Answer:
x = 15, y = 4
Step-by-step explanation:
To solve this, we have to define the triangles first. Since the triangles are congruent by HL, it means that the hypotenuse and the leg of the triangle are defined to be equal. By flipping one of the triangles upsidedown, we can visualize the hypotenuse of the triangles and the leg of the triangles (which are equal).
The two equations are the following:


If I add 1 to both sides of the second equation, I get the following equation:

By comparing this new equation with the first one, we will get:

We can ignore x+1 for now since y can not be solved.

By subtracting both sides of this equation by y, we will get.

This solves for y, where

Now, we can re-use one of the equations, which is

Now that we know y is 4, we can plug it into this equation.

2x +2(x-12)=340
2x+2x-24 = 340
4x=364
x = 91
91-12 = 79 mph for eastbound train
Answer:
x > 3
Step-by-step explanation:
The first part is to solve the inequality, which is very easy:
2x - 1 > x + 2, so 2x - x > 2 + 1 so
x > 3
Then we have to graph the solution... that's also easy. It will look like the graph attached, meaning it includes ALL the values X > 3 (that's why the line is dashed on the 3), for ALL the values of Y.
That's a weird graphic, but it does represent the inequality we found.
