Answer: (g-f)(x)=-4x
Explanation: According to the graph, line created by function f(x) passes through the points (1,-3) and (0,0) and similarly, line created by the function passes through the points (1,1) and (0,0).
Thus, we can find the equation of the lines with help of formula 
× 
so, equation of line created by function f(x)
y+3=
×(x-1)
y+3=
×(x-1)
y+3=-3x+3
y=-3x thus function f(x)=-3x
similarly, equation of line created by function g(x)
y=x thus function g(x)=x
Now, we have to find out, (g-f) (x)= g(x)-f(x)= -3x-x= -4x

Answer:
455
Step-by-step explanation:
The decrease was 30% of 650, or ...
0.30 · 650 = 195
So, the population this year is ...
650 -195 = 455
Answer:
5x + y - 4 = 0
Step-by-step explanation:
When we are given two points and are asked to find the equation of the line we use the two - point form.
Two - point form: 
.
where: 
and 
are the two points on the line.
Given the two points are: (5,21) and (-5,-29).
Substituting in the two point form:
⇒ 
⇒ 5x + y - 4 = 0
The answer is 1 bc the solution is (1,-3)
