Answer:
Step-by-step explanation:
- y² - 10y + 30 =
- y² - 10y + 25 + 5 =
- (y - 5)² + 5
<u>Since (y - 5)² ≥ 0, the expression above is positve:</u>
I believe the answer 12p^2
Answer:
B
Step-by-step explanation:
Choose any point and put it into one of the choices of equations. Let's just do (4, 2):
A) y = 2x ⇒ 2 =? 2 * 4 ⇒ 2 ≠ 8 --- eliminate
B) y =1/2x ⇒ 2 =? 4 * (1/2) ⇒ 2 = 2 --- correct; keep it
C) y = 1/2 + x ⇒ 2 =? 1/2 + 4 ⇒ 2 ≠ 4.5 --- eliminate
D) y = 2 + x ⇒ 2 =? 2 + 4 ⇒ 2 ≠ 6 --- eliminate
Thus, B is the correct answer.
Hope this helps!
