Answer:
, or in this case, 
Step-by-step explanation:
Assuming that Justine's score is represented by 
and Meagan's score is represented by 
, we know that will always be the opposite of .
To represent opposite, we put a negative sign before the variable.
This makes the current number, even if it's negative, the opposite value.
Let's test it out.
Since Justine's score is -7, substituting it into the equation makes it . We know that two negatives make a positive, so 
.
Now let's assume Justine's score is 7. Plugging it into the equation, we get 
. That's the same thing as 
, and -1 times 7 is -7.
Hope this helped!
Answer:
3+x sqrt 7 -13 is a radical equation.
Answer:
Option B. The equation has a maximum value with a y-coordinate of -21.
Step-by-step explanation:
The correct quadratic equation is
This is a vertical parabola open downward (the leading coefficient is negative)
The vertex represent a maximum
Convert to vertex form
Factor -3
Complete the square
Rewrite as perfect squares
The vertex is the point (2,-21)
therefore
The equation has a maximum value with a y-coordinate of -21
