Construct an augmented matrix for this linear system:

x − y − 4z = 5
2x + 2z = 0
4x + y + z = 3

Step-by-step explanation:

In an augmented matrix, each row represents one equation in the system and each column represents coefficients (including signs) of variables or the constant terms.

So, the first row is

the second row is

and the third row is

Hence, an augmented matrix for this linear system is

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
