The function is increasing on the intervals (-infinity, -2.5] and [1, infinity)
Answer:
Option C (1, 0)
Step-by-step explanation:
We have a system with the following equations:

The first equation is a parabola.
The second equation is a straight line
To solve the system, substitute the second equation in the first and solve for x.

Simplify

You must search for two numbers that when you add them, obtain as a result -2 and multiplying both results in 1.
These numbers are -1 and -1
Therefore

Finally the solutions are

Answer:
Value of x is 2
Step-by-step explanation:
Given
BD = 6
DA = 4
BE = 
EC = x
Also segment DE is parallel to segment AC
∴ By using Midpoint theorem which states

Putting the given data in above equation we get

It’s very simple divide 22,189 by 15.... the answer 1,479 hope I helped!
