Answer:
f^-1(x) = 1/5x + 1/5
Step-by-step explanation:
Switch the x and y values:
y = 5x - 1
x = 5y - 1
Put the equation back into y = form:
x = 5y - 1
x + 1 = 5y
1/5x + 1/5 = y
y = 1/5x + 1/5
f^-1(x) = 1/5x + 1/5
Answer:
Step-by-step explanation:
the formula of a circle is pie (3.14) times the radius squared.
so the answer is 1963.50
Answer:
Correct answer is : $220
Step-by-step explanation:
Here, cost price = $66
Let the selling price be $x.
According to the statement given in problem,
Selling price - cost price = 70% of selling price
i.e. x - 66 = 70% * x
x - 70x/100 = 66
30x / 100 = 66
x = 6600 / 30 = $220
i.e Selling price = $220
