A graph shows the x-intercepts to be x ∈ {1, 4, 7}.
These are the real solutions to the equation.
Answer:
Each witch is 15
Each broom is 7
Each spoon is 4
So when you take the broom and spoon off of the witch that makes the witch worth 4
Apply rules of math

4+28
32
Rise/Run, so it rises 20, it runs 3, so it is 20/3, or 6 2/3.
Answer:
42x-27
Step-by-step explanation:
7(6x-4)+1 is your original expression. Distribute to get 42x - 28 + 1. Combine like terms and add 1 to -28, which is -27. So, 42x-27 is your answer.
