Y = 40 when x = 16, so 40 = k/16

Therefore, k = 640

So, y = 640/x

First we graph the given points

For the equation to be proportional, the line should pass through the origin (0,0), then this equation is not proportional.

Solve the following absolute value equation.

dolphi86 [110]

Hey there!

$|\displaystyle\frac{x-1}{2} |=7$

Let's say that x-1 is negative:

$\displaystyle\frac{-x+1}{2} =7$

The first step is to multiply both sides by 2:

$\text{-x+1=14}$

Now, move 1 to the right, using the opposite operation:

$\text{-x=14-1}$

$\text{-x=13}$

Divide both sides by -1:

$\text{x=-13}$

Note: Since the negative sign is already entered, all you need to enter is 13.

I hope you find my answer helpful.

Good luck!

Have a great day!

Can someone answer this so i can check if im right?

Answer:

Step-by-step explanation:

There are 3 possible triangles to find there within what appears to be one triangle. And since they are all part of the same largest triangle, they are also all similar. Just because 2 shapes may be triangles, so NOT mean they are automatically similar. Remember that!

The largest triangle is ΔABC

The triangle on the "left" is ΔADB, and

The triangle on the "right" is ΔCDB
