It’s D bc Dt= 15x3 and it’s not that hard to solve
Answer:
-6+12t
Step-by-step explanation:
Answer: 2526 dollars
=============================
Work Shown:
Plug n = 400,000 into the function and simplify
f(n) = 939 + 5.29*(n-100,000)/(1,000)
f(400,000) = 939 + 5.29*(400,000-100,000)/(1,000)
f(400,000) = 939 + 5.29*(300,000)/(1,000)
f(400,000) = 939 + 5.29*(300)
f(400,000) = 939 + 1,587
f(400,000) = 2526
To get the slope you need to solve for y:
12x+3y=-17
Subtract 12x from both sides:
3y=-12x-17
Divide everything by 3:
y=-4x-17/3
The slope is -4.
