Answer:
See below.
Step-by-step explanation:
D(t) = 3260 - 55t
The function that shows their distance from home as a function of time shows that they started 3260 miles from home and are driving at 55 miles per hour.
part a:
D(12) = 3260 55(12)
D(12) = 3260 - 660
D(12) = 2600
Interpretation: After 12 hours of driving home, they are 2600 miles from home.
part b:
D(t) = 2490
3260 - 55t = 2490
-55t = -770
t = 14
Interpretation: When they are 2490 miles from home, they have driven for 14 hours.
Answer:(x+1)(x+14)
Step-by-step explanation:
Answer:
y = 5 -
73/8 = -0.443 or y = 5 +
73/8 = 1.693
Step-by-step explanation:
step 1: Equation
step 2: Trying to factor by splitting the middle term
30%,
1-5=20%
so 50%-20%= 30%
