The ordered pairs (1, 25), (2, 36), (3, 49), (4, 64), and (5, 81) represent a fixnction. what is a rule that represents this fun

nlexa [21]

By inspection we can see that <span>(1, 25), (2, 36), (3, 49), (4, 64), and (5, 81)

$(1,\ 5^2),\ (2,\ 6^2),\ (3,\ 7^2),\ (4,\ 8^2),\ and\ (5,\ 9^2) \\ \\ =(1,\ (1+4)^2),\ (2,\ (2+4)^2),\ (3,\ (3+4)^2),\ (4,\ (4+4)^2),\ \\ and\ (5,\ (5+4)^2)$

Therefore, the rule that represents this function is $y=(x+4)^2$ .</span>

Determine whether the ordered pair is a solution to the inequality. (-1, -1); y Greaterthanorequalto - x + 7 (5, 3); y > 3/4

Art [367]

Answer:

No and Yes.

Step-by-step explanation:

The inequation is y ≥-x+7 and the pair is (x,y)=(-1,-1). Then:

-1≥ -(-1)+7

-1 ≥ 1+7

-1 ≥ 8, but this is not true, so (-1,-1) is not a solution of y ≥-x+7.

On the other hand, the inequation is y>(3/4)x-5 and the pair is (5,3). Then:

3>(3/4)(5)-5

3>(15/4)-5

3> -5/4 and this is true, so (5,3) is a solution of y>(3/4)x-5.
