I believe the answer is A
8.9 ÷ 6.497 = 1.370(rounded to the nearest thousandth)
Step-by-step explanation:
The domain is simply all of the x values of the relation. In this case, that is -1, 1, 3, and 6. The range is all of the y values. In this case, it is 2. Hope this helps!
Answer:
Yes It Is.
Step-by-step explanation:
Answer:
x = -1
y = 1
Step-by-step explanation:
y = -x² + 2 (1)
y = x² + 4x + 4 (2)
matching (2) and (1);
-x² + 2 = x² + 4x + 4
-x² - x² - 4x + 2 - 4 = 0
-2x² - 4x - 2 = 0
-x² - 2x - 1 = 0
x² + 2x + 1 = 0
(x + 1)² = 0
x + 1 = 0
x = -1
replacing in (1)
y = - x² + 2
y = - (-1)² + 2
y = -1 + 2
y = 1
Verification;
-x² + 2 = x² + 4x + 4
-(-1)² + 2 = (-1)² + 4(-1) +4
-1 + 2 = 1 - 4 + 4
1 = 1 ✔
