There will be one solution. To solve that:
1. Get the y alone by switching the places.
6x+y=2 > y=2-6x
-18x+3y=12 > 3y=12-18x > Then divide 3 on each number > y=4-6x
After doing that, you can solve this in graphing or algebra way.
Ima do the algebra way:
SO we have 2 system of equations. Now pick one equestion.
I will pick, y=2-6x. Now Ima replace the Y with the other equation y=4-6x >
4-6x=2-6x.
Now solve. And get > 0 aka Infinite Solution.
Answer:
C for the graph:
Domain:{-3,-1,0,3}
Range:{-1,0,1,2,3}
A for the table:
Domain:{-2,0,2,4}
Range:{-3,-1,0}
Step-by-step explanation:
For the graph:
The Domain is moving across the graph horizontally, the Range is moving up the graph vertically.
It has to be C because when moving across it starts with -3 and ends with 3, and no other answer choice says that. Also when moving up, it starts with -1 and ends with 3, and no other choice but C does that.
Now for the table:
The range is the y values and the domain is the x values.
A is the only choice where the y values match the range and the x values match the domain.
Hope this helps
Answer:
-a + 7b
Step-by-step explanation:
This problem is asking you to simplify the equation.
In order to do this, we will combine like terms (like terms are terms that share the same variable and/or exponent).
So we will combine 3a and -4a to get -1a or just -a, and now we'll combine 5b and 2b to get 7b.
So all together we have -a + 7b.
Hope this helps you :)
Combined speed = 95+75= 170 mph
they will meet in 306/170 = 1.8 hours or 1 hour 48 minutes.
I would be 2
i think i hope that works for you
