So to start subtract $5 from $16.25 for the monthly membership
That gives you $11.25
So then you Just divide...
$11.25 divided by $1.25
which gives you 9
So bill rented 9 movies for the month
Hope this helped! :)
Direct variation is of the form y=kx. We are given the point (8, -4) so we can solve for k, the constant of variation...
-4=8k, divide both sides by 8
-4/8=k
k=-0.5, so our equation is:
y=-0.5x,
797,100 deaths x
---------------------------------- = -------------------------
350,000,000 people 100,000 people
or:
797,100 deaths x
--------------------------- = -----------------
3500 people 1 people
Result: 228 deaths per 100,000 people
slope = (y2-y1)/(x2-x1) (x1,y1) = (2,-5) (x2,y2) = (7,1)
= (1- (-5))/(7-2)
= (1+6)/(5
7/5
m=7/5
