260 I believe. Start from the end...
170-80=90
90*2=180
180-50=130
130*2=260

Answer:
The answer is B) 11.
Step-by-step explanation:
We can solve this by making an expression to represent the situation. Let x = the number of student books in the box (what we're looking for):






Answer:
y is NOT a function.
Step-by-step explanation:
The equation given to us is:
x² + 3y² = 3
Rearrange the equation:
3y² = 3 - x²
y² = (3 - x²)/3
y² = 1 - (x²)/3
y = ±√(1 - x²/3)
For any equation to be a function, there should be only one output for one input. Which means that for any value of x, there should be only one value of y. However, in this equation, as the underroot gives two values of any terms under it, it shows that if we put any value of x, we'll get 2 values of y. Therefore, y is not a function.
