Answer:
x = 8
Step-by-step explanation:
By first drawing a photo, pasted below, you can plot your points. Then use the formula:
a/c = b/d to plan out your equation
3x - 8/x = 16/x
Cross multiply so you then have:
16x = 3x^2 - 8x
24x = 3x^2
8 = x
To check:
3(8) - 8 = 16
24 - 8 = 16
16 = 16
Yes, but not without cutting some of the tiles into smaller pieces.
The length of the area is 8-ft. That's (2 and 2/3) tiles long.
The width of the area is 4-ft. That's (1 and 1/3) tiles wide.
So you can't just put down rows and columns of whole tiles
and cover the whole area.
______________________________________
Another way to look at it:
-- The area of the whole big plot is (8 x 4) = 32 square feet.
-- Each tile covers (3 x 3) = 9 square feet.
-- You can't cover 32 square feet with 9-square-feet pieces.
Either you have to cut something off, or else you have to let
something hang outside of the lines.
Answer:
Increasing on the interval(s) 
Decreasing on the interval(s) 
Step-by-step explanation:
Anytime the graph is going upward, the function is increasing. However, anytime the graph goes down, the function is decreasing. Look at the image below for further reference. Also, when the function is increasing, the slope is positive, and when the function is decreasing the slope is negative.
The increasing interval of the graph is -3
The decreasing interval of the graph is 0.5
Since the values are in the middle of the interval, it automatically becomes the answer.
First is 7 second is 8 third is 3
