32

Step-by-step explanation:

By intersecting chords theorem:

12(4x + 1) = 14(3 + 3x) \\  \\ 48x + 12 = 42 + 42x \\  \\ 48x - 42x = 42 - 12 \\  \\ 6x = 30 \\  \\ x =  \frac{30}{6}  \\  \\ x = 5

CA = 14 + ( 3 + 3x)

CA = 14 + ( 3 + 3*5)

CA = 14 + ( 3 + 15)

CA = 14 + 18

CA = 32
