Answer:

The function is increasing from x = 0 to x = 1.

Step-by-step explanation:

A <u>function</u> is increasing when the <u>y-value increases</u> as the <u>x-value increases</u>.

A <u>function</u> is decreasing when the <u>y-value decreases</u> as the <u>x-value increases</u>.

From x = -2 to x = -1 the function is decreasing as the y-value decreases as the x-value increases:  

  • x-value -2 to -1 → increase
  • y-value 2 to 0 → decrease

From x = -1 to x = 0 the function is increasing as the y-value increases as the x-value increase:  

  • x-value -1 to 0 → increase
  • y-value 0 to 2 → increase

From x = 0 to x = 1 the function is increasing as the y-value increases as the x-value increase:  

  • x-value 0 to 1 → increase
  • y-value 2 to 8 → increase

If the original bill is $22.50, what will be the final bill after a 15% tip is paid? round to the nearest cent
Studentka2010 [4]
For this case what you should do is take 15% of 22.50 and add it to the original price. We have then:
 ((15) / (100)) * (22.50) = 3.375
 Then, we add to the original price:
 22.50 + 3.375 = 25.875
 round to the nearest cent
 25.88

 C.$25.88

I will make u the BRAINLIEST pls answer my question and explain!!!
Whitepunk [10]
The azalea is located at point (4, -4). You have already plotted the hydrangea at (4, 6). If you count up the number of squares from the hydrangea to the azalea plant, you will get a distance of 10. 

Since the problem tells you the length of each square is 1 ft, then you know that the distance between the two plants is 10 squares * 1 ft/square = 10ft.
