Solve and enter the value for x. If necessary round answer to 2 decimals. 5−3(x-4)=2x-3 

For the given circle, enter the requested values. ( x – 3 ) 2 + ( y + 5 ) 2 = 64 Important: Do not enter any extra spaces when entering answers. Enter the x-value of the center of the circle here: x=[BLANK-1] Enter the y-value of the center of the circle here: y=[BLANK-2] Enter the radius of the circle here: r=[BLANK-3]

Solve the system of equations for the x value using matrices (row operations).

Use augmented matrices to find the inverse, if it exists:

Which of the following are NOT allowable operations when the Gaussian elimination method is used to solve a system of linear equations?(i) A multiple of elements of one row may be added to the corresponding elements of any other row.(ii) Any two columns may be interchanged.(iii) All elements of any row may be squared.(iv) All of the elements of any row may be multiplied by any nonzero number.

Graph the system of equations:             x+y=202x-y=10

Solve the system of equations. 2x-y+5z=-7x+y-2z=-2x-y+4z=-4

Match each operation with it’s correct answer.

How many solutions does each system of equations have? You can graph to find the answers or solve algebraically. (Each ordered pair (x,y) is one solution.)

Perform the row operation(s) on the given augmented matrix in the order given. a )   – 4 R 1 + R 2 → R 2 b )   – 2 R 1 + R 3 → R 3 c )           5 R 2 + R 3 → R 3
