1 answer:

6 0

Step-by-step explanation:

Examples of categorical variables are race, genders, ages, and education levels. While the closing two variables may be considered in a numerical manner by using exact values for age and the high grade completed, it is always informative to put such variables into a relatively small number of groups.

2x + 12 = 1/3 (7/3x+4/3)

gladu [14]

Answer:

Step-by-step explanation:

2x + 12 = 1/3 (7/3x+4/3)

$2x+12=\frac{1}{3}*\frac{7x}{3}+\frac{1}{3}*\frac{4}{3}\\\\2x+12=\frac{7x}{9}+\frac{4}{9}\\\\2x-\frac{7x}{9}=\frac{4}{9}-12\\\\\frac{2x*9}{1*9}-\frac{7x}{9}=\frac{4}{9}-\frac{12*9}{1*9}\\\\\frac{18x}{9}-\frac{7x}{9}=\frac{4}{9}-\frac{108}{9}\\\\\frac{18x-7x}{9}=\frac{4-108}{9}\\\\\frac{11x}{9}=\frac{-104}{9}\\\\\\x=\frac{-104*9}{11*9}=\frac{-104}{11}=-9\frac{5}{11}$

What is the slope of the line? 3x-4y=73x−4y=7

Andrei [34K]

To find the slope, we put this in y = mx + b form where m is ur slope.

3x - 4y = 7.....subtract 3x from both sides
-4y = -3x + 7 ...now we divide both sides by -4
(-4/-4)y = (-3/-4)x + (-7/4)...simplify
y = 3/4x - 7/4

y = mx + b
y = 3/4x - 7/4.....so the number in the m position is 3/4 <== ur slope
