Answer:
when you subtract a negative number the two negative signs cancel out and it turns to a positive number
Step-by-step explanation:
in -6 - (-2)
the two - signs cancel out so it ends up being
-6+2 which is why it equals -4
I is the right one because it is a half and they both look the same
Answer:
(5,19) lies on the graph of the transformed function y = f(1/5x)
Step-by-step explanation:
Suppose (1,19) is on the graph of y = f (x)
the graph of the transformed function y = f(1/5x)

1/5 is multiplied with x in f(x)
1/5 is less than 1 so there will be a horizontal stretch in the graph by the factor of 1/5
To make horizontal stretch we change the point
f(x)=f(bx) then (x,y) --->( x/b,y)
We divide the x coordinate by the fraction 1/5
(1,19) ----> 
So (5,19) lies on the graph of the transformed function y = f(1/5x)
Answer:
(16) 0 (17) 36
Step-by-step explanation:
8-3 = 5
5x5 = 25
25 / 25 = 1
1 - 1 = 0
and 81 / 9 x 4 = 9 x 4 = 36

Answer:
r = √(V/(πh))
Step-by-step explanation:
To solve for r, "undo" what has been done to r. The "undo" is generally in the reverse order. Here, we have ...
- r is squared
- the square is multiplied by πh
To undo these operations, we ...
V/(πh) = r² . . . . . . . . divide by πh
√(V/(πh)) = r . . . . . . take the square root
r = √(V/(πh))
