Answer: Second Option is correct.

Step-by-step explanation:

Since we have given that

x^2+5x-6=0

We need to calculate the solutions to the equation :

We will use "Split the middle terms" :

x^2+5x-6=0\\\\x^2+6x-1x-6=0\\\\x(x+6)-1(x+6)=0\\\\(x+6)(x-1)=0\\\\x+6=0;x-1=0\\\\x=-6,1

So, Second Option is correct.

The quadratic equation is;
x²+5x-6 = 0
x²+6x-x-6 = 0
x(x+6)-1(x+6) = 0
(x+6)(x-1) = 0
So,
x+6 = 0 and x-1 = 0
x=-6 and x = 1
Thus the answer is
x = -6,1

21. For the following exercises, use the descriptions of each pair of lines given below to find the slopes of Line 1 and Line 2.
dybincka [34]

Answer:

The given lines are perpendicular.

Step-by-step explanation:

In the question, two lines are given as line 1 passes through (1,7) and (5,5). Whereas, line 2 passes through (-1,-3) and (1,1).

It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.

To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.

Step 1 of 2

Find the slope of first line.

$$\begin{aligned}m_{1} &=\frac{5-7}{5-1} \\m_{1} &=\frac{-2}{4} \\m_{1} &=-\frac{1}{2}\end{aligned}$$

Step 2 of 2

Find the slope of first line.

$$\begin{aligned}&m_{2}=\frac{1-(-3)}{1-(-1)} \\&m_{2}=\frac{4}{2} \\&m_{2}=2\end{aligned}$$

And

$$\begin{aligned}&m_{1} m_{2}=-\frac{1}{2}(2) \\&m_{1} m_{2}=-1\end{aligned}$$

Since, both slopes are reciprocal of each other.

Therefore, the lines are perpendicular.

Olenka [21]

Answer:

Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).
