Answer:
![y^2 + 2y + 80](https://tex.z-dn.net/?f=y%5E2%20%2B%202y%20%2B%2080)
Step-by-step explanation:
![6y^2 + 2y + 5 - (5y^2 - 64 - 11)](https://tex.z-dn.net/?f=6y%5E2%20%2B%202y%20%2B%205%20-%20%285y%5E2%20-%2064%20-%2011%29)
[pay attention to the signs :)
![y^2 + 2y + 80](https://tex.z-dn.net/?f=y%5E2%20%2B%202y%20%2B%2080)
3(x+5) = -4x+8
3x+15=-4x+8
3x+7=-4x
7x+7=0
x=-1
(I think this is the only solution!)
Answer:
no its not
Step-by-step explanation:
You would have to multiply 9w times -12 and 0 times -12 which does not equal the equation
Answer:
x = -2
Step-by-step explanation:
Since this is a vertical line, the equation of the line will not be in y = mx+b form. The slope of the line is undefined. So, the equation will be x =.
To figure out what x equals, look at all the x values in the coordinates or look to see where it crosses the x axis, which is at -2.
The equation is x = -2.
