Lena [83]

Answer:


Step-by-step explanation:

X+Y = 13

 

$18 + $22 = $258

OR

18X+22Y=258

 

18X + 22(13 - X) = 258

 

18X + 286 - 22X  = 258

 

286 - 4X  = 258

 

-4X= 258 - 286

 

-4X = -28

 

X= 7

Y=6

 7 of the X tour  packages & 6 of the Y tour  packages

50 POINTS FOR THE CORRECT ANSWER !!!!!!
Stels [109]

Answer:

y = 9.8x + 6.7

y = 6.7x + 9.8

y = 7.5x + 3.8

y = 3.8x + 7.5

Step-by-step explanation:

I made 2represent x.

y= 9.8(2) + 6.7

y = 26.3

y=6.7(2) + 9.8

y= 23.2

y= 7.5(2) + 3.8

y= 18.8

y= 3.8(2) + 7.5

y= 15.1

Y=1/3x+4 going through the point (9,-2)
Art [367]
Substitute x=9 and y=-2 into equation,
Left hand side=-2
Right hand side=1/3(9)+4= 3+4=7

Because LHS doesn’t = with RHS, the point (9,-2) doesn’t satisfy with the equation

Therefore the point doesn’t go through y=1/3x +4.
