Answer:
f(x) = -5x + 4
Domain refers to the values of x that would result to a defined value of y. Since the given f(x) is a linear function, then all the values of x would give a corresponding value of y. So, the domain of f(x)=-5x+4 are all real numbers.
Or, plot the given equation to check.
The graph of f(x)=-5x+4 is shown below.
Since the graph is a straight line and can be extended continuously on both ends, this indicates that every values of x, there is a corresponding value of y.
Hence, the domain of the given function are all real numbers.Step-by-step explanation:
22 houses can be cleaned in 11 hours.
Step-by-step explanation:
It is given that;
6 hours = 12 houses cleaned
1 hour =
1 hour = 2 houses cleaned
In 1 hour, 2 houses can be cleaned, therefore,
11 hours = Time*houses cleaned in one hour
11 hours = 11*2 =22 houses cleaned
22 houses can be cleaned in 11 hours.

Answer:
slope=x
Step-by-step explanation:
The slope of a line that is perpendicular to another will have the negative reipricol of the first slope. For example:
-1/3 = 3
-6 = 1/6
4= -1/4
The equation is written in slope-intercept form:
y=mx+b
M is the slope. In the given equation, the slope is -x, which can also be written as -1x. The negative reipricol of -1x is 1x, or just x.
The slope of the perpendicular line is x.
