Answer:
ok
Step-by-step explanation:
y=(-2/5)x + 6
y-6= (-2/5)x or y=(-2/5)x + 6
the perimeter is 35 and are is 40
37 mph
if he starts at 0 then goes to 20 then add another 35 which gives you 55mph then he slows down you decrease 11 which is 44 then decrease again 7 gives you 37mph
q
y=-3x/2
because gradient =-3/2
and u must use formula (y-y1) = m(x-x1)
