Answer:
4x² - x - 1
Step-by-step explanation:
(f - g)(x) = f(x) - g(x) , thus
f(x) - g(x)
= 4x² - (x + 1) ← distribute parenthesis by - 1
= 4x² - x - 1
Answer:
Step-by-step explanation:
If you’re looking for x it would be -4/3
Answer:
4.8 hours
Step-by-step explanation:
First, divide the distance by time to get velocity.
S = D/T
S = 360/4
S = 90 mph
Then, subtract 15 from 90 to get the new speed.
90 - 15 = 75
Lastly divide the distance by the new speed to get time.
T = D/S
T = 360/75
T = 4.8
Therefore, it would take the car 4.8 hours to travel 360 miles at 75 miles per hour.
Answer:
220
This should be correct since you are multiplying by 2
