Answer:

b = -6.307 or -11.693

Step-by-step explanation:

b^{2} +9b +13\\

This can't be factored so you need to use the quadratic formula which is

-b ± \frac{\sqrt{b^{2} -4ac}}{2a}

Plugging the numbers from the equation in, it's

-(9) ± \frac{\sqrt{(9)^{2}-4(1)(13) } }{2(1)}

This simplifies down to b = -6.307 or -11.693.

These are both real solutions.

Which equation represents the line that is perpendicular to and passes through (-40,20)?
emmasim [6.3K]

The equation of the perpendicular line to the given line is: y = -5/4x - 30.

<h3>What is the Equation of Perpendicular Lines?</h3>

The slope values of two perpendicular lines are negative reciprocal of each other.

Given that the line is perpendicular to y = 4/5x+23, the slope of y = 4/5x+23 is 4/5. Negative reciprocal of 4/5 is -5/4.

Therefore, the line that is perpendicular to it would have a slope (m) of -5/4.

Plug in m = -5/4 and (x, y) = (-40, 20) into y = mx + b to find b:

20 = -5/4(-40) + b

20 = 50 + b

20 - 50 = b

b = -30

Substitute m = -5/4 and b = -30 into y = mx + b:

y = -5/4x - 30

The equation of the perpendicular line is: y = -5/4x - 30.
