Given the system of linear equations:

Vanyuwa [196]

Answer:

Step-by-step explanation:

hello :

Part A : x+6y =6 means : 6y = - x+6

so : y = (-1/6)x+1 an equation for the line (D)

y = (1/3)x -2 is the line (D')

PartB : solution of the system : y = (-1/6)x+1 ....(1) color red

y = (1/3)x -2 ....(2) color bleu

is the intersection point : (6 ; 0)

PartC : Algebraically by (1) and (2) : (-1/6)x+1 = (1/3)x -2

(-1/6)x - (1/3)x = -2-1

(-x-2x)/6= -3

-3x = -18

so : x = 6 put this value in (1) or (2) : y = (-1/6)(6)+1 =0 the solution is : (6 ;0)

Answer:

1/18

Step-by-step explanation:

$( {2}^{ - 3} \times {16}^{ \frac{1}{2} } ) \div ( {81}^{ \frac{3}{4} } \times {27}^{ - \frac{1}{3} } ) \\ \\ =( {2}^{ - 3} \times {2}^{ \frac{4 \times 1}{2} } ) \div ( {3}^{ \frac{4 \times 3}{4} } \times {3}^{ - \frac{3 \times 1}{3} } ) \\ \\=( {2}^{ - 3} \times {2}^{ 2} ) \div ( {3}^{ 3 } \times {3}^{ - 1 } ) \\ \\=( {2}^{ - 3 + 2} ) \div ( {3}^{ 3 - 1 } ) \\ \\ = {2}^{ - 1} \div {3}^{2} \\ \\ = \frac{1}{2} \times \frac{1}{9} \\ \\ = \frac{1}{18}$
