Answer:
Option 3
Step-by-step explanation:
All equations are in slope-intercept form. 
The 'm' is the slope.
The 'b' is the y-intercept.
The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.
<em>Let's look over the equations:</em>
<h3>Equation A:</h3>

In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
<h3>Equation B:</h3>

In this equation, 3 replaces 'm', so the rate of change for this equation is 3.
<h3>Equation C:</h3><h3>

</h3>
In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
<h3>Equation D:</h3><h3>

</h3>
In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.
Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.
It is 2 inches long this is because of the length of the hands .
Answer:
Train A is 287 tons
Train B is 94 tons
Step-by-step explanation:
My method of solving it may have been a bit different from how you were taught. I divided 381 by 2 to give both trains an equal weight of 190.5 tons. I then divided the difference, 193, by 2 to get 96.5 tons. I subtracted the new difference from the weight of Train B and added it to train A. To double check, you can grab a calculator and see that their weights are equal to 381.
Using synthetic division, you can find the quadratic factor to be
.. 2x^2 -3x +1
That, in turn, factors as
.. (2x -1)(x -1)
So the complete factorization is
.. (2x -1)(x -1)(x +3)
and the zeros are confirmed by a graphing calculator to be
.. x = 1/2, 1, -3
Yeah it can so u divide long way
