Select the two values of x that are roots of this equation. 2x2 + 11x+15= 0

USPshnik [31]

Answer:

The two values of x are -2.5 and -3

Step-by-step explanation:

we have

$2x^{2}+11x+15=0$

The formula to solve a quadratic equation of the form $ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$a=2\\b=11\\c=15$

substitute in the formula

$x=\frac{-11(+/-)\sqrt{11^{2}-4(2)(15)}} {2(2)}$

$x=\frac{-11(+/-)\sqrt{1}} {4}$

$x=\frac{-11(+/-)1} {4}$

$x_1=\frac{-11(+)1} {4}=-2.5$

$x_2=\frac{-11(-)1} {4}=-3$

therefore

The two values of x are -2.5 and -3

Find the slope of the line that passes through (4,2) and (4,5)

Hunter-Best [27]

Answer: Undefined

Step-by-step explanation:

(slope = m)

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{4-4}=\frac{3}{0}$

(3 divided by 0 is undefined, so the slope is undefined)
