Subtract "this" from "that" ⇒ "that" - ("this")
12x² + 3xy - 5y² - (8x²  + 3xy + 4y²)
12x² + 3xy - 5y² + -8x² - 3xy - 4y²        Subtraction means add the opposite
Now Combine like terms:
12x² - 8x² = 4x²
3xy - 3xy = 0
-5y² - 4y² = -9y²
ANSWER: 4x
² - 9y²

Which answers describe the end behaviors of the function modeled by the graph? f(x)=4 1/3x+3 , Select each correct answer.
bezimeni [28]

Answer:

As x decreases without bound, f(x) approaches the line y=3 .

As x increases without bound, f(x) increases without bound.

Step-by-step explanation:

From the given graph f(x), we can see that

When x  increases the value of y also increases

When x decreases  the y values goes close to 3 but it does not cross 3

As x goes to positive infinity , y approaches positive infinity

As x increases without bound, f(x) increases without bound.

As x goes to negative infinity, y values approaches +3

As x decreases without bound, f(x) approaches the line y=3

MrRissso [65]

Answer:

8 hours long

Step-by-step explanation:

3/4 of the race in 6 hrs  

6 divided by 3 equals 2  

so 1/4 is 2 hrs, 2/4 is 4 hrs, 3/4 is 6 hrs which means 4/4 the whole race would be 8 hrs  

4 multiplied by 2 would give you 8  

so the entire race was (8 hours long)
