Nina knows that the average of the x-intercepts represents the line of symmetry for a quadratic function through the x-axis
Which equation represents the average of the x-intercepts for x) = 4x2-24x + 207

Is this a polynomial function? i need to know asap

The equation line of cd is y=-2x-2. write an equation of a line parallels to line cd in slope-intercept form that contains point (4,5)

Consider the equation 0.2(x – 4.5) + 1.7 = 9.6. 1. use the distribution property. 2. combine like terms. 3. use the properties of equality and inverse operations to isolate the variable. 0.2x + (-0.9) + 1.7 = 9.6 0.2x + 0.8 = 9.6
