bija089 [108]

Answer:

z = -16

Option c

Step-by-step explanation:

2= 10+z / -3

Multiply both sides by -3

2×-3 = 10 + z

-6 = 10 + z

Subtract 10 from both sides

-6 -10 = 10-10 + z

-16 = z

z = -16

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>
