Answer:
10 + 0.05m; m = 350 minutes
Bob's phone bill will be $27.50
Step-by-step explanation:
$10 + ($0.05 x 350 minutes) = $27.50
F(x) = (1/2)x + 4
Plug y in for f(x).
y = (1/2)x + 4
Swap x and y.
x = (1/2)y + 4
Solve the equation for y =.
Subtract 4 from both sides.
x - 4 = (1/2)y
Multiply each term 2.
2x - 8 = y
Plug f^-1(x) in for y.
f^-1(x) = 2x - 8
f^-1(4) = 2(4) - 8
f^-1(4) = 0
-3/6 -5/7
-21/42 - 30/42
-51/42
- 51/42 = - 1 9/42

Answer:
Area 1 is the best option
Step-by-step explanation:
Given Data:
Area 1 = 0.75 dam square
Price = €11,620
Area 2 = 0.009 ha
at €193,500
Area 3 = 0.84a
at €68,900
Where ha ( hectare )
a ( area )
Solution
First we convert all areas to square meter ( m² )
Area 1 = 100 * 0.75 dam square
= 75m²
Cost of area 1/ square meter
= €11,620 / 75m²
= €154.93 / square meter
Area 2 = 0.009 ha * 10,000
= 90m²
Cost of area 2 / square meter
= €193,500 / 90m²
= €2,150 / square meter
Area 3 = 0.84a * 100
= 84m²
= Cost of area 3 / square meter
= €68,900 / 84m²
= €820.23 / square meter
