Solve the given system using your choice of either graphically or algebraically. Show and explain all work. y + 2x = 2 y + 2 = 2x

x = 1 and y = 0

Step-by-step explanation:

Given equations are :

y + 2x = 2  (1)

y + 2 = 2x

or

y - 2x = -2 ...(2)

Add equation (1) and (2), we get :

y + 2x + y - 2x = 2 + (-2)

2y = 0

y = 0

Put the value of y in equation (1).

0 + 2x = 2

x = 1

Hence, the solution of the given equations are x = 1 and y = 0.

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.
