G(x)=x-4 Can you evaluate this problem if so how?
Answers
You cannot evaluate for (g o f)(0). You will get an undefined answer.
(g o f)(x) tells you to plug in the f(x) function for the x-variable in the g(x) equation; so it would be like saying g(f(x)). This would result in (g o f)(x) = (1/x) - 4. Now plug in 0, (g o f)(0) = 1/0 - 4. One cannot divide by zero in order to simplify the equation and get an answer... unless an undefined answer counts, which I'm pretty sure it doesn't.

System of equations that can be used to find the price of one drink and the price of one bag of popcorn is:
3d + 10p = 41
2d + 2p = 11
Price of a bag of popcorn is $ 3.5
Solution:
Let "d" be the price of one drink
Let "p" be the price of 1 bag of popcorn
Luke spends total of $41 on three drinks and 10 bags of popcorn
3 drinks x price of one drink + 10 bags of popcorn x price of 1 bag of popcorn = 41
3d + 10p = 41 ------ eqn 1
Christopher spend a total of $11 on two drinks and two bags of popcorn
2 drinks x price of one drink + 2 bags of popcorn x price of 1 bag of popcorn = 11
2d + 2p = 11 ------- eqn 2
Eqn 1 and eqn 2 represents system of equations that can be used to find the price of one drink and the price of one bag of popcorn
Let us solve eqn 1 and eqn 2 to find values of "d" and "p"
Multiply eqn 2 by 5
10d + 10p = 55 --- eqn 3
Subtract eqn 3 from eqn 1
3d + 10p = 41
10d + 10p = 55
(-) ------------------------
-7d = -14
d = 2
From eqn 2,
2d + 2p = 11
2(2) + 2p = 11
4 + 2p = 11
2p = 7
p = 3.5
Thus price of 1 bag of popcorn is $ 3.5 and price of one drink is $ 2

The solution when the number is rounded to the nearest thousand using rule of rounding numbers is
.
Rounding off numbers means adjusting a number simpler by adjusting it to its nearest place according to certain rules.
In rounding off numbers, the place value starts from tens place.
Rounding to the nearest whole number: Look at the digit immediately to the right of the decimal point. If it is 5 or greater, round the number up. If it is less than 5, round the number down.
When is rounded, 3 is at the thousand place. 3 is less than 5 , so the rest place will become 0.
Thus, the number will become when rounded to the nearest thousand.
The number 24,356 rounded to the nearest thousand will become

What is multiplication?
In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
Here, we have,
Amelia bought roast beef for $6.85 per pound.
Amelia bought 4 pounds of roast beef.
total cost = $6.85 * 4
=$27.40
hence, her total cost is $27.40.
