Answer:
x = -8
Step-by-step explanation:
Set the function f(x)=9-2x equal to 25, and then solve the resulting equation for x:
9 - 2x = 25.
Isolate the -2x term by subracting 9 from both sides:
-2x = 16
Finally, solve for x by dividing both sides by -2:
x = -16/2, or x = -8
Answer:
-6r - 2s
Step-by-step explanation:
Combining Like Terms like this
-4r + s-2r - 3 s <<<
-6r + s - 3 s
= -6r - 2s <<<

We know some facts:
- x for the original price.
- The store has a coupon for $10 off and a discount of 20%
- C for the price after the coupon is applied.
So from the statement 2, you can realize there are two types of discounts:
- The discount offered by the coupon
- The discount offered by 20%
Since we need to write a function just for the coupon, then we don't include the discount offered as percentage, then we subtract the coupon from the original price:

Tree C is the proper tree. The first game has the possibility of a win, a loss, or a tie which the first row represents. The second game could also win, lose or tie, meaning each result would have each possibilty for that game.
