Answer:
B = (C-Ax)/y
Step-by-step explanation:
Solve for B.
Ax+By=C
making B the subject of formula '
Ax+By=C
subtract Ax from both sides
By = C-Ax
By = C-Ax
divide both sides by y
B = (C-Ax)/y
Answer: - 49
Step-by-step explanation:
f(x) = -2x - 1
g(x) =
- 1
fg(x) = f (
- 1) , we just put in the value of g(x) , the next thing is to substitute
- 1 for the value of x in f(x) , that is
fg(x) = -2(
- 1) - 1
fg(x) = -2
+ 2 - 1
fg(x) = -2
+ 1
Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is
fg(-5) = -2 (
+ 1
fg(-5) = -2(25) + 1
fg(-5) = -50 + 1
fg(-5) = -49
Step-by-step explanation:
Question 3) there's 60 minutes in a hour
3 times 60 = 180 books in 1 hour
3 times 180 = 540 books in 3 hours
540 + 180 + 180 = 900 books in 5 hours
The difference between those numbers : 900-540= 360 and 540-180= 360 so every 2 hours 360 books is done each time so just add 360 books each time for every 2 hours added
