I’m assuming you mean -1/4 -4, and since you’re subtracting a negative by a negative, it would be -4 1/4(mixed number)
Answer:
its an equallateral so its 60 degrees
Step-by-step explanation:
Vertex form: y = a(x - h)² + k
h = 2
k = -1
y = 0
x = 5
0 = a(5 - 2)² - 1
0 = 9a - 1
a = 1/9
The answer is A. If you divide 3/8 which equals .375. Then you multiply .375 by 6 to get 2.25!
:D Hope this helps!
Answer:
-9
Step-by-step explanation:
