If solving for x:
Because both equations are equal to Y, you can set both equations equal to each other:
5x+1=4x+8
Then it's a matter of simplification (subtract the 4x to the left side and subtract the 1 over to the right):
x=7
If solving for Y:
Plug x=7 into either equation and solve:
Y=4(7)+8
Y=36

A plane traveling with a velocity measured in meters per second, is described by vector a = 5,6). Find the

ryzh [129]

Answer:

The speed of the plane is $v=1.2\: m/s$

Step-by-step explanation:

The vector (5,6) represents a point in the coordinate system time-position.

So, we have that at t = 5 s the position is x = 6.

Let's recall that the slope of this vector is the speed, then using the tangent definition:

$v=\frac{x}{t}=\frac{6}{5}$

$v=1.2\: m/s$
