Answer:
Option A
Step-by-step explanation:
The given function is a linear function therefore rate of change of this function will be the slope of the given line.
Since this line passes through two points ( 0,1 ) and ( 0.5 0 )
the slope of the line =
slope =
= ( -2 )
Therfore, Option A will be the answer.
The rate of change of function is,
m = - 2
We have to given that,
A function is shown in figure.
Since, The rate of change of linear function is slope of line.
Here, Two points on the line are (1, - 1) and (0, 1)
Since, The equation of line passes through the points (1, - 1) and (0, 1)
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - (-1)) / (0 - 1)
m = 2 / - 1
m = - 2
So, The rate of change of function is,
m = - 2

Answer:
x=31
Step-by-step explanation:
x-10+x-10+x-10=63 (equation)
3x-30=63 (combine like terms)
3x=93 (combine like terms again)
x=31 (divide both sides by 3)
