Y(y + 4) - y 2 = 6 is a quadratic equation. true false

False.

Step-by-step explanation:

y(y + 4) - y 2 = 6

y^2 + 4y - y^2 = 6

The y^2's  disappear.

4y = 6  which is a linear equation.

its True

Step-by-step explanation:

y2 +3y - 6=0

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
