Chose parameters h and k such that the system has a) a unique solution, b) many solutions, and c) no solution. x1 + 3x2 = 4 2x1 + kx2 = h

a) k=1, h=1, the unique solution of the system is  

b) If k=6 and h=8 the system has infinite solutions.

c)If k=6 and h=3 the system has no solutions.

Step-by-step explanation:

The augmented matrix of the system is . If two times the row 1 is subtracted to row 2 we get the following matrix .

Then

a) If k=1 and h=1, the unique solution of the system is and solviong for ,

Then the solution is

b) If k=6 and h=8 the system has infinite solutions because the echelon form of the matrix has a free variable.

c)If k=6 and h=3, the system has no solutions because the last equation of the system of the echelon form of the matrix is

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
