Answer 1

@calculusxy @jim_thompson5910 i am pretty sure it is either b or d hold on one sec...

Its B

Answer 5

with proof plz?

Answer 6

i wanna know how to do this stuff

Answer 7

@BarfBag Please show work. I did not get B as the correct option.

Answer 8

2(5)-5(3)=-5 --> 10-15=-5 -----> -5=-5

Answer 9

oh wait wait wait wait is this proof?

Answer 10

2x-5y=-5 | x+2y=11
2x-5y=-5 | 2x+4y=22
Subtract the first equation form the second.
9y=27
y=3
Then substitute.
x+2(3)=11
x+6=11
x=5
The final answer is the ordered pair (5,3).

Answer 11

@Directrix what did u get?

Answer 12

5+2(3)=11--->5+6=11---->11=11
