Answer: The correct answer would be -85.
Step-by-step explanation: This is because the -5 becomes positive because it is inside parentheses.
This would make the expression: -425 ÷ 5.
-425 ÷ 5 is equal to -85.
Hope this helps and have a nice day! :)
4) n=12 this is because 45/4=11.25 and dividing 135 by 11.25 equals to 12
5) n=2.5 this is because 5/2=2.5 and multiplying 1 by 2.5 equals to 2.5
hope this helps :)
Answer:Exact Form:
1/2
Step-by-step explanation:
From the problem, the vertex = (0, 0) and the focus = (0, 3)
From the attached graphic, the equation can be expressed as:
(x -h)^2 = 4p (y -k)
where (h, k) are the (x, y) values of the vertex (0, 0)
The "p" value is the difference between the "y" value of the focus and the "y" value of the vertex.
p = 3 -0
p = 3
So, we form the equation
(x -0)^2 = 4 * 3 (y -0)
x^2 = 12y
To put this in proper quadratic equation form, we divide both sides by 12
y = x^2 / 12
