Given:

The equation is

\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1

To find:

The solution of the given equation.

Solution:

We have,

\left(z+\dfrac{6}{7}\right)+\dfrac{2}{14}=-1

It can be written as

\left(z+\dfrac{6}{7}\right)+\dfrac{1}{7}=-1

\left(z+\dfrac{6}{7}\right)=-1-\dfrac{1}{7}

Multiply both sides by 7.

7z+6=-7-1

7z+6=-8

7z=-8-6

7z=-14

Divide both sides by 7.

z=\dfrac{-14}{7}

z=-2

Therefore, the value of z is -2.

If a line segment contains one endpoint at (2,3) and has a midpoint of (-2,6) what is the second endpoint of the line segment
olchik [2.2K]

Answer:

Step-by-step explanation:

The coordinates of the midpoint M are the average of the coordinates of the two endpoints:

M_x = \dfrac{2+x}{2},\quad M_y = \dfrac{3+y}{2}

Plug the known coordinates of the midpoint:

-2 = \dfrac{2+x}{2},\quad 6 = \dfrac{3+y}{2}

Solve for x and y:

-4 = 2+x,\quad 12 = 3+y

x=-6,\quad y = 9

Explain how to use the discriminant to determine the number and type of roots of a quadratic equation.
baherus [9]

The general form of the quadratic equation is :

ax^2+bx+c=0

The discriminant is :

D=b^2-4\cdot a\cdot c

And the general solution is :

x=\frac{-b\pm\sqrt[]{D}}{2\cdot a}

So, there are 3 situations for D

1. D = 0

So, the roots of a quadratic equation are two similar roots

2. D > 0

so, roots of a quadratic equation are two different roots

3. D < 0

so, roots of a quadratic equation are not real, two comlex roots
