The rate of change for this function is 1/2.
In order to find the rate of change, you use the slope equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (4 - 2)/(9 - 5)
m = 2/4
m = 1/2
Answer:
Step-by-step explanation:
Alex bought a new skate board at 20% discount. He paid $72. What percent of the original price did he pay?
Step 1
We find the original price
= Percent Discount × Original price =
= 20% × Original price = $72
= 0.2 × x = $72
x = $72/0.2
x = 360
The answer is A. You have to isolate the variable(f) by subtracting 0.2 from both side. When youve done that, the answer should be -3.2
