Answer:
k=3
Step-by-step explanation:
Answer:
9. y=9h+4
10. y=5r+10
11. y=4x+8
12. y=4n+9
Step-by-step explanation:
9. He gets 9 dollars per hour (h), and 4 dollars extra for gas.
So 9 dollars per hour plus 4 dollars for the gas
y=9h+4
10. Roses (r) are selling for 5 dollars each and there is a delivery fee of 10 dollars.
So 5 dollars per rose plus 10 dollar fee
y=5r+10
11. The tree increases by 4 feet per year (x), and it is already 8 feet tall.
So 4 feet per year plus 8 feet
y=4x+8
12. Each trophy (n) weighs 4 kilograms, and the box itself weighs 9 kilograms.
So 4 kilograms per trophy plus 9 kilograms for the box.
y=4n+9
Differentiating both sides of
with respect to 
yields
At the point (3, 4) (so 
and 
), the tangent line has slope
Then the tangent line to (3, 4) has equation
the scale is x4
because 10x4=40
11x4=44
18x4=72
you multiply by 4 on all of them
Pi because pi can be any number, it could be 2 or 1299 or even 1000000 so that is why the answer to your question Nicolas is pi.
