Step-by-step explanation:

the average rate of change in the interval is the slope

(-1,4) (2,0)

slope = (y2-y1)/(x2-x1)

slope = (0-4)/(2--1)

slope = (-4)/(2+1)

slope = (-4/3

Answer:

First, you want to solve for the equation for this problem, would be:

0.05N + 0.10D = 20.50

While N = The amount of nickels, and D = The amount of dimes.

Since N = 164, and D = 123. It would add up to 287 coins. 164 + 123 = 287.

Now that you have the number for those two variables, solve the equation for when N = 164, and D = 123.

0.05N + 0.10D = 20.50

0.05(164) + 0.10(123) = 20.50

8.2 + 12.3 = 20.50

20.50 = 20.50

So, there is 164 nickels, and 123 dimes for your answer.

I hope this helps!

Sergio [31]

Since both trains in total weigh 360 tons and train A weighs more than train be, it means that train B is the rest of the weight when you subtract train A from the total amount. Difference means subtraction so just solve this: 360-272 to get train B and you already know that train A is 272 tons. Please mark branliest!
