Answer:
The percentage decrease of the shirt's price is 15%.
Step-by-step explanation:
1) divide 36.15 by 30.75
30.75/36.15=0.85
2) Multiply 0.85 by 100 to find the percentage between the original and sale costs of the shirt
0.85(100)= 85%
3) Find the difference between 85% and 100% to find the percentage difference
100%-85%= 15%.
Therefore, the answer is 15%.
Hope this helps!
Answer:
X/-5
Step-by-step explanation:
(55 + 150 + 325 + 510 + 780 + 990) - (40 + 150 + 300 + 500 + 800 + 1000) = 2810 - 1790 = 20
Answer:
x = 15
Step-by-step explanation:
I have this all put under a photo. Let me know if you need any explanation
The average rate of change from x = -9 to x = -1 of the graph of the given function is 0.
We know that the rate of change of a function is nothing but the slope of the line.
The slope of the line is given by;
Slope = Change in y-coordinate / change in x-coordinate
We are given the graph of a function.
We need to find the average rate of change from x = -9 to x = -1.
Let us find the value of y or f(x) for the given value of x.
For x = -9, y = 2
For x = -1, y = 2.
Put the values of x and y in the slope formula, we will get;
Slope = (2 - 2) / (- 1 - (-9)) = 0
So, the rate of change of function is 0.
Thus, the average rate of change from x = -9 to x = -1 of the graph of the given function is 0.
