I don't know, backflips? I'm just naming a random trick.
The true statement about the graph of f(x) is 
The graph of f(x) is a straight line that passes through the points (-5,0) and (0,3).
Start by calculating the slope (m)

So, we have:

Simplify

The equation of the line is then calculated as:

This gives

Open bracket

Express y as a function of x

Hence, the true statement about the graph of f(x) is

Answer:
5
Explanation:
Word problem.
First statememt
n/2 - 4 = -6. ....... (1)
Second statement.
3n + 7 = x. ....... (2)
From (1)
n/2 - 4 = -6.
n/2 = -6 +4
n/2 = -2
n= -4
Put n into (2).
3n + 7 = x
3(-4) +7 = x
x= -12 +7 = -5
The answer is -5.
Explanation:
Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction. The reactivity of metal is determined by a series known as reactivity series. The metals lying above in the series are more reactive than the metals which lie below in the series
