X + y > = 36 (thats greater then or equal)
2x + 0.6y < 40
Answer:
<em>See the graph with both lines attached</em>
A) From the tables we see the constant change of values in the second column and the initial value is zero.
This represents a proportional relationship for both tables.
B) <u>Revel</u>
- Rate of change is 5 per hour, the equation is:
- y = 5x, where y is cost, x - is the number of hours
<u>Scooters</u>
- Rate of change is 6 per hour, the equation is:
- y = 6x, where y is cost, x - is the number of hours
C) <u>When x = 12</u>,
- y = 5*12 = $60 for Revel
- y = 6*12 = $72 for Scooters
D) <u>The point (4, 24) represents that:</u>
- The cost of 4 hours is $24
E) The second table has confusing titles (days and number of cell phones) but if we assume its same as the first table, then Revel has lower rate as 5 < 6.
Comparing the prices and the graph, Revel has better rate per hour.
Speed is distance/time
90/1.5 = 60 mph
in 6 hours you would travel 360 miles because 6 • 60 is 360.
Find what x is first. since it's a regular polygon all the sides are equal. so 3(x-1) = 5x-6. once you find x put it in one of the sides and multiply the length of the side by the amount of sides.
