The first picture about the rational numbers I am not sure the answer.
In the second picture the set that are all equivalent to the fraction is the second set.
In the third picture
the equivalent expression is the first one.
In the fourth picture the correct situation is the first one about buying popcorn.
Hope this helps a little, sorry I could not help more.
The answer is C. It has the wrong graph labels.
The equation of this parabola will have the form f(x) = a(x+5)(x-4), which works out to f(x) = a(x^2 + x - 20). Since the parabola passes thru (3,40),
40 = a(3^2 + 3 - 20), or 40 = a(-8), so a = -5.
Thus, the equation of this parabola is y = -5(x^2 + x - 20).
Step-by-step explanation:
When two lines are parallel,their slopes are equal.
Given line is 
.
Let 
be the slope of the line.
.
It is given that the line passes through the point 
.
The equation of the line passing through 
and has slope is 
So, the equation is 
which simplifies to
