25% = 1/4
So to get the unknown number, multiply 9 by 4:
9 × 4 = 36
C because 1/4 times 1/2 equals any of this numbers
Awenser
There would be 5 because 5times 4 is 25 and that make 25 dollars to prove this is write take 20 and dvide it by 4 then you get 5 so then you no it cost 5 dollars per attendy
I would say D because if you do 10 x 2 you get 20 then minus 9 equals 11 and that seems around the right measurements
Average rate=(change in y)/(change in x)
if f(x)=-x/3
r=( f(2)-f(-2) )/(2--2)
r=(-2/3-2/3)/(2+2)
r=(-4/3)/4
r=-4/12
r=-1/3
For a line, this is always true, since all lines have a constant velocity, the average velocity over any interval is equal to the slope.
