Answer:

210 ways

Step-by-step explanation:

In the question, the combination should be computed.

Number of ways of selection 6 flowers = nCr =10C6

                                           \frac{n!}{r!(n-r)!}  =\frac{10!}{ 6!(10-6)!}

                                                        =3628800/17280

                                                       =210

Therefore, there are 210 ways in which 6 flowers can be selected from the available 10 flowers.

If A=x² +xy-6, B=6xy-2x² +1 and C= 3x² +7 -3xy,find :(i) A+B+C​ (ii)A-B+C (iii)A+B-C​
Effectus [21]

Answer:

I)

\displaystyle A + B + C = 2x^2 + 4xy + 2

II)

\displaystyle A - B + C = 6x^2 -8xy

III)

\displaystyle A + B - C= -4x^2 + 10xy -12

Step-by-step explanation:

We are given the three equations:

\displaystyle A = x^2 + xy -6,\, B = 6xy - 2x^2  +1 \text{ and } C = 3x^2 + 7 -3xy

I)

We want to find:

\displaystyle A + B + C

Substitute:

\displaystyle = (x^2 + xy - 6) + (6xy -2x^2 + 1) + (3x^2 + 7 -3xy)

Rewrite:

\displaystyle = (x^2 + 3x^2 - 2x^2) + (xy + 6xy - 3xy) + (-6 + 1 + 7)

And combine like terms. Hence:

\displaystyle A + B + C = 2x^2 + 4xy + 2

II)

We want to find:

\displaystyle A - B + C

Likewise, substitute:

\displaystyle = (x^2 + xy - 6) - (6xy - 2x^2 + 1) + (3x^2 + 7 - 3xy)

Distribute:

\displaystyle = (x^2 + xy - 6) + (-6xy +2x^2 - 1) + (3x^2 + 7 - 3xy)

Rewrite:

\displaystyle = (x^2 + 2x^2 +3x^2) + (xy - 6xy -3xy) + (-6 -1 + 7 )

And combine like terms. Hence:

\displaystyle A - B + C = 6x^2 -8xy

III)

We want to find:

\displaystyle A + B - C

Substitute:

\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) - (3x^2 + 7 - 3xy)

Distribute:

\displaystyle = (x^2 + xy - 6) + (6xy - 2x^2 + 1) + (-3x^2 - 7 + 3xy)

Rewrite:

\displaystyle = (x^2 - 2x^2 - 3x^2) + (xy +6xy +3xy) + (-6 +1 - 7)

And combine like terms. Hence:

\displaystyle A + B - C= -4x^2 + 10xy -12

Determine the number of solutions the system of 1/3y-5=2x and y=3(2x+5)
lorasvet [3.4K]

Answer:

A. (4,1)

Step-by-step explanation:

2x -5y = 3

x -3y = 1

Change the equation to isolate a variable so you can substitute it in the other one.

x = 1+3y so

2(1+3y) -5y = 3

2 + 6y -5y =3

2 + y = 3

y=1

Back to the easy equation we isolated

x = 1+3(1)

x= 4

(4,1) is a point where x=4 and y=1
