Answer: (x+-0.5)²=0

Step-by-step explanation:

4x²-4x+1=0

(2x-1)²=0 ⇔ completing the square

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

since the question asked for the x should be 1, then we should divide 2x by 2 so to get rid of the 2 in front of the x.

this will change the original equation into: (x+(-0.5))²=0

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

You can also directly divide 4 from 4x²-4x+1=0 to get rid off the terms in front of x.

x²-x+0.25=0

(x-0.5)²=0

(x+(-0.5))²=0

Step-by-step explanation:

Hey, there!

Here,

= 4 {x}^{2}  - 4x + 1

or ,\: ( {2x)}^{2}  - 2.2x .1 + 1

or ,\: ( {2x - 1)}^{2}

We got this because,

( {2x - y)}^{2}  = 4 {x}^{2}  - 4x + 1

By using formula,

( {x - y)}^{2}  =  {x}^{2}  - 2xy + 1

Consider that your profit-maximizing quantity of 500 can be produced at an average cost per unit of $9 and sold for a market pri
timama [110]

Based on the quantity sold and the price, the profit per unit is <u>$5</u> and the total profit is<u> $2,500</u>

The profit made from each unit sold can be found as:

<em>= Market price - Average cost </em>

= 14 - 9

= $5

The total profit would therefore be:

<em>= Profit per unit x Number of units sold </em>

= 5 x 500

= $2,500

In conclusion, the profit per unit is $5 and the total profit is $2,500

Item 12 You win an online auction for a toy. Your winning bid of $52 is 65% of your maximum bid. How much more were you willing
nataly862011 [7]

Answer:

$28

Step-by-step explanation:

Given that:

Value of Winning bid = $52

Winning bid 65% of the maximum bid.

To find:

How much more is the maximum bid from the winning bid ?

Solution:

We are given that the winning bid is 65% of the maximum bid.

Using this percentage value, we need to first find the value of maximum bid and then we need to subtract the value of winning bid from the maximum bid to find the answer.

Let the value of maximum bid = $x

As per question statement:

65%\ of\ x = 52\\\Rightarrow \dfrac{65}{100} \times x =52\\\Rightarrow 5x = 400\\\Rightarrow x = \dfrac{400}{5}\\\Rightarrow x =\$80

Therefore, maximum bid = $80

Our answer is:

$80 - $52 = <em>$28</em>

Teresa stated that the heights of the students in her class were not a function of their ages. Which reasoning could justify Ter
jenyasd209 [6]
<h2>Answer:</h2>

Option: A is the correct answer.

A.  Two students are the same age but have different heights.

<h2>Step-by-step explanation:</h2>

The height of a student could not be a function of the ages of a student because two or more students with the same age may have the different heights .

This means that a value on a x-axis (i.e.  age) is mapped to two or more  values i.e. corresponding y-value ( i.e.  different heights) which violates the definition of function.

Hence, option: A is the correct answer.
