Answer:
80/3 or 26 2/3
Step-by-step explanation:
-2 + y = 9 (subtract y from both sides)
-2 = 9 - y (subtract 9 from both sides)
-2 - 9 = y (multiply both sides by -1)
2 + 9 = y (simplify)
11 = y (substitute)
3x - 7 (11) = 3 (multiply)
3x - 77 = 3 (subtract 3 from both sides)
3x - 80 = 0 (subtract 3x from both sides)
-80 = -3x (multiply both sides by -1)
80 = 3x (divide both sides by 3)
80/3 = x (simplify if needed)
26 2/3 = x
Answer:
If the company produce and sell 'x' no. of thing-a-ma-bob , then
C(x) = $ (8809 + 2.05x)
R(x) = $ 4.92x
To make a profit the company must produce and sell at least 3070 thing-a-ma-bobs.
Step-by-step explanation:
If the company produces and sells "x" no. of thing-a-ma-bob, then,
the cost function is given by,
C(x) = $ (8809 + 2.05x) ------------------------(1)
The revenue function is given by,
R(x) = $ 4.92x -------------------------------------(2)
If C(x) = R(x), then,
4.92x = 8809 + 2.05x
⇒ 2.87x = 8809
⇒ x = 
⇒ x
3069.34
So, to make a profit the company must produce and sell at least 3070 thing-a-ma-bobs.
2006 Pop. = 47.9 million
Expected decrease = 4.8% = .048
Expected population = 47.9 million (1- .048) = 45.60 million
If the snowboarder descends 12000 feet hill in 3 minutes, then in one minute he'll descend 12000 / 3 = 4000 feet. So the mean change in elevation per minute is 4000 feet per minute.
