The answer is A. Subtract the five on both sides and you end up with A :)
Answer:
A unit rate is the rate of change in a relationship where the rate is per 1.
The rate of change is the ratio between the x and y (or input and output) values in a relationship. Another term for the rate of change for proportional relationships is the constant of proportionality.
If the rate of change is yx, then so is the constant of proportionality. To simplify things, we set yx=k, where k represents the constant of proportionality.
If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation. In a direct variation equation, y varies directly with x. When x increases or decreases, y also increases or decreases by the same proportion.
To find y in a direct variation equation, multiply x by the constant of proportionality, k.
For example: Given the relationship y=7x, the constant of proportionality k=7, so if x=3, then y=3×7 or 21.
Given the same relationship, if x=7, then y=7×7, or 49.

Step-by-step explanation:
This equals the the area of white part / area of the entire dartboard
area of the entire board = pi * 6^2 = 36pi
area of white part = 36pi - 2^2*pi = 32pi
do required probability = 32pi / 36pi = 0.889 or 88.9 % (to nearest tenth)
or as a fraction it is 8/9
Answer:
Option 4
Step-by-step explanation:
Given function is,
Steps to get the inverse of the given function,
Step 1,
Convert the function into equation,
Step 2,
Interchange the variables 'x' and 'y',
Step 3,
Solve the equation for the value of y,
Step 4,
Convert the equation into inverse function,
For x-intercepts,
Substitute y = 0,
Therefore, x-intercept of the inverse function is 
.
Option 4 will be the answer.
