Question

X1=4+0,5t x2 = 8- 2t t-? x - ?

Answer 1

Это 2 вектора и надо найти их время и координату пересечения, если они встретились значит х1=х2
4+0,5t=8-2t
2.5t=4
t=1.6

подставим t в любое уравнение
x=4+0.5*1.6
x=4.8

Answer 2

It looks like you have two equations with two variables, x1 and x2, in terms of the parameter t:

1. x1 = 4 + 0.5t
2. x2 = 8 - 2t

If you want to find the values of t for a specific pair of (x1, x2), you can set up a system of equations and solve for t. For example, if you have specific values for x1 and x2, let's say x1 = 6 and x2 = 4, you can set up the following equations:

1. 6 = 4 + 0.5t
2. 4 = 8 - 2t

Now, you can solve this system of equations for t. First, isolate t in the first equation:

6 = 4 + 0.5t Subtract 4 from both sides: 2 = 0.5t

Now, divide by 0.5:

2 / 0.5 = t t = 4

So, for x1 = 6 and x2 = 4, the value of t is 4.

You can similarly solve for t for other pairs of (x1, x2) by plugging in the values into the equations and solving for t.
