The answer would be
-63x^2y^3
Answer:
20%
Step-by-step explanation:
Find the difference of both prices.
150 - 120 = 30
Calculate the ratio of the decrease in price to the original price.
30/150 = 0.2
Multiply the decimal by 100 to get your percentage.
0.2(100) = 20
Answer:
it was discounted by $227.85
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let the base is x, then the legs are 2x each.
<u>The perimeter is:</u>
- x + 2x*2 = 50
- 5x = 50
- x = 10
The base is 10 cm and legs are 20 cm each.
The function we have is:

This is a linear function.
We can find the slope (the rate of change) of this function, by comparing it to the general slope-intercept equation:

Where m is the slope (rate of change) and b is the y-intercept of the line.
By comparison, we see that m an b are:

Since we are asked for the value of the rate of change, the answer is the value of m:

which is option A.
