Answer:
(fog)(x) = 4x - 7
Step-by-step explanation:
f(x) = 2x-1 and g(x) = 2x-3;
(fog)(x) = f(g(x)
= f(2x - 3) = 2(2x - 3) - 1
= 4x - 6 - 1
= 4x - 7
Answer:
The numbers less that 40 which have sum of digits 8 are 17, 26, 35.
Only one of those that has a factor of 7. And that is 35.
So you are 35.
Second way:
The numbers less that 40 which have a factor of 7 are 7,14,21,28,35
Only one of those which has sum of digits as 8. And that is 35.
So you are 35.
Step-by-step explanation:
Answer:
3 hours
Step-by-step explanation:
Recall:
Distance = speed x time
we are given that speed = 18 km/h and distance = 54 km.
hence,
54 = 18 x time (divide both sides by 18 and rearrange)
time = 54/18 = 3 hours
