9mph because 20 minutes time 3 is one hour so multiply 3 by 3 to get 9
F(x) = 3x + 2x = 3f-1(x) + 2x - 2 = 3f-1(x)(x - 2)/3 = f-1(x)(14 - 2)/3 = f-1(14)12/3 = f-1(14)4 = f-1(14) f(f-1(14)) = f(4)f(4) = 3(4) + 2f(4) = 12 + 2f(4) = 14 A function and its inverse are inverse operations, like addition and subtraction. They undo each other. f(f-1(x) = x
Answer:
C
Step-by-step explanation:
I am guessing that's it.
Answer:
None of the points is a solution
The question doesn't look logical correct, check closely
Step-by-step explanation:
With the points ;
(1,-1)(1,−1)
The slope is = ( -1-( -1))/( 1-1)= infinity
Similarly if you do same with
5,-7)(5,−7) ; the slope would be infinity
