Answer:

Step-by-step explanation:
The rate of change of the function f(x) from point
to point
can be calculated using formula

Given

From the graph of the function

So, the rate of change is

9,18,27,36,45,54,63,72,81,90,99
Answer:
y = 384
Step-by-step explanation:
Find an equation that fits the graph
When the value varies directly, y = kx.
Find k by substituting x and y in the equation
y = kx
48 = 18k
k = 48/18
k = 8/3
To find the value of y when x= 144 by substituting x for 144
y = 8/3 x
y = 8/3 (144)
y = 1152/3
y = 384
y is 384 when x is 144.
Since a percent is out of 100 then writing a percent in fraction form would be whatever the percent is over 100. so if youre trying to figure out what 70 out of 250 is in percent for you would write it like this:
