Answer:

2

Step-by-step explanation:

-6+10x=x+12

Add 6 to both sides:

10x=x+18

Subtract x from both sides:

9x=18

Divide both sides by 9:

x=2

Answer:

$F = 1.8C + 32$

Step-by-step explanation:

Given

The attached table

Required

The relationship between both temperatures

<em>This implies that we calculate the table equation</em>

First, we calculate the slope (m)

$m = \frac{F_2 - F_1}{C_2 - C_1}$

Where:

$(C_1,F_1) = (0,32)$

$(C_2,F_2) = (20,68)$

So, we have:

$m = \frac{68 - 32}{20 - 0}$

$m = \frac{36}{20}$

$m = 1.8$

The equation is then calculated using:

$F = m(C - C_1) + F_1$

This gives:

$F = 1.8(C - 0) + 32$

$F = 1.8(C ) + 32$

$F = 1.8C + 32$

Answer:

60°

Step-by-step explanation:

x + 160° + 140° = 360°

x + 300° = 360°

x = 360° - 300°

x = 60°

سا (a) From the definition of derivatives determine dy÷dx if y = -2÷x

harina [27]

Step-by-step explanation:

Given: $y = -\dfrac{2}{x}$

Derivative of a power function $x^n$ :

$\dfrac{d}{dx}(x^n) = nx^{n-1}$

Therefore,

$\dfrac{dy}{dx}=-2(-1)x^{-2} = \dfrac{2}{x^2}$
