Determine the best method to solve the system of equations. then solve the system.
7x-2y=8
5x+2y=4

x=1  y = -1/2

(1,-1/2)

Step-by-step explanation:

7x-2y=8  

5x+2y=4

I would use elimination since we have 2y in one equation and -2y in the other

7x-2y=8  

5x+2y=4

12x = 12

Divide each side by 12

12x/12 = 12/12

x =1

The substitute back into equation 2

5(1) +2y = 4

5 +2y = 4

Subtract 5

5-5+2y = 4-5

2y = -1

Divide by 2

2y/2 = -1/2

y = -1/2

The best method is the elimination method. The solution is (1, -1/2).

Step-by-step explanation:

7x - 2y = 8

5x + 2y = 4

12x = 12

x = 1

7(1) - 2y = 8

7 - 2y = 8

-2y = 1

y = -1/2

Make sure to write the answer in the form of an ordered pair.

Note: Alternative methods are graphing and the substitution method.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

answer: 2 answers

step-by-step explanation: the first one means to spread the product throughout the marketplace such that a large number of people can buy it.
