Answer:

4(x + 1) and 4(x - (-1))

Step-by-step explanation:

4(-1 + 1) = 4(0) = 0

(4 (-1) + 5) = -4 +5 = -1

4(-1 - 1) = 4(-2) = -8

(5 - 4(-1)) = 5 + 4 = 9

4(-1 - (-1)) = 4(0) = 0

4 (-1 + (-1)) = 4(-2) = 8

After driving half the way from the city to the Zoo, I passed a tour bus traveling at an average speed of 78 km/h in the opposit

enyata [817]

Answer:

The distance from the Zoo to the city is 80 km

Step-by-step explanation:

The given information are;

The speed of the tour bus = 78 km/h

The point of passing the tour bus = Half way between the city and the Zoo

The time taken after passing the tour bus when it was still 14 km from the city = 20 minutes = 20/60 hour = 1/3 hour

Therefore, we have that the distance covered by the tour bus in 1/3 hour = Time ×Speed = 1/3×78 = 26 km

The distance remaining for the tour bus to reach the city = 14 km

The total distance from the time of observation of the tour bus = Half the distance from the city to the Zoo

Also, the total distance from the time of observation of the tour bus = 26 km + 14 km = 40 km

∴ 40 km = Half the distance from the city to the Zoo

Which gives;

The distance from the Zoo to the city = 2 × 40 km = 80 km.
