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

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

Hello and Good Morning/Afternoon

Let's take this problem step by step:

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

⇒ the x-values are the number of sodas

⇒ the y-values are the total costs

⇒ choose two sets of coordinates and find the slope

Let's put that into action

Choose any two points

⇒ (24, 18)

⇒ (28, 21)

Calculate Slope

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

Since the rate of change is total cost over number of sodas

⇒ unit is 'total cost/number of sodas'

Answer: 3/4 total cost/number of sodas

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
