Sandra sale de su casa y camina 8 metros a la derecha, luego 5 metros a la izquierda, luego 7 metros a la izquierda, luego 6 metros a la derecha, luego 1 metro a la derecha, luego 4 metros a la izquierda, 2 metros a la derecha, y por ultimo 5 metros a la izquierda. ¿En qué posición queda ubicada Sandra después de su ultimo desplazamiento?

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
