Answer:
No, it is incorrect.
Step-by-step explanation:
The quadratic equation is
or 
. To complete square we take the coefficient of x divided by 2, square that value and add the result to both sides. In the equation given the number to do the process is 20, not 6, then the solution method is incorect.
Answer:
umm what
Step-by-step explanation:
Answer:
a) a quadrilateral that is not a parallelogram because adding the same will make it a diamond like shape which 2 sides are parallel

Answer: B not sure if I’m right though .
Step-by-step explanation:
Answer:
Then the desired equation is y = -2x - 6.
Step-by-step explanation:
As we move from point (-3, 0) to point (0, -6), x increases by 3 and y decreases by 6. Thus, the slope of the line segment connecting these two points is m = rise / run = -6/3 = -2.
Now use the slope-intercept equation of a straight line to determine the y-intercept of this line:
y = mx + b becomes 0 = -2(-3) + b, so that b = -6.
Then the desired equation is y = -2x - 6.
Check: Does (0, -6) satisfy y = -2x - 6? Is -6 = -2(0) - 6 true? YES
