Step-by-step explanation:
Ends in 4
Answer:B
Step-by-step explanation: x is less than 1 so it is a open circle on the graph and x is greater than or equal to -1 so it is a closed circle on -1, B has both of these so B is the answer
Answer: slope= -3,5
Step-by-step explanation:
Answer:
D. Infinitely many solutions
Step-by-step explanation:

1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding
to both sides.
Like this: 
ending up with 
2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.
Like this 
Ending with 
3.Now, we can plug the expression
into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.
Like this 
4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.
