7/9 - 4/3w = -5/6 what is w

borishaifa [10]

Answer:

w=1 5/24

Step-by-step explanation:

7/9-4/3w=-5/6

-4/3w=-5/6-7/9

-4/3w=-15/18-14/18

-4/3w=-29/18

w=-29/18:(-4/3)

w=29/18*(3/4)

w=29*3/18*4

w=29/6*4

w=29/24

w=1 5/24

Consider the line through (-1, -4) and (1, 2). What is the slope (m) of the line?

zloy xaker [14]

Answer:

3

Explanation:

$\bold{\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(-1,\:-4\right),\:\left(x_2,\:y_2\right)=\left(1,\:2\right)}$

$\bold{m=\frac{2-\left(-4\right)}{1-\left(-1\right)}}$
