60% is the percent
x is the part
175 * 0.60 = 105
The ratio is 4/5. They both can be reduced down by 9.
Answer:
The function is increasing for all real values of x where
x < –4.
Step-by-step explanation:
we have

This is a vertical parabola open downward (the leading coefficient is negative)
The vertex (h,k) represent a maximum
The roots of the function (or x-intercepts) are x=-6 and x=-2
The x-coordinate of the vertex is the midpoint of the roots
so

The y-coordinate of the vertex is
substitute the x-coordinate of the vertex in the quadratic equation



The vertex is the point (-4,4)
The function is increasing in the interval (-∞,-4)
The function is decreasing in the interval (-4,∞)
Answer:
x=4
