The best and most correct answer among the choices provided by your question is the second choice or letter B. <span>The slope of line CD is undefined.

By two-point slope form:
m=(y2-y1)/(x2-x1)
m=(8+7)/(4-4)
m=15/0 (undefined)
</span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly.

son4ous [18]

7 video games were in each case.

Step-by-step explanation:

-So, Ricardo has 2 cases of video games with the same amount of games per case.

-He gives 4 games to his brother and is left off with 10 games.

Add 10+4 to get the total amount of games.

Since there are 2 cases, divide the total amount of games (14) by the total amount of video game cases.

This gets us 7, which is the starting amount of video games in each case.

What is the value of the discriminant for the quadratic equation 0 = x + 2 + x^2?

aliya0001 [1]

Answer:

The discriminant of the quadratic equation is -7.

Step-by-step explanation:

We are given the following quadratic equation in the question:

$x^2+x+2 = 0$

Comparing to general quadratic equation:

$ax^2+bx+c = 0\\a = 1\\b = 1\\c = 2$

We have to find the discriminant of the quadratic equation.

Formula:

$d = b^2-4ac$

Putting values, we get,

$d = (1)^2 - 4(1)(2) = 1 - 8 = -7$

Thus, the discriminant of the quadratic equation is -7.

A chemist recorded the change in temperature of a cooling liquid as −25.5°F over a 1.5 minute period. The temperature fell at a

Strike441 [17]

The rate of change in temperature is −17°F/min

<h3>Rate of change of a function</h3>

The formula for calculating the rate of change of a function is expressed as:

Rate of change = rise/run

This is also known as the slope of the function

Given the following parameters

Temperature = −25.5°F

Cooling time = 1.5mins

Determine the rate of change

Rate = −25.5°F/1.5min

Rate = −17°F/min

Hence the rate of change in temperature is −17°F/min
