The range is [4,∞)
Or from 4 to positive infinity
Or y is greater than or equal to 4
<em>Exterior angle of the triangle is equal to the sum of the opposite angles.</em>
9x = 5x + 9 + x
<em>Combine like terms:</em>
9x = 6x + 9
<em>Take away 6x from both sides:</em>
3x = 9
<em>Divide by 3 on both sides:</em>
x = 3
Answer: x = 3
The answer to this is 756 hours. Because first you must multiply the number of miles each flight is x the miles per minute. Next you multiply that answer by the number of trips. The answer would be how many minutes, but the question asks "how many hours", and there's 60 minutes in an hour so divide that answer by 60 and that will equal 756 hours.
Answer:
The answer is C
Step-by-step explanation:
I got it correct :)
Subsitution is subsituting
y=3x-2
y=-x+6
subsitute 3x-2 for y in second equation
3x-2=-x+6
add x to both sides
4x-2=6
add 2 to both sides
4x=8
divide both sides by 4
x=2
subsitute
y=-x+6
y=-2+6
y=4
x=2
y=4
