Answer:

Einstein's Big Idea homepage. E = mc2. It's the world's most famous equation, but what does it really mean? "Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

Train A and Train B start off at the same point and are traveling in the same direction. It takes Train A 30 minutes to get to S

kaheart [24]

Answer:

No difference

Step-by-step explanation:

The given parameters are;

The point Train A starts off = The point Train B starts off

The direction of travel of Train A = The direction of travel of Train B

The time it takes Train A to get to Station X, t₁ = 30 minutes = 0.5 hour

The speed of Train A, v₁ = 100 miles per hour

The time it takes Train B to get to Station Y, t₂ = 100 minutes = (5/3) hours

The speed of Train B, v₂ = 30 miles per hour

The distance from the starting point to Station X, d₁, is given as follows;

v₁ = d₁/t₁

∴ d₁ = v₁ × t₁

By substituting the known values, we have;

d₁ = 100 mph × 0.5 h = 50 miles

The distance from the starting point to Station Y, d₂, is given as follows;

v₂ = d₂/t₂

∴ d₂ = v₂ × t₂

By substituting the known values, we have;

d₂ = 30 mph × (5/3) h = 50 miles

Therefore;

The difference in the distances to Station X and Station Y = d₁ - d₂

d₁ - d₂ = 50 miles - 50 miles = 0

∴ The difference in the distances to Station X and Station Y = 0 (No difference).

Answer:

The result for an input of 7 is: $y=15$

The output (y-value) associated with an input of 3 is: $y=7$

Step-by-step explanation:

The image attached shown the graph for the rule $y= 2x+1$ .

In order to use the graph to predict the result for an input value of 7, you need to follow these steps:

- Draw a vertical line from $x=7$

- When the vertical line touches the graph, you must draw a horizontal line to the y-axis to find the y-value.

You can observe in the graph that the result for an input value of $x=7$ is $y=15$

Follow these steps in order to use the graph to predict the output value associated with an input value of 3:

- Draw a vertical line from $x=3$

- When the vertical line touches the graph, you must draw a horizontal line to the y-axis to find the y-value.

You can observe in the graph that the output value associated with an input value of $x=3$ is $y=7$
