Answer:
C. 0
Step-by-step explanation:
Since we are finding f(-4), we use the first function since -4 is less than -2.
f(-4) = (-4) + 4 = 0
Therefore, the answer is C.

Answer:
12.6 km
Step-by-step explanation:
Two people going towards each other meet at the time:
t = d/(v1+v2)
where:
- d is the distance between the people (here, the distance between the villages)
- v1 and v2 are the velocities of each person.
When Ian and Jaden meet:
t1 = d/(42+48) (d is in meters and t is minutes)
When Carter and Jaden meet:
t2 = d/(36+48)
Jaden passed carter 10 minutes after passing Ian, therefore:
t2 - t1 = d/84 - d/90 = 10
6d/7560 = 10
d = 10*7560/6
d = 12600 m = 12.6 km
Answer:
X = 9/2 or X = 3
Step-by-step explanation:
5x + 2 = 7x -7
5x - 7x = - 2 - 7
<u>2</u><u>x</u> =<u> </u><u>-</u><u>9</u>
2 2
X = - 9/2
or X = 3 (lowest term)
