Find the roots of the quadratic equation x^2-8x=9 by completing the square. Show your work.

Answer:

The answer is the attached figure

Step-by-step explanation:

* Lets explain mutually exclusive and non-mutually exclusive

- The mutually exclusive means events cannot happen  at the

 same time

# P(A or B) = P(A) + P(B)

- The non-mutually exclusive means they  have at least one

 outcome in common

# P(A or B) = P(A) + P(B) - P(A and B)

* Lets solve the problem

∵ Events A and B are mutually exclusive

∵ Circle A represents the event A

∵ Circle B represents the event B

∴ There is no intersection between the two circles A and B

∵ Events B and C are non-mutually exclusive

∵ Circle C represents the event C

∴ There is an intersection between the two circles B and C

* The answer is the attached figure

Answer: D. image 4.

Just did assignment.

The slope of the line represented by this equation is 4/5.

We know this because this line is in slope-intercept form, y=mx+b, where m represents the slope and b represents the y-intercept. Thus, we can conclude that the slope is 4/5, which means that for every 4 units the line moves up, it also moves 5 units over (because slope is defined as rise/run).

Hope this helps!

The required percentages obtained by calculations is 73. In other words, 73% of approximately 214.7945 is equal to 156.4.

To find 73% of a certain value, we can set up an equation and solve for that value. Let's denote the unknown value as "x".

The equation would be:

0.73 * x = 156.4

To isolate x, we divide both sides of the equation by 0.73:

x = 156.4 / 0.73

Evaluating this expression:

x ≈ 214.7945

Therefore, the required percentages obtained by calculations is 73. In other words, 73% of approximately 214.7945 is equal to 156.4.

Answer: The answer is zero/0 That is because an opposite of a positive integer would be a negative.  

An example is-

3 >>> its opposite is -3,

3 + -3 = 0
