Answer:
The answer is A, 14 inches.
Answer:
-5x^2-2x
Step-by-step explanation:
When distributing, you multiply the term outside the brackets to all the terms in brackets.
If the term outside the bracket is negative, then when distributing/opening the brackets, the signs of the terms changes.
So in this prob. -x would multiply to both +5x and +2
-x*5x+-x*2
∴-5x^2-2x
y=f(x) intersect y=g(x) means that f(x)=g(x) =>

Answer: x=7
Answer:
Option C is correct.
The y-intercept of the graphed function is; 
Explanation:
To find the y-intercept of the graphed function:
The point where the graph crosses the y-axis is call y-intercept.
You can also find the y-intercept by looking at the given graph and seeing which point crosses the y-axis also this point will always have an x-coordinate of 0.
End behavior of a polynomial function is the behavior of the graph of function as x approaches
or
Also, the degree and the leading coefficient of a polynomial function determine the end behavior of the graphed function.
therefore, the y-intercept of the graphed function is; (0, -9)
