Use substitution to solve the linear system of equations
xenn [34]

we are given

system of equations

y=4x

3x+5y=-46

we can plug first equation into second equation

we get

3x+5(4x)=-46

Simplify left side

3x+20x=-46

23x=-46

Divide both sides by 23

and we get

x=-2

now, we can find y-value

y=4*-2

y=-8

so, our solution is

(x,y)=(-2,-8).............Answer

A pair of dice is rolled, and the sum of the numbers is either 7 or 11. What is the probability of this event?
AfilCa [17]

Answer:   \dfrac{2}{9}

Step-by-step explanation:

Let A be the event that the sum is 7 and and B be the event that the sum is 11 .

When two pair of dices rolled the total number of outcomes = n(S)=6\times6=36

The sample space of event A ={(1,6), (6,1), (5,2), (2,5), (4,3), (3,4)}

Thus n(A)= 6

The sample space of event B = {(5,6), (6,5)}

n(B)=2

Since , both the events are independent , then the required probability is given by :-

P(A\cup B)=P(A)+P(B)\\\\=\dfrac{n(A)}{n(S)}+\dfrac{n(B)}{n(S)}=\dfrac{6}{36}+\dfrac{2}{36}=\dfrac{8}{36}=\dfrac{2}{9}

Hence, the required probability = \dfrac{2}{9}
