Operations that can be applied to a matrix in the process of Gauss Jordan elimination are :
replacing the row with twice that row
replacing a row with the sum of that row and another row
swapping rows
Step-by-step explanation:
Gauss-Jordan Elimination is a matrix based way used to solve linear equations or to find inverse of a matrix.
The elimentary row(or column) operations that can be used are:
1. Swap any two rows(or colums)
2. Add or subtract scalar multiple of one row(column) to another row(column)
as is done in replacing a row with sum of that row and another row.
3. Multiply any row (or column) entirely by a non zero scalar as is done in replacing the row with twice the row, here scalar used = 2
Answer:
G = -4x - 4
x = -1
Step-by-step explanation:
step 1: flip your equation and turn G into zero
ex: -4x - 4 = 0
step 2: add 4 to both sides
ex: -4x - 4 + 4 = 0 + 4 (-4x = 4)
step 3: divide both sides by -4
ex: -4x/-4 = 4/-4 (x = -1)
step 4: plug -1 into x then solve to check your answer
ex: -4(-1) - 4 = 0
4 - 4 = 0
0 = 0 (when this says 0 = 0 then that means your answer is always true)
3 4/5 because if 5 only goes into 19 3 times and then there is 4/5 left
Answer:
The length would be 5 meters
Step-by-step explanation:
To get this value, start with the area formula.
A = LW
Next input the known values for area and width
1 = L1/5
Now multiply each side by 5
5 = L
Parallel lines have equal slopes. so the equation y=-4x+5.has slope of -4 because this is in slope intercept form y=mx+b where m is slope.
so we know a parallel line will have slope -4
we have a point on the line so we will use point slope formula to solve.
y-y1=m(x-x1) where (x1,y1) is point on line
so we get
y-4=-4(x-0) to put in slope intercept form we solve for y
y-4=-4x
y=-4x+4 is an equation of a line parallel to y=-4+5 passing through (0,4)
