1) find the corresponding y values for when x = 0 and when x = 4,
when x = 0, y = 4
when x = 4, y = 4
the coordinates are (0,4) and (4,4)
2) to calculate the average rate of change, find the slope of the two points:
(0,4) (4,4)
(change in y) 4 - 4 = 0
(change in x) 4 - 0 = 4
0/4 = 0
the average rate of change is 0!
Answer:
Step-by-step explanation:
The given ratio is
9 is the common factor of 18 and 27
divide numerator and denominator by 9
hence is proportion with
25% = 1/4
So to get the unknown number, multiply 9 by 4:
9 × 4 = 36
