119 ÷ 9 = 13 2/9
702 ÷ 9 = 78
432 ÷ 9 = 48
641 ÷ 9 = 71 2/9
372 ÷ 9 = 41 3/9 ⇒ 41 1/3
702 and 432 are divisible by 9. The rest are not.
I'm assuming the function is f(x) = 100(0.7)^x. This is the same as y = 100(0.7)^x because y = f(x).
Plug in x = 0 to get
y = 100(0.7)^x
y = 100(0.7)^0
y = 100(1)
y = 100
So (x,y) = (0,100) is one point on this function curve
Plug in x = 2 to get
y = 100(0.7)^x
y = 100(0.7)^2
y = 100(0.49)
y = 49
So (x,y) = (2,49) is another point on this curve
In summary, the two points on this function curve are (0,100) and (2,49)
Eazy 44,756
then you do 167 not take 447 the first part of the first number now can 167 go into 447 yes it can then from there wants you have leftover numbers then add 5 to the leftover and see if 167 can go into it from there take the last digit from 44,756 and there you go
That is a horizontal straight line, so the slope is 0.
B would be correct. The first two people, out of 100, would have painted 42.5/100 of the building.
