Answer:

$x=-\frac{3}{2}$

Step-by-step explanation:

$-3x+x=2(x-3)\\ \Leftrightarrow -2x=2x-6\\ \Leftrightarrow 4x=-6\\ \Leftrightarrow x=-\frac{3}{2}$

Answer:

It could fly 10,8 kilometers.

Step-by-step explanation:

The European swallow fly speed is 12 meters per second.

We have to calculate how many kilometers it could fly in 15 minutes.

This can be calculated using the equivalent factors for each of the units:

- 1 km is equivalent to 1,000 meters.

- 1 minute is equivalent to 60 seconds.

We know that the distance travelled by the fly is the product of the speed and the time, so we have:

$D=v\cdot t\\\\\\D=12\,\dfrac{m}{s}\cdot15\, min\\\\\\D=12\,\dfrac{m}{s}\cdot(\dfrac{1\,km}{1,000\,m})\cdot15\, min\cdot (\dfrac{60\,s}{1\,min})\\\\\\D=\dfrac{12\cdot 15\cdot 60}{1,000}\,km=\dfrac{10,800}{1,000}\,km\\\\\\D=10,8 \,km$

choose the equation below that represents the line passing through the point (2, −4) with a slope of one half. a. y = 1/2x 5 b.

ICE Princess25 [194]

The point-slope form: $y-y_0=m(x-x_0)$

$m=\dfrac{1}{2};\ (2;-4)\to x_0=2;\ y_0=-4$

subtitute

$y-(-4)=\dfrac{1}{2}(x-2)\\\\\boxed{y+4=\frac{1}{2}(x-2)}$

What is the equation in slope-intercept form of the line that passes through the points (−26, −11) and (39, 34)?

Scrat [10]

The equation in slope-intercept form of the line passing through the given points is: C. $y = \frac{9}{13}x + 7$

<u>Given the following points:</u>

Points on the x-axis = (-26, 39)

Points on the y-axis = (-11, 34)

To find the equation in slope-intercept form of the line passing through the given points:

Mathematically, the equation of slope is calculated by using this:

$Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}$

Substituting the given points, we have:

$Slope. \;m = \frac{34 - [-11]}{39 - (-26)}\\\\Slope. \;m = \frac{34\; + \;11}{39 \;+ \; 26}\\\\Slope. \;m = \frac{45}{65}\\\\Slope. \;m = \frac{9}{13}$

The standard form of an equation of line is given by the formula;

$y = mx + b$

Where:

x and y are the points.

m is the slope.

b is the intercept.

We would find the intercept:

$-11 = \frac{9}{13}(-26) + b\\\\ -11 = -18 + b\\\\b = -11 + 18$

Intercept, b = 7

The equation in slope-intercept form of the line is:

$y = \frac{9}{13}x + 7$
