A car moving at a constant speed passed a timing device at t=0. After 9 seconds, the car has traveled 837 ft. Write a linear fu nction rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device.
1 answer:
Answer:
at t=0 the car has moved 0 feet, also you know it has a constant speed so you get the points:
P1:(0,0) therefore you know b, the y-intercept=0
P2:(8,840)
insert P2 into y=mx+b
840=8m+0
840/8=m
105=m
so the result is:
y=105x=105t=f(t)=d

Answer:
given that, y=2×7
y=14
and
x+y=5
x+14=5
x=5-14
x=9
x not equal to 5
