A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3

Answer:
x = 0
Step-by-step explanation:
When there is no linear term in the equation, the axis of symmetry is x=0.
__
The values 'a' and 'c' represent a vertical scale factor and a vertical translation, respectively. They do not change the axis of symmetry from that of the parent function, which is x=0.
Answer:
250 times
Step-by-step explanation: This is because a number die is random and if it were based on even and odd, the chances would be 50/50
Step-by-step explanation:

ABD is the supplement of DBC, so it is equal to 180-130= 50 degrees.
If BE is the bisector, then it splits the angle in half evenly. 50/2=25 degrees for EBA and DBE each.
Final answer: 25 degrees
