6 days
Y= 107-8x
Y=83-4x
You can use substitution
83-4X= 107-8x
Bring 8X
Over to the left
83+ 4x=107
Subtract 83
4x= 24
X=6
Or put in calculator and go 2nd graph you see table and on 6 day they both have $59
Answer:
Step-by-step explanation:
P1 = (3.5,5) in the form (x1,y1)
P2 = (3.5,-12) in the form (x2,y2)
dist = sqrt[ (x2 - x1)^2 + (y2-y1)^2 ]
dist = sqrt[ (3.5-3.5)^2 + (-12-5)^2 ]
dist = sqrt [ 0 -17^2]
dist = 17
