Answer:

a) m + n + e3 + ( -2n)  +  10m  =  11m - n + e3

b) x + 2y -4y + 6x + 2x = 9x -2y

c) a + b + c + 2a + 3c -2a + 3b + 4c = a + 4b + 8c

d) 2a  -b + 3c -2a + 3b + 2c = 2b + 5c

Step-by-step explanation:

En cada uno de los casos:

1) Reorganizas los términos

2) sumas los coeficientes de los términos semejantes

a)  m + n + e3 + ( -2n)  +  10m

1)<u> Reorganizando los términos</u>

m + 10m + n + ( -2n)  + e3

2) <u>Sumando los coeficientes de los términos semejantes</u>

(1 + 10) m + (1 - 2) n + e3

(11)m + (-1)n + e3

11m - n + e3

__________________

b)  x + 2y - 4y + 6x + 2x

1)<u> Reorganizando los términos</u>

x + 6x +2x + 2y - 4y

2) <u>Sumando los coeficientes de los términos semejantes</u>

(1 +6 +2) x + (2- 4) y

(9) x + (-2)y

9x -2y

__________________

c)  a + b + c + 2a + 3c -2a + 3b + 4c

1)<u> Reorganizando los términos</u>

a + 2a - 2a  + b + 3b + c + 3c + 4c

2) <u>Sumando los coeficientes de los términos semejantes</u>

(1 + 2 - 2 ) a + (1  +3) b + ( 1 + 3 +4) c

(1) a + (4)b + (8)c

a +4b + 8c

__________________

d)  2a -b + 3c -2a + 3b + 2c

1)<u> Reorganizando los términos</u>

2a - 2a - b + 3b + 3c +2c

2) <u>Sumando los coeficientes de los términos semejantes</u>

(2 - 2) a + (-1 +3) b + (3 +2)c

(0) a + (2) b + (5) c

2b + 5c

Consider the line y=1 x -1 and the point P=(2,0).
Montano1993 [528]

Answer:

Step-by-step explanation:

d(x)=√((x-2)2+(y-0)²)

=√((x-2)²+y²)

=√((x-2)²+(x-1)²)

=√(x²-4x+4+x²-2x+1)

=√(2x²-6x+5)

D=d²(x)=2x²-6x+5

b.\\\frac{dD}{dx}=4x-6\\\frac{dD}{dx}=0,gives \\4x-6=0\\x=\frac{3}{2}\\\frac{d^2D}{dx^2}=4 >0 at x=\frac{3}{2}\\so~D~or~d^2~or~d~is~minimum~at~x=\frac{3}{2}\\so~y=1(\frac{3}{2} )-1=1/2=0.5\\so~nearest~point~is~(1.5,0.5)

what is the probability of drawing two yellow marbles if the first on is NOT place back into the bag before the second draw?
Kruka [31]

Answer:

1/45

Step-by-step explanation:

I assume there are 10 marbles total, 2 of which are yellow.

The probability the first marble is yellow is 2/10.

There's now one less marble, so the probability that the second marble is yellow is 1/9.

The total probability is (2/10) (1/9) = 1/45.
