Step-by-step explanation:
2x - 3y = 9
2x + 3y = 3
__________ -
-6y = 6
y = -1
2x - 3y = 9
2x - 3(-1) = 9
2x - (-3) = 9
2x = 12
x = 6
The answer is A because if you do the 40 dagree and a coodinate plane it forms a triangle.
Answer: 0.970 ??
Step-by-step explanation:
Answer:

Step-by-step explanation:
Whe have the function 
To solve this equation we must factor.
To factor, we need to find the points where the function is equal to zero. So we use the quadratic formula

Where:
a = 3
b = -6
c = 2
Then

finally the correct answer is 
Answer:
216
Step-by-step explanation:
9 * 6 = 54
54 * 8 = 432
432/2 = 216 is the answer
