Answer:

x=2

Step-by-step explanation:

add like terms (3x-9x= -6x, 7-3= 4)
then move the constant to the right (-8+4=-12)
finally divide it by 6 which gives you "x"

A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv

Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. $P(Red) = 0.4375$

b. $P(White) = 0.3125$

Step-by-step explanation:

Given

$Red = 7$

$White = 5$

$Yellow = 4$

First, we need to calculate the total

$Total = Red + White + Yellow$

$Total = 7+5+4$

$Total = 16$

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{7}{16}$

$P(Red) = 0.4375$

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

$P(White) = \frac{White}{Total}$

$P(White) = \frac{5}{16}$

$P(White) = 0.3125$

Determine the slope-intercept form of the equation of the line parallel to y = x + 11 that passes through the point (–6, 2). y =

Vika [28.1K]

Answer:

$y = x+12$

Step-by-step explanation:

Parallel => This means it has the same slope as this one.

Slope = m = 1

Now,

Point = (x,y) = (-6,2)

So, x = -6, y = 2

Putting this in slope intercept form to get b

$y = mx+b$

=> 2 = (1)(-6) + b

=> b = 2+6

=> b = 8

Now putting m and b in the slope-intercept form to get the required equation:

=> $y = mx+b$

=> $y = x+12$
