Not only can be more easily understood by some people, but it can also illustrate the exact course a line will take rather than just giving some of the coordinates. Furthermore, a graph is less accurate due to the fact that lines are infinite and can express all the numbers they cross rather than just giving a limited amount of numbers.
Answer:
m < 15
Step-by-step explanation:
2m+10 < 40
Subtract 10 from each side
2m+10-10 < 40-10
2m < 30
Divide by 2
2m/2 = < 30/2
m < 15
Answer:
Step-by-step explanation:
If v = plane velocity and c = air current, then:
v + c = 480
v - c = 400
2v = 880
v = 440
The plane's velocity in still air would be 440 miles per hour.
Answer:
<em>4x² + 4x + 8 </em>
Step-by-step explanation:
P = 2( 2x² - 3x + 1 ) + 2( 5x + 3 ) = 4x² - 6x + 2 + 10x + 6 = 4x² + 4x + 8
<em> 4x² + 4x + 8</em>
