Answer:
-9 < x
Step-by-step explanation:
6x-11-13x<7-5x
Combine like terms
-11-7x<7-5x
Add 7x to each side
-11-7x+7x<7-5x+7x
-11 < 7+2x
Subtract 7 from each side
-11-7 < 7-7+2x
-18 < 2x
Divide by 2
-18/2 < 2x/2
-9 < x
1/5(x-y) = 1
x+y = 9
x-y = 5 (x5)
x+y = 9
First you want to create both equations so at least one of the variables (x or y) are the same in both equations, so that is why I multiplied the top one by 5, you multiply the whole equation (both sides)
2x = 14
x = 7
Then you either Plus or minus one from the other, I plused the top one onto the bottom one, then solved for x
7 + y = 9
y = 2
Then put x back into one of the first two equations to get Y
Use the distance formula to get the answer.
(-4-(-2))*2+(-2-2)*2
-2*2+4*2
4+16=20
Then you simply 20
