Answer:
Graph 3.
Step-by-step explanation:
|x| + 3 > 7
|x| > 4
This means x > 4 or x < -4,
which is the third graph.
Answer:
The equation for your graph is Y=2x+1
First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.
∠ABC=∠CDA=72º
∠DAB=∠BCD=x
∠ABC+∠CDA+∠DAB+∠BCD=360º
Therefore:
72º+72º+x+x=360º
144º+2x=360º
2x=360º-144º
2x=216º
x=216º/2
x=108º
So, <span>∠DAB=∠BCD=x=108º
Answer: </span>∠DAB=108º (B)
