A group of mountain climbers begin an expedition with 270 pounds of food. They plan to eat a total of 15 pounds of food per day. Which linear equation in slope intercept form represents this scenario?

A. y = - 15 + 270
B. y = -270x + 15
C. y = 270x - 15
D. y = 15x + 270

I think it is D, but just in case.

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.

Aquantity with an initial value of 3900 decays exponentially at a rate of 35% every hour. what is the value of the quantity after 0.5 days, to the nearest hundredth?
