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:
DEF = 110
Step-by-step explanation:
Supplementary angles add to 180
3x+5 +2x = 180
Combine like terms
5x +5 = 180
Subtract 5 from each side
5x = 175
Divide each side by 5
5x/5 = 175/5
x =35
DEF = 3x+5
= 3*35 +5
= 105+5
= 110
Answer:
x²+11x+28
Step-by-step explanation:
(f - g) (x) = f(x) - g(x)
x² + 12x + 32 - (x + 4) = x² + 11x + 28
It would be the negative form of those bumbers and the non-negative form of those numbers. The absolute value applies to negative numbers the same. For example absolute value of -3 is 3.
