The correct answer is Concurrent Lines. In geometry, when three or more lines in a plane or a higher dimensional space intersect at a single point, the lines are said to be concurrent.

A plane flew 145km/h faster when it was flying with the wind than it would have flown with still air, if it’s speed with the win

pshichka [43]

Answer:

Speed of plane in still air = 825 km/h

Step-by-step explanation:

Given:

Speed of plane with the wind is 145 km/h faster than what it would have with still air.

Speed of plane with wind = 970 km/h

To find speed of plane in still air.

Solution:

Let speed of plane in still air be = $x$ km/h

Thus speed of plane with wind would be given as = $(x+145)$ km/h

Speed of plane with wind is given =970 km/h

So, we have:

$x+145=970$

Solving for $x$ .

Subtracting both sides by 145.

$x+145-145=970-145$

∴ $x=825$ km/h (Answer)

Thus, speed of plane in still air = 825 km/h

Answer the linear inequality

PolarNik [594]

Substitute x-values into x.
e.g. y>-3.5x + 2
let x be 1...
thus, y>-3.5(1) + 2
y> -1.5 or y<1.5
another e.g. let x be 2.
y> -3.5(2) + 2
y> -4.4 or y<4.4
And so forth. pluck in these coordinates into you graph and sketch a line through the points.
NOTE: < in my explanation is equivalent to less than or equal to. same goes to >… greater than or equal to.

I hope you followed through. Good luck!

12 • 16 = 192

5 • 3.14 = 15.7 15.7/2= 7.85

192 + 7.85 = 199.85

The area of the objective is 199.85
