any answer choices? c:
yes 6,1 8,-1 6,2 6,-2
graph) or test each option by plugging in x and y values into both inequalities and see which one comes out as a true statement
im thinking its 6,-2
oops i meant 6,2
how do you know ?
7-5 is 2
\[\rm x-y \ge 7\] this the first inequality substitute (6,2) for x and y do you get true statement at the end ? :=))
ooo no
8,-1
how ?? post the work remember you should test by plugging into *both* inequality
k im going to try thanks
what does that symbol mean
same???
\[\ge \] means left side value MUST greater than or equal to right side in order to make a true statement \[x \ge 2\] x is ` greater than or equal` to 2 x can be 2 or greater than 2
its 6,-2
thank u
did you plugg into 2nd inequality bec the order pair should be true for both inequalities
im sooo confused
forget it its too hard i will wait i am in special ed
you have to inequalities \[\rm x-y \ge 7\] AND \[x+2y < 5\]you should substitute x and y into BOTH inequalities what do you get when (x,y)= did you replace x and y for 6,-2 into x+2y <5 ???
yaay but i just dont know
you don't know what ?
what did you get at left side ?? x+2y <5 substitute (X,y) for (6,-2) simplify left side what number would you get ?
6+2*-2right
yes what would be the final answer ? simplify that 6+2(-2) ?
2
so you get 2 at left side now is it true statement 2 <5 ???
ooooh wow i was thinking the other way the symbol oh gosh thanks for explaining
2 <5 means 2 is less than 5 is it true ?? |dw:1452749208179:dw|
