Hello,
y+1/2=3(x-2)
or y=3x-13/2
Answer:
41428.57
Step-by-step explanation:
Average rate of change=(y2-y1)/(x2-x1)
(840,000-550000)/(11-4)
=41428.57
The inverse of the equation y = x² - 4, x≤ 0 is 
<h3>How to determine the inverse of the equation?</h3>
The equation is given as:
y = x² - 4, x≤ 0
Swap the x and y values
x = y² - 4
Add 4 to both sides
y² = x + 4
Take the square root of both sides

Hence, the inverse of the equation y = x² - 4, x≤ 0 is
