y + x = 9
10y + 20x = 100
This is a basic linear system of equalities. We can start by rewriting the first equation as:
-10y - 10x = -90 by multiplying the equation by -10, from here we can eliminate y and solve for x
(-10y - 10x = -90) + (10y + 20x = 100) = (10x = 10)
This yields x = 1, and by plugging x into the first equation y = 8
What else can I help you with?
Where do the parabolas of y equals x squared plus 20x plus 100 and y equals x squared minus 20x plus 100 meet on the x and y axis?
They touch each other at (0, 100) on the x and y axis.
X2 plus 20x plus 4 equals 0?
x2 + 20x + 4 = 0 x2 + 20x + 100 = 96 (x + 10)2 = 96 x + 10 = ±961/2 x = -10 ±961/2 x = -10 ±4√6

What is the point of intersection of the parabolas y equals x2 plus 20x plus 100 and y equals x2 -20x plus 100 showing work?
If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
What is the point of contact between the curves of y equals x squared plus 20x plus 100 and y equals x squared -20x plus 100?
The graphs of the two equations will intersect when x² + 20x + 100 = y = x² - 20x + 100 Subtracting x² +100 from both sides you get 20x = -20x that will only be true when x = 0. At x = 0, y = 100 for both equations - so the point of contact would be (0,100)
Where do the parabolas of y equals x squared plus 20x plus 100 and y equals x squared minus 20x plus 100 meet on the x and y axis?
They touch each other at (0, 100) on the x and y axis.
