I is the square root of -1
The square root of -1 to the fourth power is 1.
Size got it right because it’s multiplied by 100
Answer:
The answer to your question is letter A. x = 0, y = 2/3
Step-by-step explanation:
Equation 1 2x + 3y = 2
Equation 2 x + 6y = 4
Solve the system of equations by elimination
- Multiply equation 2 by -2
2x + 3y = 2
-2( x + 6y = 4)
2x + 3y = 2
-2x - 12y = -8
0 - 9y = -6
y = -6/-9
y = 2/3
. Find x
2x + 3(2/3) = 2
2x + 2 = 2
2x = 2 - 2
2x = 0
x = 0/2
x = 0
Answer:
3x2y−3xy+12x−12
Take out 3xy common from first two terms and 12 from last two terms.
3xy(x−1)+12(x−1)
(x−1)(3xy+12)
