Write an equation for a direct variation that includes the point (3, 18)
erma4kov [3.2K]
Direct variation means that the line goes through the origin of the graph, so you know that the line must go through point (0,0). Using that along with the given point, you can find the slope of the line.

m = \frac{y_2 - y_1}{x_2 - x_1}
m = \frac{18 - 0}{3 - 0}
m = \frac{18}{3}
m = 6

Now that you know the slope of the line you are looking for is 6, you can plug that into a point-slope form equation and find the equation of your line.

y - y_1 = m (x - x_1)   Plug in either set of coordinate. I chose (3, 18).
  y - 18 = 6 (x - 3)        Use he Distributive Property
  y - 18 = 6x - 18         Add 18 to both sides
        y = 6x

The equation of a direct variation line that includes the point (3, 18) is y = 6x.

What number must you add to the polynomial below to complete the square? x^2+17x
Juliette [100K]

The number added to the polynomial by completing the square is \frac{289}{4}

Explanation:

Given that the polynomial is x^{2} +17x

We need to determine the number that is added to the polynomial to complete the square.

The last term of the polynomial can be determined by dividing the term 17 by 2 and then squaring the term.

Thus, we have,

Last term = \frac{17}{2}

Now, squaring the term, we have,

Last term = (\frac{17}{2})^2=\frac{289}{4}

Thus, the number added to the polynomial by completing the square is \frac{289}{4}
