Are the linear equation in standard form? sort each equation into the appropriate category.

The Standard Form for a linear equation in two variables, x and y, is usually given as Ax + By = C.

Step-by-step explanation:

So the 3rd 4th 5th and 6th.

Answer

Standard form: 2x + y = -1 , x = 3

Not Standard form: y = 3x - 5, -x - y = 9, 2.7x + 4.1y = -6.8, 8y - 5 = x

Step-by-step explanation:

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
