What is the constant of variation, k, of the line y=kx through (3,18) and (5,30)?

6

Step-by-step explanation:

In this instance, the constant of variation is the same as the slope.  The formula for slope is:

Using the points we're given, we have

The constant of variation is 6.

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.
