Answer:
y+2=3(x+1)
Step-by-step explanation:
y-(-2)=3(x-(-1))
y+2=3(x+1)
the rate given is 345 ft/min
this means within 1 min distance is - 345 ft
we have to convert this speed to ft/h
1 hour is equivalent to 60 minutes
so if 60 minutes equals 1 hour
1 minute is equal to - 1/60 hr
so the distance within 1 minute is - 345 ft
since 1 min = 1/60 hr
distance within 1/60 hour = 345 ft
therefore distance in 1 hour = 
answer is 20 700 ft/h
This is the image the points form, if you know your quadrilaterals, this should make it easier to picture and label. Need any further explanation?
Answer:
Step-by-step explanation:
“y varies directly as x”
y = kx
Plug in (4, 1.25) and solve for k:
1.25 = 4k
k = 1.25/4 = 0.3125
The equation becomes
y = 0.3125x
4(x-7) is what i got for my answer
