dwayne used row operstions on an augmented matrix representing a system of equations and obtained the following result. how many solutions does dwayne's system of equations have?
Considering the given matrix, it is found that the number of solutions of the system of equations is given by:
B. 1.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The matrix form of the system can also be written as:
[tex]\left[\begin{array}{cc}1&0\\0&1\end{array}\right]\left[\begin{array}{c}x\\y\end{array}\right] = \left[\begin{array}{c}5\\6\end{array}\right][/tex]
Applying the multiplication of the matrices, we have that:
x + 0y = 5 -> x = 5.0x + y = 6 -> y = 6.Hence the system has one solution, given by (5,6), and option B is correct.

A line contains the points (45, - 52) and (48, -65). What is the slope of the line in simplified form?
The slope of the line is -13/3
Step-by-step explanation:
Equation for slope- change in y over change in x
-65-(-52) over 48-45 ... which simplifies to -13 over 3
... -13/3
Prove: a^2+b^2/2 ≥ab
We know that the square of any number is greater than or equal to zero ;
So if have a number like x :
[tex]( {x})^{2} \geqslant 0[/tex]
_________________________________
Now we have a number which is
( a - b ) ;
So we have :
[tex]( {a - b})^{2} \geqslant 0 [/tex]
##############################
Reminder :
[tex]( {a - b})^{2} = {a}^{2} - 2ab + {b}^{2} [/tex]
##############################
So we have :
[tex] {a}^{2} - 2ab + {b}^{2} \geqslant 0 [/tex]
Both sides plus 2ab :
[tex] {a}^{2} + {b}^{2} \geqslant 2ab [/tex]
Divided both sides by 2 :
[tex] \frac{ {a}^{2} + {b}^{2} }{2} \geqslant ab \\ [/tex]

Solve the following system of equations
by substitution:
-X+y= -5
2x - 5y=1
Which ordered pair is the solution?
Help
Answer:
Step-by-step explanation:
y = x - 5
2x - 5y = 1
2x - 5(x - 5) = 1
2x - 5x + 25 = 1
-3x + 25 = 1
-3x = -24
x = 8
y = 8 - 5

What is the rate if change for y = x - 4
Answer:
The rate of change is 1
Step-by-step explanation:
This is because the slope is x, and -4 is just the y-intercept, which has nothing to do with the slope. Because the slope is x, that means that it is positive 1.
Answer:
Rate of Change = 1
Step-by-step explanation:
Rate of Change = Slope = m
y = mx + b
y = (1)x -4
m = 1

please help me with domain and range of graphs Part 1
Answer:
see the attached for domainRange: (-∞, 4], [3, ∞), [-3, 1]Step-by-step explanation:
The domain is the horizontal extent of the graph. When the graph has arrows on the end, it extends to infinity in the indicated direction.
__
The range is the vertical extent of the graph.
Left Graph
We assume the curve is intended to touch, not cross, the line y=4, so the range is ...
range: (-∞, 4]
__
Middle Graph
We assume the graph continues along the line y=3 to the right indefinitely. Then this value is the minimum of the range.
range: [3, ∞)
__
Right Graph
The low point on the graph is at y=-3, and it looks like the graph continues to the right along the line y=1. Then the range is ...
range: [-3, 1]
