Answer:

y = 11

Step-by-step explanation:

Solve for y

12y - 40 - 4y = 6y - 18

8y -40 = 6y - 18

8y - 6y - 40 = -18

2y - 40 = -18 ( the justification for step 2 is to isolate y on one side of the equation in order to solve for y )

2y - 40 + 40 = 40 - 18

2y = 22

2y/2 = 22/2

y = 11

Check :

12(11) - 40 - 4(11) = 6 (11) - 18

132 - 40 - 44 = 66 - 18

48= 48

Answer:

x2 = -0.600000

x3 = -0.521600

Step-by-step explanation:

Given the formula;

xn+1 = (xn)³-5/10

x2 = (x1)³-5/10

Given x1 = -1

x2 = (-1)³-5/10

x2 = (-1-5)/10

x2 = -6/10

x2 = -0.600000

x3 = (x3)³-5/10

Given x3 = -0.6

x3 = (-0.6)³-5/10

x3 = (-0.216-5)/10

x3 = -5.216/10

x3 = -0.521600

butalik [34]

we are given

A presidential candidate plans to begin her campaign by visiting the capitals in 4 of 47 states

so, the number of ways of selecting four specific capitals out of 47 states is

$=47C_4$

$=\frac{47!}{4!(47-4)!}$

$=178365$

now, we can find probability

so, the probability is

$=\frac{1}{178365}$ ..............Answer
