How to solve a equation like:<br> 2m = -2/3

adell [148]

Answer:

$m = -\frac{4}{3}$

Step-by-step explanation:

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

Divide both sides by 2 to get just m

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

You can't divide a fraction by a number so you do kcf (keep it, change it, flip it)

$m = -\frac{2}{3} x \frac{2}{1}$

$m = -\frac{4}{3}$

Find the slope of the line passing through the pairs of points and describe the line as rising, falling, horizontal or vertical.

Anna [14]

Answer:

$a.\ m=2,\ \text{the line is rising}\\\\b.\ m=-\dfrac{5}{4},\ \text{the line is falling}\\\\c.\ m=0,\ \text{the line is horizontal}\\\\d.\ m\ is\ unde fined,\ \text{the line is vertical}$

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

m > 0, then a line is rising

m < 0, then a line is falling

m = 0, then a line is horizontal

m is undefined, then a line is vertical

(2, 1) and (4, 5)

$m=\dfrac{5-1}{4-2}=\dfrac{4}{2}=2>0\to\text{rising}$

(-1, 0) and (3, -5)

$m=\dfrac{-5-0}{3-(-1)}=\dfrac{-5}{4}=-\dfrac{5}{4}$

(2, 1) and (-3, 1)

$m=\dfrac{1-1}{-3-2}=\dfrac{0}{-5}=0\to\text{horizontal}$

(-1, 2) and (-1, -5)

$m=\dfrac{-5-2}{-1-(-1))}=\dfrac{-7}{0}\ \text{UNDEFINED}\to\text{vertical}$

F(x)=4x4−5x3−2x+6 and g(x)=3x3−4x2−2x+1 . What is f(x)+g(x) ?

igomit [66]

4*4-5*3-2x+6= -x-7/2 slope = 2

3 * 3 - 4 *2 -2x +1= - x - 2/2 slope = -2

2 + -2 = 0
