Answer:
An inverse function is a function that undoes the action of the another function. A function g is the inverse of a function f if whenever y=f(x) then x=g(y). In other words, applying f and then g is the same thing as doing nothing. We can write this in terms of the composition of f and g as g(f(x))=x.
Step-by-step explanation:
The inverse function returns the original value for which a function gave the output. ... A function that consists of its inverse fetches the original value.
Example : f(x) = 2x + 5 = y. Then, g(y) = (y-5)/2 = x is the inverse of f(x).
Answer:
Scott will have to do 44 practices
Step-by-step explanation:
Let X be the number of yards per practice.
Let P = number of practice Scott needs to do.
Multiply 20 yards by 4 sprints
X = 20yards × 4 sprints = 80 yards
Number of yards he had to sprint per practice will be:
1 mile = 1760 yards
Converting from miles to yards
X = 1760 × 2 miles = 3520 yards
Number of practice,P Scott need to do = (3520/80)yards
Number of Practice,P = 44

The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.
<h3>What is a mathematical proof?</h3>
Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.
<h3>What is the proof that WV = VR?</h3>
Reason: This is given. The image is a parallelogram.
- Hence, ∠PSR = ∠WVP
Reason: Alternate angles formed by two parallel lines crossing each other
Hence, SV = PVReason: This is given by the annotation on the image
- Reason: They are formed by two parallel lines crossing each other.
Therefore if ΔSVR ≅ PVW;
Then WV = VR.

Answer:
AC = 25.5 or 1.5
Step-by-step explanation:
If they are on a line and they are in the order ABC
AB + BC = AC
12+13.5 = AC
25.5 = AC
If they are on a line and they are in the order CAB
CA + AB = BC
AC + 12 =13.5
AC = 13.5 -12
AC = 1.5
If they are on a line and they are in the order ACB
That would mean that AB is greater than BC and that is not the case
