y - 5 = -7(x - 6)
the equation of a line in ' point- slope form ' is
y - b = m(x - a )
where m is the slope and (a, b) a point on the line
here m = - 7 and (a, b ) = (6, 5 )
y - 5 = - 7(x - 6 ) ← in point- slope form
I’m not 100% shure but I think it’s 5 or C.
T=time
d=st
r=train speed
p=plane speed
<span>160=rt
</span><span>720=pt
speed of plan is 20kmph less than 5 times speed of train
p=5r-20
we notice that 160 times 4.5=720
times first equaton by 4.5
720=4.5rt
720=pt
set equal
4.5rt=pt
divide both sides by t
4.5r=p
sub </span><span>p=5r-20 for p
4.5r=5r-20
minus 4.5r from both sides
0=0.5r-20
add 20 to both sides
20=0.5r
times 2 both sides
40=r
sub back</span><span>
p=5r-20
p=5(40)-20
p=200-20
p=180
plane is 180kmph
train is 40kmph
