First you need to change 45 feet to 540 inches.
Now you can compare the two ratios:
1 : 25 and 25 : 540
We now need to change the second ratio to a unit rate:
25:540 as a unit rate would be 1 : 21.6 and this is steeper than the a 1 : 25 drop
So, your answer would be: pipe drops to much vertically to function properly
The only number equal to zero is zero.
Answer: a = 0
We are given function f(x) =3x-12
We have to find the value of f(2), that means we plug x as 2 in the given equation
f(2) = 3(2)-12
f(2) =6-12
f(2)=-6
Answer f(2)=-6
