The root is the x intercepts or the zeros of the problem

If I were to graph

(x-5)(x+4)=0

We need a number for x which makes this equation 0

The numbers are 5 or -4

These are the x intercepts of the parabola or roots

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Step-by-step explanation:

If x varies inversely as y, and x = 11 when y = 15, find x when y = 3.
MaRussiya [10]

Answer:

x = 55

Step-by-step explanation:

given x varies inversely as x then the equation relating them is

x = \frac{k}{y} ← k is the constant of variation

to find k use the given condition x = 11 when y = 3

k = xy = 11 × 15 = 165

x = \frac{165}{y} ← variation equation

when y = 3, then

x = \frac{165}{3} = 55
