Step-by-step explanation:
Answer:
27 minutes
Step-by-step explanation:
Given that:
It takes 16 minutes for 9 people to paint 8 walls.
i.e
16 minutes ------------ 9 people ---------- 8 walls
How many minutes does it take 4 people to paint 6 walls?
let the number of minutes be (m). NOW;
(m) minutes ------------ 4 people ------------ 6 walls
If it takes 16 minutes for 9 people to paint 8 walls.
∴ For 1 person to paint 8 walls; it will take 16 minutes × 9 = 144 minutes
So, to determine the number of minutes it will take 1 person to paint 6 walls; we have;
6 walls =
6 walls × 144 minutes = 8 walls × (m)
(m) =
m = 108 minutes
So, it will take 108 minutes for one person to paint 6 walls.
For 4 people now; we have
m =
m= 27 minutes
∴ it will take 27 minutes for 4 people to paint 6 walls
To make this easier, first draw or imagine a vertical line at x=2
Find where the vertical line and the graph intersects.
Draw or imagine that point of intersection.
Now, draw or imagine a horizontal line that goes through the point of intersection.
That horizontal line tells us the the value of the function by passing through that mark that says "-2"
The function's value at x=2 is -2.
Have an awesome day! :)
