x + 7 = 2(3x - 4)         Remove the brackets

x + 7 = 2*3x - 4*2

x + 7 = 6x -  8            Subtract 7 from both sides.

x + 7 - 7 = 6x - 8 - 7  

x = 6x - 15                 Subtract 6x from both sides

x - 6x = - 15

-5x = - 15                   Divide by -5

-5x/-5 = -15/-5

x = 3

A box contains 10 balls, of which 3 are red, 2 are yellow, and 5 are blue. Five balls are randomly selected with replacement. Ca
VLD [36.1K]

Answer:

The required probability is 0.1.

Step-by-step explanation:

red balls = 3

yellow balls =  2

blue balls = 5

Selected balls = 5

Number of elemnets in sample space = 10 C 5 = 1260

Ways to choose 1 red ball and 4 other colours =  (3 C 1 ) x (7 C 4) = 105

Ways to choose 5 balls of other colours = 7 C 5 = 21

So, the probability is

\frac{105}{1260} + \frac {21}{1260}\\\\\frac{126}{1260}=0.1

How do you the equation of the line that passes through x-intercept (–8, 0) and undefined slope?
kifflom [539]
If the slope is undefined, then your line is a vertical line since vertical lines can have no slope (they don't have any lateral movement). Because it must pass through (- 8, 0), x must = - 8.

Your equation is x = - 8
