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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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):

+

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

OpenStudy (anonymous):

ok bye
