Answer:
Step-by-step explanation:
x-y=5
-x+y=5
or x-y=-5
so it is a system of two parallel lines.
so no solution.
or they do not intersect atmany point.
864/12 = the rate per hour, which would be 72 mph. To find how many miles she would drive at the same rate, multiply the 72 (miles) with 9 (hours) which is equal to 648 miles
Answer:
Option 3
Step-by-step explanation:
Since lines a and b are intersecting, x+5=2x-5. Because they are vertical angles.
x+5=2x-5
2x-x=5+5
x=10
Given:
The polynomial function is
Yuri thinks that 
is a root of the given function.
To find:
Why cannot be a root?
Solution:
We have,
If is a root, then the value of the function at is 0.
Putting 
in the given function, we get
Taking LCM, we get
Since the value of the function at is not equal to 0, therefore, is not a root of the given function.
