Answer: the y intercept is -5
You can use the slope intercept form to find the answer. Aka y = mx + b
In this equation m is equal to the slope and b is equal to the y-intercept.
We already know the slope, 4. And we have two different point we can choose from. I’ll show how to solve with the first (1,-1) point.
136.4559 or 136.50 rounded.
Find the circumference of the hole. Then multiply the price of the irrigation system by the amount of ft needed.
Answer: $142.5
Step-by-step explanation: If the price is being marked up by 50%, you take 50% or half of the original price of $95, which is 47.5, and add it to your original price.
95 + 47.5 = 142.5
Set up the proportion of $ on one side and percents on other. You can put x for the retail value of the hat and 16 on the bottom. Then on the other side put the percentage of the added markup plus 100% which is the original price on the top over 100%. It should be something like x/16 = 155/100. The cross multiply. (x)(100) = 100x and (16)(155) = 2480. Then divide 2480 by 100 to isolate the x. Your final answer will be x = 24.80 which is the retail price.
