Any and all help would be appreciated!
SpyIntel [72]

The way we can find out the unit rate (also known as the <em><u>SLOPE</u></em>) is by using the table as coordinates!

The slope formula is \frac{y2 - y1}{x2 -x1}

With the table, the TIME column can be "x"

The DISTANCE column can be "y"

____________________________

As coordinates, it would look like...

(0,0)

(20, 25)

(30, 37.5) and so on!

_____________________________

All we need to do now is use 2 of these coordinates and plug them into the slope formula in their correct places to find the unit rate!

Example:

solve!

\frac{37.5 - 25}{30 - 20} = 12.5/10 ⇒ 1.25 ( or 5/4 in fraction form)

Solve the equation using the quadratic formula
amm1812

Answer:

Step-by-step explanation:

Rewrite this quadratic equation in standard form:  2n^2 + 3n + 54 = 0.  Identify the coefficients of the n terms:  they are 2, 3, 54.

Find the discriminant b^2 - 4ac:  It is 3^2 - 4(2)(54), or -423.  The negative sign tells us that this quadratic has two unequal, complex roots, which are:

     -(3) ± i√423        -3 ± i√423

n = ------------------- = ------------------

             2(2)                      4
