Given the augmented matrix 1 -1 -5 2 -1 -4 0 2 5 perform each row operation in the order specified and enter the final result. First: R₂-2R₁ → R₂, Second: R3+ 4R₁ → R3, Third: R3 + 4R2 → R3. A = 4 -2 1000 0000 000 сл

The figure to the right shows the letter L in a rectangular coordinate system. The figure can be represented by the matrix B, shown to the right. Each column in the matrix describes a point on the letter. The order of the columns shows the direction in which a pencil must move to draw the letter. The L is completed by connecting the last point in the matrix, (0,9), to the starting point, (0,0). Use these ideas to complete parts (a) and (b) below. a. If A = AB - 1 0 [!!] 0 1 find AB. (Simplify your answer.) b. Graph the object represented by matrix AB. What effect does the matrix multiplication have on the letter L represented by matrix B? Choose the correct graph below. A. O B. Rotates the letter L about the origin. Reflects the letter L across the x-axis. O C. Q 077 11 0 B-[07718] 001 199 B= Reflects the letter L across the y-axis.

Use the given inverse of the coefficient matrix to solve the following system. 5x₁ + 3x₂ - 6x₁ - 3x₂ = - 12 -2 = and x₂ = B. There is no solution. A-1 = - 1 N - 1 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. о А. х1 53 (Simplify your answers.)

I would like to request the written form RREF without fractions.I am having a hard time doing RREF

What volume of each of a 5% acid solution and a 65% acid solution should be combined to form 46 ml of a 50% solution? Set up the appropriate equations and solve the system using the inverse of the coefficient matrix. Combine O ml of the 5% acid solution withO mL of the 65% acid solution to form 46 mL of a 50% solution. (Type integers or decimals. Round the final answers to two decimal places as needed. Round all intermediate values to two decimal places as needed.)
