Answer:277
Step-by-step explanation:
For this problem, you will have to use PEMDAS (Parentheses) (Exponents) (Multiplication/Division) (Addition/Subtraction)
First of all, you will want to solve for the values inside the parentheses first
40 <span>÷ 1+3-(21)+7-5 Now check for anything that includes multiplication/division and do that
40+3-21+7-5 All you have left now is addition and subtraction. It must go from left to right, therefore if addition is first, do addition, if subtraction is first, then do subtraction.
Final answer = 24</span>
1/2 z = -3/4 + 1/4 z
1/2 z - 1/4 z = -3/4
1/4 z = -3/4
z = (-3/4)/(1/4)
z = -3/4 x 4/1
z = -3
Explanation:
To answer a question like this, refer to the definitions of the functions:
(f-g)(200) is ...
... the difference between the amount of money a cell phone screen is being sold for and the cost of production, when 200 screens are being manufactured.
__
The numerical value of (f-g)(200) is ...
f(200) -g(200) = (3·200 +5000) -(20·200 -400) = 5600 -3600
(f-g)(200) = 2000
