Find an equation that passes through the points (2,4) and is perpendicular to the line 3x+4y-22=0
elena-14-01-66 [18.8K]

Hello:<span>
the equation is : y = ax+b
the slope is a : a×(-3/4) = -1......( perpendicular to a line : </span>

3x+4y-22=0  : another equation is : y = (-3/4)x +22/4 with the slope : (-3/4))

<span>
a =4/3   </span>

 

<span>an equation  is : y - 4 = (4/3)(x-2)</span>

Which two values of x are roots of the polynomial below x^2 - 11x + 13
matrenka [14]

Because 13 is a prime number, we cannot use the AC method to simplify.

We can instead use the quadratic formula.

\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

11 +/- √121 - 52 / 2

11 +/- √69 / 2

11 +/- 8.3 / 2

(11 + 8.3)/2 = 9.65

(11 - 8.3)/2 = 1.35

<h3>The roots of the polynomial are 9.65 and 1.35.</h3>
