Use the substitution method to solve the system of equations Choose the correct ordered pair?
2x+7y=29 x=37-8y
What are the factors of x2 - y4?
-2
How do you use absolute value to find the distance between two points that have the same x coordinates but different y coordinates?
The distance between (x, y1) and (x, y2) is abs(y1 - y2) or |y1 - y2|.
When solving by the substitution method what happens when one variable cancels out?
That's exactly the purpose of the substitution method ... to get an equation with one less variable. When you have it, you solve it for the variable that's left.
How do you factor x2- y2?

What is y to the 8th power as an product in four different was with only positive exponents?
y6 x y2 y4 x y4 y2 x y2 x y4 y2 x y2 x y2 x y2
Solve the equation by substitution method x-y equals 5?
x+y=5
Use the substitution method to solve the system of equations Enter your answer as an ordered pair?
Use the substitution method to solve the system of equations. Enter your answer as an ordered pair.y = 2x + 5 x = 1
How do you solve (x y2)(x-y2)?
0
Which technique of differentiation does the substitution method attempt to undo?
The substitution method undoes the chain rule.
Is this a function x equals y2?
Yes, as x-y2=0
Solve this using substitution x plus 2y equals 30 x2 plus y2 equals 900?
x+2y = 30 => x= 30-2y x2+y2 =900 (30-2y)2+y2 = 900 (30-2y)(30-2y)+y2 = 900 900-60y-60y+4y2+y2 = 900 5y2-120y = 0 y(5y-120) = 0 y = 0 or y= 24 Substitute the value of y into the original equations to find the value of x: Therefore: x = -18 and y = 24 Check: -18+48 = 30 and (-18)2+242 = 900
What is y6x plus 11 y2x plus 7 in substitution method?
If you mean: y = 6x+11 and y = 2x+7 Then by substitution: x = -1 and y = 5
Substitution method 2x plus 3y equals 13 x equals 2?
2x-3y=13
What is the answer to (x plus y)2 x2 plus y2?
X2+y2=25 (x-8)2+y2 =41
How do you solve x plus y equals 4 and y equals 2X plus 1 by substitution method?
If: x+y = 4 and y = 2x+1 Then: 4-x = 2x+1 => 3 = 3x => 1 = x So by substitution: x = 1 and y = 3
Convert x2 plus y2 equals 2x?
What do you want to convert it to? x2 + y2 = 2x If you want to solve for y: x2 + y2 = 2x ∴ y2 = 2x - x2 ∴ y = (2x - x2)1/2 If you want to solve for x: x2 + y2 = 2x ∴ x2 - 2x = -y2 ∴ x2 - 2x + 1 = 1 - y2 ∴ (x - 1)2 = 1 - y2 ∴ x - 1 = ±(1 - y2)1/2 ∴ x = 1 ± (1 - y2)1/2
