Answer:

x=4

Step-by-step explanation:

"A number" can be rewritten as X:

6x=3x+12

1) subtract 3x on both sides:

3x=12

2) divide both sides by 3:

x=4

Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite th
Advocard [28]

Answer:

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

Step-by-step explanation:

<u>Let's convert the standard equation into slope-intercept form:</u>

  • Ax + By = C              ⇒ subtract Ax from both sides
  • By = -Ax + C             ⇒ divide both sides by B
  • y = -A/Bx + C/B        ⇒ converted to slope- intercept form

As we see the slope is -A/B

<u>The equation 7x + 9y = 14 is converted as:</u>

  • y = -7/9x + 14/9, where the slope is -7/9

<u>Looking at the answer options and the correct one is option B, where both identification of slopes match.</u>

  • B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

Frank purchased an air conditioner for $3000. Its value depreciates at a rate of 8% each year. How much will the air conditioner
Lina20 [59]

Answer:

$2280

Step-by-step explanation:

Given: Cost of Air conditioner= $3000.

            Rate of depreciation= 8%

            Number of year= 3 years.

Now, finding the depreciation for 3 years.

Depreciation= \frac{Cost\ of\ air\ conditioner\times rate\ of\ depreciation\times years}{100}

Amount of depreciation= \frac{\$ 3000\times 8\times 3}{100} = \$ 30\times 24

∴ Amount of depreciation in 3 years is $720.

Cost of Air conditioner after 3 years= Original\ cost - Amount\ of\ depreciation

⇒ Cost of Air conditioner after 3 years= \$ 3000-\$ 720= \$ 2280.

∴ Cost of Air conditioner in 3 years is $2280.
