Answer:

Step-by-step explanation:
We have to simplify the given exponential exponents.
Exponential Properties:
Simplification takes place in the following manner:
a)

b)

c)

d)

Since the y coordinate is the same for both points we only need to know the change in the x coordinates to find the distance between these two points.
5--12=17
So these two points are 17 units apart.
Answer:
B
Step-by-step explanation:
I chose the answer B because there is no there should be no exponents to make the answer linear
Answer:
4
Step-by-step explanation:
x+9<4x
Subtract x from each side
x-x+9<4x-x
9 < 3x
Divide each side by 3
9/3 < 3x/3
3 < x
X must be greater than 3
