Complete the square for each expression. Write the resulting expression as a binomial squared. x^2-10x+_____

Answers

Answer 1

Answer:

[tex](x-5)^{2}[/tex]

Step-by-step explanation:

[tex]ax^{2} + bx + c[/tex]

Take the value for b, divide it by 2 and square it to get the value for c.

In this case, b = -10.

- 10 ÷ 2 = -5

-5^2 = 25

So x^2 - 10x +25 is your quadratic equation which is equal to

[tex](x-5)^{2}[/tex]

B) Non-Fiction = 4,800 books Fiction = 1,200 books

Hope this Helps! :)

Have any questions? Ask below in the comments and I will try my best to answer.

-SGO

Answers:

a) 80% nonfiction

b) 1200 fiction, 4800 nonfiction

=========================================

Explanation:

part (a)

We only have two choices: fiction or nonfiction

If 20% are fiction, then 100% - 20% = 80% are nonfiction.

The two percentages 20% and 80% add to 100% to represent all the books.

---------------------

part (b)

20% = 20/100 = 0.20

20% of 6000 = 0.20*6000 = 1200

we have 1200 fiction books

6000-1200 = 4800

and we have 4800 nonfiction books

Note how

80% of 6000 = 0.80*6000 = 4800

which helps confirm part (a)

(6x - 1)
X =

Answers

Answer:

the answer is -1

Step-by-step explanation:

Answer: x = 0

Step-by-step explanation: Firstly, set them equal to each other.

7x - 1 = 6x - 1

Now, subtract 6x from both sides:

x - 1 = -1

Add 1 to both sides:

x = 0

And if you need to know what type of function it is, it is an infinite function because if you plug in 0:

7(0) - 1 = 6(0) - 1

You get:

-1 = -1

If both sides are the same, it is an infinite function.

In one month, the median home price in the west fell from $203,400 to $192,300. Find the percent decrease

Answers

around 5.4572271...% decrease
(i’m not sure what to round it to)

subtract 192,300 from 203,400 to find the amount of change
(= 11,100)

then divide that amount from the original price (203,400)

then multiply that number by 100 to get a percent

finally round to a reasonable percent
203,400-192,300=11,100
11,100/203400= 5.46%
It decreased by 5.46%

alex is working to simplify 5·(-8)·2


A. what is the product?

B. suppose Alex found the opposite of the correct product. describe an error he could have made that resulted in that product.

please answer quickly!!!!!!!!!!!!

Answers

Answer:

A. 5*(-8)*2=-80

B. Forgot about the signs

Step-by-step explanation:

Product of Signed Integers

The product of two integers with like (same) signs is positive. The product of two integers with different signs is negative.

A.

Alex is simplifying the product 5*(-8)*2. It can be done in any order, for example, let's multiply 5*(-8) first.

The numbers have different signs, so the product is negative and 8*5 =40, thus:  5*(-8)=-40.

Now we finish the operation multiplying (-40)*2. They have different signs, thus the result is negative and (-40)*2=-80, thus:

5*(-8)*2=-80

B.

If Alex found the opposite of the correct product, that is, 80 is more likely to have been the result of forgetting about the signs. He probably just multiplied the numbers regardless of their signs.
