X^2+4x-12=0
x^2-2x+6x-12=0
x(x-2)+6(x-2)=0
(x-2)(x+6)=0
x=-6 and 2
x= -13 , y=11
Step-by-step explanation:
Using elimination method, make the x variable equal to eliminate the variable
-3x - y = -28
2x+ 3y=7
2(-3x-y =28)
3(2x+3y=7)
-6x - 2y =56
6x +9y=21
Apply addition
7y = 77
y=77/7 = 11
Use the value of y=11 in
2x+ 3y=7
2x +3(11) =7
2x +33 =7
2x=7-33
2x= -26
x= -26/2 = -13

Hope this helps!!!!!!!
Binomial distribution because:
Trials are Bernoulli (affected or not)
Probability is known (p=0.05) and remains constant for all trials.
Number of trials is known (n=6).
P(x)=C(n,x)p^x*(1-p)^(n-x)
x=0 =>
P(0)=C(6,0)(0.05^0)(0.95^6)
=0.7351.... (approximately)
