The point (17, 0) lies on the line 8x + 11y = 136. Determine if this point is a solution of the system
8x + 11y = 136

0x – y = -8

Question

The point (17, 0) lies on the line 8x + 11y = 136. Determine if this point is a solution of the system 
8x + 11y = 136

0x – y = -8

somone please help

jim_thompson5910 · Answer

Is the second one really  0x – y = -8 ???

anonymous · Answer

YE

anonymous · Answer

YES

jim_thompson5910 · Answer

0x – y = -8 

-y = -8 

y = 8


Notice how this is not the same as the y coordinate of (17,0). So (17,0) is not a solution

anonymous · Answer

THAT ALL I HAVE TO DO YOU MADE IT SEEM SO EASY WOW

jim_thompson5910 · Answer

yeah that's why I wanted to check with you whether it was 0x-y = -8 or not

anonymous · Answer

YOU THINK YOU UNDERTAND THIS QUESTION


. Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this. 
-x + 2y = 8

-x + 10y = 48

jim_thompson5910 · Answer

change the signs of each term in the first equation to get x-2y = -8


Then add the equations

  x   -   2y = -8
-x   + 10y = 48
---------------
 0x + 8y = 40

So we have 8y = 40

Solve 8y = 40 for y
