Answer:
B. f(x) = 5(x/4) - 3 and g(x) = [4(x + 3)]/5
Step-by-step explanation:
In the figure attached, the question is shown (the order of the options are different).
To find the inverse of a function, first, replace x with g(x) and f(x) with x, as follows:
f(x) = 5(x/4) - 3
x = 5(g(x)/4) - 3
Next, isolate g(x), as follows:
x + 3 = 5(g(x)/4)
4(x + 3) = 5g(x)
[4(x + 3)]/5 = g(x)
The formula for the area of a triangle is:
where B is the base of the triangle and h is the height
It appears that the height of the triangle is 5 units (not quite 4.5) and the base is 10 units.
Multiply these to get 50, and divide by 2 to get 25.
The area of the triangle should be 25 u²
Hope this helps! :)
