Answer:
y=18 when x=6 k = 3
Step-by-step explanation:
y varies directly as x
y= kx,where k is constant
there,making k the subject of the formulae
k=y/x
k=18/6
k=3
3 because 7/12 is greater then 6/12 (which is half) so you would round up to 3.
The answer might be 12 feet, I don’t know that well I suck at math
Answer:
slope = - 50
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (4, 2400) and (x₂, y₂ ) = (12, 2000) ← 2 points on the line
m = = = - 50
The difference is 7 fours
