Solve by the elimination method.
3r 5s =42
is this right.
Decide whteher the pair of line is parallel, perpindular, or n
I said is was parallel. Tell me if this right.
in your first question, you found only the one variable, you still have to find s
Besides that, you have a typo in the second equation.
in your second problem,
the slope of the first equation is -4/5
the slope of the second one is 5/4
notice they are negative reciprocals of each other.
What did you learn about that situation?
can u help me solve this problem
