The original answer is 5.2186. After you round, your answer should become 5.22
The graph of each function is a sloping straight line, and
they both have the same slope (they're parallel).
In order to make the graph of f(x) coincide with (lie on top of) the
graph of g(x), you have to slide the graph of f(x) down 13 units.
You can look at their y-intercepts: The intercept of f(x) is +9 ,
and the intercept of g(x) is -4 . So they cross the y-axis at
two points that are 13 units apart. Since the lines are parallel,
they're 13 units apart everywhere. And the graph of g(x) is always the lower one.
Step-by-step explanation:
5×10³) × (9×10^7)
= 45 × 10^10
= 4.5 × 10¹¹
