What would you do to solve the equation below?
solmaris [256]

Answer:

add 3 to both sides of the equal sign

Step-by-step explanation:

to solve the equation you would have to add three

that is because you have to do inverse operations

and you would add because the opposite of subtracting is adding

so solving it would look like this

x - 3 = 12

  +3   +3

x = 15

this is how you check the answer:

15 - 3 = 12

    +3   +3

For this exercise assume that all matrices are ntimesn. Each part of this exercise is an implication of the form​ "If "statement
inna [77]

Answer:

C. True; by the Invertible Matrix Theorem if the equation Ax=0 has only the trivial solution, then the matrix is invertible. Thus, A must also be row equivalent to the n x n identity matrix.

Step-by-step explanation:

The Invertible matrix Theorem is a Theorem which gives a list of equivalent conditions for an n X n matrix to have an inverse. For the sake of this question, we would look at only the conditions needed to answer the question.

  • There is an n×n matrix C such that CA=I_n.
  • There is an n×n matrix D such that AD=I_n.
  • The equation Ax=0 has only the trivial solution x=0.
  • A is row-equivalent to the n×n identity matrix I_n.
  • For each column vector b in R^n, the equation Ax=b has a unique solution.
  • The columns of A span R^n.

Therefore the statement:

If there is an n X n matrix D such that AD=​I, then there is also an n X n matrix C such that CA = I is true by the conditions for invertibility of matrix:

  • The equation Ax=0 has only the trivial solution x=0.
  • A is row-equivalent to the n×n identity matrix I_n.

The correct option is C.

There are 60 marbles in a bowl. 1/3 of them is red, 1/4 is blue and the rest has now colour. How many marbles have no colour?
Gwar [14]

Answer:25

Step-by-step explanation: since 1/3 of the marbles is red, we’ll divide 60 by 3, which equals 20. Since 1/4th are blue, we’ll do 60/4=15. 20+15=35. We’re finding the amount with no color, so subtract 35 from 60. We have 25
