The answer is A. The negative sign out front flips the function upside down (over the x axis), the +1 inside the parenthesis shifts it to the left one unit and the -5 moves it down 5 units.
The sum of two numbers is addition + but the rest is good (by the way its right not write but that's ok )
Answer:
15x + 24y <= 120
Step-by-step explanation:
It takes 15 minutes per oil change, 15x
It takes 24 minutes per tire change, 24y
In at most 120 minutes, so it must be less than or equal to the time available.
We are asked to create a factorable polynomial that has a GCF of 3x. This can be done in many different ways, but we'll use the easiest one. This will be completing the square.
GCF: 3x
Suitable Polynomial: 3x³ + 18x² +27x
Other Expressible Ways:
1) 3x(x² + 6x + 9)
2) 3x(x + 3)²
We got this by creating a perfect trinomial, which is x² + 6x + 9, as it can be factored into the binomial (x + 3)². All we had to do is multiply 3x to x² + 6x + 9 and simplify. Hope this helped!
