Answer:

Step-by-step explanation:
Consider the real number y such that f ⁻¹(x) = y

We need to find y in order to determine the expression of f ⁻¹(x)
f(y) = x ⇔ -2y + 4 = x
⇔ 4 - x = 2y
⇔ y = (4 - x)/2

Answer:
0.13 cents
Step-by-step explanation:
1.99 / 15 = 0.1326, rounded is 0.13
Answer:
See IN set by step
Step-by-step explanation:
1.We choose a fish pond of radius 3 centered at (x, y) = (0, 3). The equation of the circle is ...
(x -0)^2 +(y -3)^2 = 3^2
x^2 +(y -3)^2 = 9
At this location it is easy to draw a radius along the y-axis to a point of tangency at the origin. That radius is a vertical line, so the tangent line will be perpendicular--a horizontal line.
A horizontal line through the origin has equation y = 0, and its point of intersection with this circle is (0, 0).

Comment on the question
You haven't elaborated on what the lesson discussed, so we have no idea what steps you want included.
I could not answer 2 and 3 but maybe if i get it i will edit this paper and add it in.
Answer:
Your answer is -80
Step-by-step explanation:
Hope this helps! :D
You got the top part right, but you are missing the bottom it would actually be -56/5 or -56 over 5.
