What do you need my friend?
OpenStudy (anonymous):
Two bees have found a food source. The first bee’s path to the hive follows the line\[y=\frac{ 4 }{ 5 }x\] . The second bee’s path follows the line\[y=-2x-3\] . Their paths cross at the hive. Use substitution to solve the problem.
What are the coordinates of the hive?
OpenStudy (anonymous):
Srry its \[y=-2x+3\]
OpenStudy (anonymous):
This question is beyond my scope my friend, I apologize
OpenStudy (anonymous):
yeah mine too. okay thanks

No problem. What type of mathmatics is this?
OpenStudy (anonymous):
Uh. Algebra B
Topic: Solving Systems of Equations
OpenStudy (anonymous):
Ahh.
OpenStudy (anonymous):
yep
OpenStudy (anonymous):
You have to solve one equation for x, and plug it into the second one

ok how
OpenStudy (anonymous):
So if you solve y=-2x-3 for x, you get -2x=-y-3, which then becomes x=(-y-3)/-2
OpenStudy (anonymous):
Then you literally plug that equation into the other one when there is an x
OpenStudy (anonymous):
it is -2x+3
OpenStudy (anonymous):
+

No, you plug (-y-3)/-2 into y=(4/5)x for x. That is y=(4/5)((-y-3)/-2). Then you distribute the 4/5
OpenStudy (anonymous):
no, ooops im sorry the equation is y=-2x+3 you entered y=-2x-3 sorry to confuse both of us
