Answer:
2
Step-by-step explanation:
F(3) means that we plug in 3 for the x value of the original equation, and F(4) means that we plug in 4 for the x value of the original equation
F(3) = -2(3) + 3
= -3
F(4) = -2(4) + 3
= -5
- 3 -(-5) = 2
Each small doll cost 6.5 dollars and each large doll cost 10 dollars
Try to get all your like terms to the same side. for example get all your x values to the left side and all your number values to the right side.
5 + 2x = 8x - 4
2x - 8x = - 4 - 5
-6x = -9
x = -9/-6
x = 1.5 or 1 1/2
hope this helps and have a great day! :)
