Use an augmented matrix to solve the system. what is the value of x and y? x+y=5 3x-y=-1 a. (1,4) b. (1,5) c. (3,-1) d. (5,-1) when converting a linear equation into an augmented matrix, which equation form is needed? a. slope-intercept form b. negative form c. graph form d. standard form what does the vertical line in an augmented matrix represent? a. x - value b. y - value c. equals sign d. line on a graph

QUESTION 1

The given equations are;

and

The augmented matrix is  

This implies that and

The correct answer is A(1,4).

QUESTION 2

To convert a linear equation into an augmented matrix we need to write the equation in the form;

This is referred to as the standard form.

The correct answer is D.

QUESTION 3

When we write a system of equation as an augmented matrix, we use a straight line to separate the coefficient matrix from the constant matrix just like how the equal sign separates the variables from the constants in the standard form.

The straight line represents the equal sign.

The correct answer is C

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
