Answer:
(-4, -3), (4, -1), (8, 0), (12, 1)
Step-by-step explanation:
The x- and corresponding y-values are listed in the table. Put each pair in parentheses, <em>x-value first</em>. (That is an <em>ordered pair</em>.)
(x, y) = (-4, -3) . . . . from the first table entry
(x, y) = (4, -1) . . . . from the second table entry
(x, y) = (8, 0) . . . . from the third table entry
(x, y) = (12, 1) . . . . from the last table entry
Add -11 and 15 to get 4
x^2 + 4
Answer:

X=0.69
Answer:
Let D represent the average rate of change between 1990 and 1999
D ≈ 33%
Step-by-step explanation:
412+412×(D÷100 )= 549
⇔ 412×(D÷100) = 549 - 412
⇔ 412×(D÷100) = 137
⇔ D÷100 = 137÷412
⇔ D÷100 = 0.332524271845
⇔ D = 33.2524271845.
