Answer:
The answer is, A. it is constant
Step-by-step explanation:
Between the x values 4 and 8 the line does not decrease or increase. It stays in a straight line causing it to be constant.
Answer:
252
Explanation:
An equation to represent the situation is:
17.5% * 1440
convert 17.5% into a decimal:
0.175
and then solve:
0.175 * 1440 = 252
Option A: The rate of change of Function R is less than the rate of change of Function S because
is true.
Explanation:
The function 
The equation for function R can be determined using the slope formula,

The y-intercept is the value of y, when x = 0.
Thus, the y-intercept is
.
To determine the slope, let us substitute the coordinates
and
.
Because, the points on the straight line have the same slope.
Thus, we have,

Thus,
and 
Let us substitute these values in the formula
, we get,

Hence, the equation of R is 
The equation of S is 
Comparing the slope of these two equations, we have,

This means that the slope of R is less than the slope of S.
Hence, The rate of change of Function R is less than the rate of change of Function S because 
Thus, Option A is true.
18x+6=3(6x+1)
18x-18x=3-6
0x=-3
