Answer:

x = 4 and x = 2

Step-by-step explanation:

If this is the equation you're looking for: x^2 - 8x + 14 = 6 - 2x then here:

x^2 - 8x + 14 = 6 - 2x

x^2 +14 = 6 +6x

x^2 +8 = 6x

x^2 = 6x - 8

√x^2 = √6x - 8

x = 4 and x = 2

Henry's uncle from Japan promised to give him 35 g of gold. The local jewelry exchange will buy gold for $1224 per ounce. How mu
galina1969 [7]

Answer:

$1530

Step-by-step explanation:

First of all, it is required to convert 35g of gold into ounce.

Since,

1 oz = 28 g

or, we can write,

1 g = \frac{1}{28} oz

Now, for 35 g of gold, we can write,

35 * 1 g = 35 * \frac{1}{28} oz\\35 g = 1.25 oz

Since, local jewelry will buy at $ 1224 per oz, and we have 1.25 oz of gold, so,

1.25 * 1244\\$1530

Answer:

2.44745763 \times  {10}^{6}

Step-by-step explanation:

R =  \frac{ {x}^{2} }{y}  \\  \\  =  \frac{ {(3.8 \times  {10}^{5}) }^{2} }{5.9 \times  {10}^{4} }  \\  \\  =  \frac{14.44 \times  {10}^{10} }{5.9 \times  {10}^{4} }  \\  \\  = 2.44745763 \times  {10}^{10 - 4}  \\ = 2.44745763 \times  {10}^{6}

Please Help Me Asap I Need Units Too
Lina20 [59]

Hello and Good Morning/Afternoon

<u>Let's take this problem step by step</u>:

<u>To find the rate of change is essentially like finding a line's slope</u>:

 ⇒ the <em>x-values</em> are the <em>number of sodas</em>

 ⇒ the<em> y-values </em>are the <em>total costs</em>

<em>               ⇒ choose</em> two sets of coordinates and find the slope

<u>Let's put that into action</u>

  • Choose any two points

        ⇒ (24, 18)

        ⇒ (28, 21)

  • Calculate Slope

        Rate_.of_.change = \frac{21-18}{28-24} =\frac{3}{4}

<u>Since the rate of change is total cost over number of sodas</u>

 ⇒ <em>unit is '</em>total cost/number of sodas'

<u>Answer: 3/4 total cost/number of sodas</u>

<u></u>

Hope that helps!

What is the slope of a line that is perpendicular to the line 2x-4y=24
DanielleElmas [232]

Answer: y= -2x + 24

Step-by-step explanation

2x - 4y = 24

subtract 2x from both sides

divide 4y by 4y to get y by itself

then you get y= -2x + 24
