The function f(x) is a function of the variable x.
To solve the function for x = 30, just plug in 30 for x.
14 - 0.5(30) = -1
f(30) = -1
To solve the food one you need to first multiply the pounds of peaches by the amount per pound (1.75 * 18.4) then when you have the total of that, add 2.89 for the price of the pineapple. Once that is complete you should have a total amount for all of the food, next you just divide that number by 4 and you'll have the amount of money each person paid.
As for the other question, to solve it all you need to do is add the total amount of pounds of trash team A has collected for both week 1, 2 and 3, then multiply it by 3 and you'll have your answer.
Answer: y + 1 = 2(x-6)
Step-by-step explanation:
Point Slope Form is y-y₁=m(x-x₁), and all you have to so is substitute in the values that you were given. So, the slope is 2, so you substitute that value in for m. Then, you substitute 6 in for x₁ (because 6 is the x value of the coordinate you were given) and you substitute -1 for y₁ (and it becomes positive because two negatives make a positive)
