Answer:
150 seconds
Step-by-step explanation:
Remember that

To convert miles to feet multiply by 5,280

To convert hours to seconds, multiply by 3,600
step 1
Convert the average rate of miles per hour to feet per second

step 2
Find out how many seconds does the ride take to travel this length of track
we know that
The length of the track is 3,300 ft
so
Divide the total length of the track by the speed

Answer:
The slope is $0.35/min and it gives the cost per minute of the phone used.
Step-by-step explanation:
We can model this situation with a linear equation of the form

where
is monthly cost,
is the number of minutes,
is the flat monthly fee, and
is the slope of the equation, or in our case, the amount of money charged per minute.
The slope
is

,
in other words, the phone company charges $0.5 per minute.
With the slope in hand, the linear equation becomes
,
and we can find the monthly fee
from that fact that for 300 minutes the cost is $131:

.
Therefore,

where the slope if the equation give the cost per minute of the phone used.
Answer:

Answer:
5
Step-by-step explanation:
since -4 *-2 = 8 and -8+8=0
0*-2=0
0+5=5
Answer:
a = 10, b = -12
Step-by-step explanation:
4+2(5x-8) = ax +b
4 + 10x - 16 = ax + b
10x - 12 = ax + b
Infinitely many solutions when:
a = 10
b = -12
