Answer:
4 sufficient to determine GRN and WZK are not congruent
Given:
The equation is

Where, y is earnings for working in dollars and cents and x is the number of working hours.
To find:
The rate of change.
Solution:
The slope intercept form of a linear function is
...(i)
Where, m is the slope and b is the y-intercept.
We have,
...(ii)
On comparing (i) and (ii), we get

Therefore, the rate of change is 21.2 dollar and cents per hour.
Answer:
Axis of symmetry for the functions f(x) and h(x) are x = 4 and x = -2 respectively.
Step-by-step explanation:
Function f(x) = -2(x - 4)² + 2
Vertex of the graph → (4, 2)
Since line of symmetry of the graph is defined by the x-coordinate of the vertex.
Therefore, x = 4 will be the line of symmetry of the function 'f'.
Second function 'h' has been given in the graph.
Vertex of the function from the graph → (-2, 2)
Therefore, line of symmetry will be x = -2
Always remember rise over run, used to see what slopes are. In this case, rise over run would be -3/2, because the line is negative.
Answer:
x=-6

I hope this helps, I write it on a sheet because I don't have pencils and notebook now ^_^
