Matrix :

1    4    4

5    2    2

1    5    5

=> Determinant =

1 * (2*5 - 2*5) - 4 * (5*5 - 1*2) + 4 * ( 5*5 - 2*1)

= 1*(10 - 10) - 4*(25 - 2) + 4*(25 -2) = 1*0 + 4* 23 + 4*(25 - 2) = 0 - 4*23 + 4*23 = 0

How to graph 14x+18y=126
Burka [1]

  • We need to rearrange this into y=my+c
  • Subtract 14x from both sides
  • 18y=-14x+126
  • Divide both sides by 2
  • 9y=-7x+63
  • Divide both sides by 9
  • y=\frac{-7x+63}{9}=\frac{-7x}{9} +\frac{63}{9}
  • Plot the point (0, 63/9)
  • Then pick some x values and put them into the equation to find the respective y values
  • Then plot those points
  • Finally join up those points

Solve the following: S5 for 600 + 300 + 150 + .
Tresset [83]
600 + 300 + 150 + . . . is a geometric sequence with a = 600 and r = 1/2
Sn = a(1 - r^n)/(1 - r)
S5 = 600(1 - (1/2)^5)/(1 - 1/2) = 600(1 - 1/32)/(1/2) = 1,200(31/32) = 1,162.5
