-2x+4
Step-by-step explanation:
2(x+2) - 4x
Distribute
2x+4 - 4x
Combine like terms
-2x+4
Answer:
x=-7/3
Step-by-step explanation:
-6x-7=7
-6x=7+7
x=-14/6
x=-7/3 or in mixed fraction
x=-2 1/3
Percent error=|

| times 100
(note the || is absolute value, means that whatever the result is inside, it is made positive)
predicted value=261
actual value=293
subsitute
percent error=|

| times 100
so using pemdas
do parenthasees first

|
|-0.12|
absolute value
0.1226
time 100
0.1226 times 100=12.26
answer is 12.26%
answer is B
Just multiply 44 times 3 the you should get your answer
Step-by-step explanation:
(a)
the cost function is
C(x) = 300 + 20x
(b)
the revenue function is
R(x) = 35x
(e)
the profit function
P(x) = R(x) - C(x) = 35x - 300 - 20x = 15x - 300
(d)
break-even is the point where C(x) and R(x) are equal :
C(x) = R(x)
300 + 20x = 35x
300 = 15x
x = 300/15 = 20
so, the break-even is only achieved when 20 units are produced and sold. and with more than 20 sold units the business would then make a profit.
per our restrictions only max. 19 units can be sold, so, the business will always be in the negative numbers (unless they cheat and sell virtual units that were never produced).
therefore, the product should not be produced at all.
