Answer:
Step-by-step explanation:
slope = y2-y1/x2-x1
Given the coordinates (k,6k) and (3k,10k)
x1 = k
y1 = 6k
x2 = 3k
y2 = 10k
Substitute
slope = 10k-6k/3k-k
slopw = 4k/2k
slope = 4/2
slope = 2
Hence the slope of the line is 2
At 900 miles, the cost for the two rentals will be same.
Step-by-step explanation:
Given,
A+ Auto rental: $175 plus $0.10 per mile
Let,
x be the number of miles.
y be the total distance.
y = 0.10x+175 Eqn 1
Zippy Auto rental: $220 plus $0.05 per mile
y = 0.05x+220 Eqn 2
When Eqn 1 = Eqn 2, the cost will be same
Therefore;
Dividing both sides by 0.05
At 900 miles, the cost for the two rentals will be same.

A)m=40
a straight line is equal to 180 degrees so do 180-115 to get the inside part of the triangle then add that number to 75 and take the sum of that and subtract it from 180 because any triangle is equal to 180
Answer: the speed of the commercial jet is 540 mph
the speed of the private airplane is 330 mph
Step-by-step explanation:
Let x represent the speed of the commercial jet and
Let y represent the speed of the private airplane.
It takes the commercial jet 1.1 hours for the flight from Denver to Phoenix.
Distance = speed × time
Therefore, distance covered by the commercial jet from Denver to Phoenix would be
1.1 × x = 1.1x
it takes the private airplane 1.8 hours to cover the same distance. The speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane. It means that
y = x - 210
Distance covered by the private airplane would be
1.8(x - 210) = 1.8x - 378
Since the distance is the same, then
1.8x - 378 = 1.1x
1.8x - 1.1x = 378
0.7x = 378
x = 378/0.7 = 540
y = x - 210 = 540 - 210
y = 330
