Answer:
(-2, -1)
Step-by-step explanation:
This is a quadratic equation in standard form, and a = 1, b = 4 and c = 3.
The x-coordinate of the vertex is given by the formula
-b -4
x = --------- which here has the numerical value x = -------- = -2
2a 2
Finally, we evaluate y=x^2+4x+3 at x = -2 to find the y-coordinate of the vertex:
y = (-2)^2 + 4(-2) + 3 = -1
The vertex is at (-2, -1).
Answer:
49%
Step-by-step explanation:
7 percent of 500=35%
Answer:
The point which is the midpoint is equally spaced from both ends of the line. We know the coordinates of A and we know the coordinates of M, the midpoint.
Step-by-step explanation:
That implies a simple multiplication, with a couple considerations:
17.5 percent = 17.5% = 17.5/100 = 175/1000
so we multiply both quantities:
17.5% of 2400
= (17.5%)(2400)
= (175/1000)<span>(2400)
</span>= 175*2400/1000
= 420
