Answer:
All real numbers
Step-by-step explanation:
4(x+1) = 4x+4
Distribute
4x+4 = 4x+4
Subtract 4x from each side
4x+4-4x = 4x+4-4x
4=4
This is always true so there are infinite solutions
Based on the vertex and table this is the graph.
Answer:
Bottom left
Step-by-step explanation:
It shows that x is a unpredictable number but also show the value of 3 and 7
Answer:
Value of x=4 and y=-13/3
Step-by-step explanation:
We need to solve the systems of equations

Solving using substitution method:
Let:

Find value of x from eq(1) and put in eq(2)

Put value of x in eq(2)

Now, finding value of x by putting value of y in eq(1)

So, Value of x=4 and y=-13/3
