Answer:
The graph of the inverse function is the same that the graph of the original function
Step-by-step explanation:
step 1
Find the equation of the function in the graph
Let
f(x) ---> the function in the graph
we know that
Is a linear function
take the points (0,6) and (6,0)
<em>Find the slope of the linear function</em>
<em>Find the the equation of the linear function in slope intercept form</em>
we have
---> the y-intercept is given
substitute
step 2
Find the inverse of the function f(x)
Let
y=f(x)
<em>Exchange the variables (x for y and y for x)</em>
Isolate the variable y
Let
In this problem the graph of the inverse function is the same that the graph of the original function
Answer:
Divide the price by the number of months to find the monthly rate.
$237.36 ÷ 24 = $9.89 per month
$184.50 ÷ 18 = $10.25 per month

Step-by-step explanation:
Answer:
r = 31.2
Step-by-step explanation:
Δ ACE and Δ BCD are similar, thus the ratios of corresponding sides are equal, that is
= 
, substitute values
= 
( cross- multiply )
40r = 1248 ( divide both sides by 40 )
r = 31.2
Answer:
Minimum value of f(x) = -1.
Step-by-step explanation:
We convert it to vertex form:
x^2 - 6x + 8
= (x - 3)^2 - 9 + 8
= (x - 3)^2 - 1
The minimum value occurs when (x - 3)^2 = 0 because a square has a minimum value of zero ( it cannot be negative for real values of x).
So the function has a minimum value of -1.
Answer:
Step-by-step explanation:
Area of triangle = ½(12)(8) = 48 m²
Area of semicircle = ½π(4²) = 8π
Α = 48 + 8π m² ≈ 73.132741... m²
