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.
What is the slope if the equation is y equals 20x plus 40?
20
What is the x intercept of -20x plus y equals 35?
x = -1.75
X plus 52 plus y plus 72 equals 212?
54(x)+52+32(y)+72=212
Which expression can be used to solve for y in the equation 52 plus y equals 80?
subtraction; 80-y= 52. 28+52 =80
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)
-20x plus y equals 25?
... You have to know what x and y are first.
How do you solve 20x plus 5y equals 15?
If: 20x+5y = 15 Then: y = -4x+3
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.
What is the slope if the equation is y equals 20x plus 40?
20
What is 20x plus 80y equals 0 in y equals mx plus b?
20x + 80y = 0Subtract 20x from each side of the equation:80y = -20xDivide each side by 80:y = -1/4 xm = -1/4b = 0
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)
What is the x intercept of -20x plus y equals 35?
x = -1.75
How do you turn 20x plus 80y equals 0 into slope intercept form?
If: 20x+80y = 0 Then: 80y = -20x And: y = -0.25x So the slope is -0.25 and it has no y intercept
What are the points of intersection when the line y equals 10x -12 crosses the curve y equals x squared plus 20x plus 12?
If: y = 10x -12 and y = x^2 +20x +12 Then: x^2 +20x +12 = 10x -12 Transposing terms: x^2 +10x +24 = 0 Factorizing: (x+6)(x+4) = 0 => x = -6 or x = -4 Points of intersection by substitution are at: (-6, -72) and (-4, -52)
-20x 5y equals 40 changed to slope-intercept form?
If the equation is -20x-5y=40 then the answer is -5y=20x+40 which equals y=-4x-8 If the equation is -20x+5y=40 then the answer is 5y=20x+40 which equals y=4x+8
X plus 52 plus y plus 72 equals 212?
54(x)+52+32(y)+72=212
