$\bf \cfrac{zz}{4} + 5\geqslant 5.5\implies \stackrel{\textit{subtracting 5 from both sides}}{\cfrac{zz}{4}\geqslant 0.5}\implies \stackrel{\textit{multiplying both sides by 4}}{zz \geqslant 2}$

What is the intial value and rate of change in this graph. please explain step by step!!!!!

WARRIOR [948]

The initial value of the graph is where $x = 0$ . Thus, in this case, the initial value is 12.

The rate of change of the graph is essentially the slope of the graph. In this case, we can use the slope formula:

$\dfrac{y_2 - y_1}{x_2 - x_1}$

$(x_1, y_1)$ and $(x_2, y_2)$ are points on the graph

Let's use two points from the chart to find the slope:

$m = \dfrac{30 - 21}{2 - 1} = 9$

In this case, the rate of change of the graph is 9.
