EXPLANATION
The given function is
When we compare this function to
We have a=1, b=4 and c=5
We put this inside the formula for the discriminant, which is
Since the discriminant is negative, the function has no x-intercepts.
The graph of this function is the one hanging in the air above the x-axis and opens upwards.
Answer:
7 x > 4 x + 100
7 x - 4 x > 100
3 x > 100
x > 100 : 3
x > 33.33

Step-by-step explanation:
I got 6 and -7 when I did this problem, maybe you made a mistake or maybe I did. But you are on the right track
six times a number: 6(x)
The sum of 6(x) and 25: 6x + 25
6x + 25 is your expression.
hope this helps
