14 because it is half of the width around the pond.
X= 3 to x = 4 has a greater rate of change
Remember that a quadratic equation is a parabola. The equation is of the type y = Ax^2 + Bx + C
A linear equation is a straight line. The equation is of the type y = MX + N
The soluction of that system is Ax^2 + Bx + C = MX + N
=> Ax^2 + (B-M)x + (C-N) = 0
That is a quadratic equation.
A quadratic equation may have 0, 1 or 2 real solutions. Those are all the possibilitis.
So you must select 0, 1 and 2.
You can also get to that conclusion if you draw a parabola and figure out now many point of it you can intersect with a straight line.
You will realize that depending of the straight line position it can intersect the parabola in none point, or one point or two points.
-18- -27 = -45 -45- -15 = -30
Answer:
c = 2
Step-by-step explanation:
6 = 6c-6
+6 +6
12 = 6c
12 / 6 = 2
