Answer:

The first table is correct!

Step-by-step explanation:

If you divide the Y-var by they by the X-var you would get 12 (as an answer) for all of them...which makes them proportional, YW! :D

Use Cramers Rule to solve the system <br> 2x - 3y = 11<br> -6x + 8y = 34

Nastasia [14]

Step-by-step explanation:

given :

2x - 3y = 11

-6x + 8y = 34

find : the solutions of the system by using Cramers Rule.

solutions:

in the matrix 2x2 form =>

[ 2 -3] [x] [11]

[-6 8] [ y] [34]

D =

| 2 -3 |

|-6 8 |

= 8×2 - (-3) (-6)

= 16-18 = -2

Dx = | 11 -3 |

| 34 8 |

= 11×8 - (-3) (34)

= 88 + 102

= 190

Dy = | 2 11 |

|-6 34 |

= 2×34 - (-6) (11)

= 68 + 66

= 134

x = Dx/D = 190/-2 = -95

y = Dy/D = 134/-2 = -67

the solutions = {-95, -67}

URGENT! Can anyone explain how to solve this??

Alex

Check the picture below

the triangles are similar, the angles are congruents then

so... just add them up, and divide by 2, or set them as rational
