The augmented matrix is,
We have given system of linear equation is,
<h3>What is the meaning of augmented matrix?</h3>
In an augmented matrix, each row represents one equation in the system and each column represents coefficients (with signs) of variables or the constant terms.
So, the first row is
the second row is
and the third row is
Therefore the augmented matrix for this linear system is,

(17/70)x = 70/70(17x)/70 = 70/7017x = 70x = 70/17x ≈ 4.1176
Answer:
D
-5x + y = 7
x+3y = 5
Step-by-step explanation:
when you graph the equations, they are parallel. as you know, solutions are the point where the lines meet. if they are parallel, it's not possible for the lines to intersect.
Answer:
only one solution
Step-by-step explanation:
Complete question:
<em>Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x − y = 2 3x + y = −6 one and only one solution infinitely many solutions no solution Find the solution, if one exists. (If there are infinitely many solutions, express x and y in terms of the parameter t. If there is no solution, enter NO SOLUTION.) (x, y) </em>=
Given the expression
2x − y = 2 .... 1
3x + y = −6 ..... 2
We are to determine the number of solution the equation has:
Add equation 1 and 2
2x + 3x = 2 - 6
5x = -4
x = -4/5
Substitute x = -4/5 into 1
From 1: 2x − y = 2 .... 1
2(-4/5) - y = 2
-8/5 - y = -2
-y = -2+8/5
-y = -10+8/5
-y = -2/5
y = 2/5
<em>Since the value of x and y are just 1 hence the system of equations has ine solution</em>
Answer:
-44.58%
Step-by-step explanation:
If I spent $83 on a coat and the next week found it for $46, how much did it change? Well 83-46 is $37 and is -$37 because that's how much money I lost. To find the percent change we divide the difference of -37 by the total 83.
-37/83= - 0.44578
To convert from a decimal to a percent, I multiply by 100.
-0.44578(100)= -44.58 rounded.
