Answer: A. 1 pound of cabbage will cost 40 cents. B. (10,4) means that 10 pounds of cabbage will cost 4 dollars.
Step-by-step explanation:
If it is proportional that means the y value divided by the x value will give you a constant slope.
So using that use the coordinates (5,2) to find the cost of 1 pound of cabbage.
2/5 = 0.4
so you could write the equation y= 0.4x where x is the number of pound.
Part A: y= 0.4(1)
y= $0.40 which means one pound of cabbage will cost 40 cents.
Part B. (10,4) in this case it will means that for 10 pounds of cabbage it will cost $4.
Plot it into the equation and find out
in the coordinates (10,4) 4 is the y and 10 is the x
4= 0.4(10)
4= 4
Which means it true that 10 pounds of cabbage will cost 4 dollars.
4y(3y + 9)
12y + 36
36 ÷ 12=x=3
Ok, so we need to take 60 x 60. That gives us 3600, which is the amount of seconds in 60 minutes. Then we need to take 3600 x 24, to figure out the number of seconds in 24 hours (1 full day). That gives us 86,400. Finally, we take 86400 x 365, to determine how many seconds are in 1 full year (365 days). That gives us the answer of <span>31536000. Hope this helps!</span>
