Answer:
63
Step-by-step explanation:
Step 1: Define
f(x) = -x - 12
f(-5) is x = -5
f(-3) is x = -3
Step 2: Find f(-5)
f(-5) = -(-5) - 12
f(-5) = 5 - 12
f(-5) = -7
Step 3: Find f(-3)
f(-3) = -(-3) - 12
f(-3) = 3 - 12
f(-3) = -9
Step 4: Find f(-5) × f(-3)
-7 × -9

Answer:
0
Step-by-step explanation:
The slope is the change in y divided by the corresponding change in x:
∆y/∆x = (54.99 -54.99)/(7 -6) = 0/1 = 0
The slope of the line is zero.

Answer:
85 km/h
Step-by-step explanation:
Let s represent the speed of the slower car. Then the travel time is ...
time = distance/speed
2 = 360/(s +(s+10))
4s +20 = 360 . . . . . multiply by 2s+10
4s = 340 . . . . . . . . . subtract 20
s = 85 . . . . . . . . . . . divide by 4
__
The rate of the slower car is 85 km/h.
