F(x)=4+6+5/4+1
F(x)=4+6+5/5
F(x)=10+1=11
Answer =11
Let cats = X
Then doges = 6x ( 6 times as many cats, so multiply 6 by number of cats)
Now you have X + 6X = 35 ( number of cats plus number of doags equal 35)
X +6x = 35
Simplify:
7X = 35
Divide both sides by 7 to solve for x:
X = 35 / 7
X = 5
Cats = X, so there are 5 cats.
Dogs = 6X = 6(5) = 30 total dogs.
Answer:
f(x)=8x +118
Step-by-step explanation:
One would have to know how many miles the trucker travels in a year. It appears as if that data is not provided. Once that total mileage per year is known, then divide that value by 10,000 to yield the number of oil changes in a year's time.
Answer:
Step-by-step explanation:
To prove that 
is a multiple of 7.
Proof by induction:
Let n =1. Then we have 8-1 =7 is a multiple of 7
Thus the P(1) is true.
Let us assume that P(n) is true.
= 7l is true for some integer l
To check for P(n+1)
=LHS
=
Thus we find that this is also a multiple of 7.
If true for n, then true for n+1
Hence we find that since true for 1, we have it is true for all natural numbers.
