The sum of the terms in a row in Pascals Triangle follows the rule Sᵣ = 2ʳ. Where S is the sum, and r the rᵗʰ row. Use the formula to find the sum of the terms in the tenth row.

1024

Step-by-step explanation:

For the 10th row, r = 10.

The answer is:  [C]:   "  y < x² − 4 " ;   " y > x² + 3 " .
 

We see on the graph that "(0, -5)" is NOT a solution;  

so we can eliminate choices [A] & [B]:  . 

We know that "y < x² − 4" is one of the equations.

We know that "(0, 5)" is a solution to the other equation (shaded in blue); which leaves us with:  

Answer choice:  [C]:   "  y < x² − 4 " ;   " y > x² + 3 " .
