Answer:
Domain of the given function is all real numbers and the range of the function all real numbers.
Step-by-step explanation:
The given function is
.... (1)
The slope intercept form of a line function is
.... (2)
Where, m is slope and b is y-intercept.
From (1) and (2), we get
It means the slope of the line is -5 and y-intercept is 4.
Draw a line with slope -5 and y-intercept 4 on a coordinate plane as show below.
Domain is the set of inputs and range is the set of outputs.
The function is defined for all values of x. So, the domain of the function is all real numbers.
The value of function can be any real number. So, the range of the function is all real numbers.
Therefore, the domain of the given function is all real numbers and the range of the function all real numbers.
Answer:
<em>1.1n</em>
<em>0.6p</em>
<em>0.3b</em>
Step-by-step explanation:
<u>Simplifying Like terms</u>
Like or similar terms are those who have the same letters raised to the same power. For example, 5ab, -6ba, 0.6ab are like terms.
Terms like 5xy, -6xz, are not similar because they have different letters of powers.
The terms 1.6n-0.5n are similar and they can be simplified by operating their coefficients: 1.6-0.5=1.1. Thus
1.6n - 0.5n = 1.1n
Similarly, we can simplify 0.9p-0.3p. Operating 0.9-0.3=0.6 gives the result:
0.9p - 0.3p = 0.6p
Finally:
b - 0.7b = (1 - 0.7)b = 0.3b
Results:
1.1n
0.6p
0.3b
