The table can be used to determine the solution of equations, 2x − 2y = 6 and 4x + 4y = 28.
natta225 [31]

we have

2x-2y=6 ------> equation 1

4x+4y=28 ------> equation 2

Multiply by 2 the equation 1

4x-4y=12 ------> equation 3

Sum equation 2 and equation 3

4x+4y=28\\ 4x-4y=12\\ ------\\ 8x=40\\ x=40/8\\ x=5

Substitute the value of x in the equation 2

4x+4y=28

4*5+4y=28\\ 4y=28-20\\ 4y=8\\ y=8/4\\y=2

therefore

the answer is the option B

Find the discriminant for the following equation 3x^2+4x=2
hichkok12 [17]

Answer:

The discriminant is 40

Step-by-step explanation:

First, rewrite the equation as 3x^2+4x-2=0 so that the equation is in the form of ax^2+bx+c=0. Thus, the discriminant is b^2-4ac=(4)^2-4(3)(-2)=16+24=40. This tells us that since the discriminant is greater than 0, then there are 2 real solutions.
