Answer:
There are 8 vertices.
Step-by-step explanation:
We have been given the expression

We have to write this expression in the form 
In order to write the given expression in this form, we can use some exponent property.

On using the property (1), we have

Now, on using the property (2), we get

Therefore, the simplified form of the given expression is

Answer:
The first one is correct.
Step-by-step explanation:
I know a thing or two about a thing or two about powers of 10.
Answer:
y = x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 9 ← is in slope- intercept form
with slope m = 1
Parallel lines have equal slopes, thus
y = x + c ← is the partial equation of the parallel line
To find c substitute (6, - 7) into the partial equation
- 7 = 6 + c ⇒ c = - 7 - 6 = - 13
y = x - 13 ← equation of parallel line
