Answer:

t = -1

Step-by-step explanation:

-4 = 2t - 2

Add 2 on both sides.

-4 + 2 = 2t - 2 + 2

-2 = 2t

Divide both sides by 2.

-2/2 = (2t)/2

-1 = t

Which equation has the components of 0 = x2 – 9x – 20 inserted into the quadratic formula correctly?

Aneli [31]

Answer:

The required equation is $x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$ .

Step-by-step explanation:

If a quadratic equation is $ax^2+bx+c=0$ , then the quadratic formula is

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

The given quadratic equation is

$x^2-9x-20=0$

Here, a=1, b=-9 and c=-20.

Substitute a=1, b=-9 and c=-20 in the above quadratic formula.

$x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$

Therefore the required equation is $x=\frac{-(-9)\pm \sqrt{(-9)^2-4(1)(-20)}}{2(1)}$ .

I just want to check my answer, what is the slope of (-19, -6), (15,16)?

galina1969 [7]

$slope=\frac{y_2-y_1}{x_2-x_1}\\\\ 
(x_1,y_1)=(-19,-6)\\ 
(x_2,y_2)=(15,16)\\\\
 slope=\frac{16+6}{15+19}=\frac{22}{34}=\frac{11}{17}\\\\
Slope\ is\ equal\ to\ \frac{11}{17}.
