Answer:
D)
Step-by-step explanation:
f(-3) = 2
f(0) = -5
[f(-3) - f(0)] ÷ -3-0
[2-(-5)] / -3
7/-3
Your problem is an example of a distance problem, so you muct know the formula to find the distance. To find the distance we simply multiply the rate by the time, or as you'll see more often, d = r t. That means to calculate distance traveled you need rate and time.
Take note, planes are traveling in opposite direction, which means 2000 miles will be the sum of the distances that the two planes have traveled.
D (Plane 1) + D(Plane 2). = 2000
Let t = time in minutes
560t + 500t = 2000
Solve for t. Take it ftom here.
2x-1=3/4x+9
2x-3/4x=9+1
1.25x=10
X= 8
Answer:
74
Step-by-step explanation:
74+73+71+73+73+74=438÷6=73
Answer:
$5028.4
Step-by-step explanation:
The expression for that investment will be 2500*(1.15)^t where t is in years, the value of the investment will be 2500*(1.15)^5=5028.4
