Not that it will help all that much, but you could take out 9 as a common factor.
9(x^2 - 7x - 78) = 0 so since 9 but itself can't produce a zero, we can divide by 9
x^2 - 7x - 78 = 0
There are 3 factors of 78
2 13 and 3
6 and 13 differ by 7 (6 comes from putting the 2 and 3 together by multiplying.
(x - 13)(x + 6) = 0
x -13 =0
x = 13
x + 6 = 0
x = - 6
The two zeros are (-6,0) and (13,0)
The answer to your problem is 1,795.5
x = 3
2x + 7 =....
2 (3) + 7 = 6 + 7 = 13
this is my answer how about my answer ?

Step-by-step explanation:
Again, let us begin by finding the equation of the line
The y-intercept is 0 and the slope is 1, so the equation of this line would be
or just 
We can see that the shaded region is ABOVE the line, so we would use a greater than (>) sign.
This as the line is shaded in, we must also include that line in the inequality. This means that we will instead use the
sign.
This means that our answer would be
