What is Y equals 2x plus 5 in standard form?
2x+y=1
How do you rewrite this equation so that y is a function of x 2x plus y equals 5?
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
Y equals 2x y-x equals 5 using the sudstitution method?
-3
What is the point of contact when the tangent line y equals 2x touches the circle x2 plus y2 -8x -y plus 5 equals 0?
If: y = 2x then y² = 4x² If: x² + y² - 8x - y + 5 = 0 then x² + 4x² - 8x - 2x + 5 = 0 → 5x² - 10x + 5 = 0 → x² - 2x + 1 = 0 → (x - 1)² = 0 → x = 1 → y = 2x = 2 × 1 = 2 → point of contact is at (1, 2)
Solve 2x-y equals 1 2x plus 5y equals -5?
X = 0 (zero) Y = -1 (neg 1)
What is the answer to -2x y5?
-2x = y^5 or y^5 = -2x y = (-2x)^(1/5)
Does y equals 2x - 4 and y equals 2x - 5 have a common solution?
y=2x-4 y=2x-5 y=1 1=2x-4 -2x = -5 x=2/5 the solution is (x,y) = (2/5,1)
How do you simplify y equals 2x-5 and 4x-y equals 7?
y = 2x-5 4x-y = 7 => y = 4x-7 2x-5 = 4x-7 2x-4x = 5-7 -2x = -2 x = 1 Therefore by substituting: x = 1 and y = -3
What is Y equals 2x plus 5 in standard form?
2x+y=1
Y equals -2x2 plus 3x plus 5?
If you graph this it will be a parabola that has each end pointing down. It crosses the x-axis at: y=-2x^2+3x+5 y=-1(2x^2-3x-5) y=-1(2x-5)(x+1) y=5/2 y=-1
2x plus y equals 1 2x - y equals -5?
x= (-1/2)y-2.5
How do you rewrite this equation so that y is a function of x 2x plus y equals 5?
Solve for y.2x+y=5*subtract 2x from both sides*2x+y-2x=5-2xy=-2x+5 / y=5-2x
Y equals 2x y-x equals 5 using the sudstitution method?
-3
What is -1 from 2x - y?
2x - y -(-1) = 2x - y + 1
Factor 2x squared plus 2x plus xy plus y?
4
What is an equation of the line that passes through the point 3 1 and has a slope of 2?
y-1 = 2(x-3) y-1 = 2x-6 y = 2x-6+1 y = 2x-5
What is the point of contact when the tangent line y equals 2x touches the circle x2 plus y2 -8x -y plus 5 equals 0?
If: y = 2x then y² = 4x² If: x² + y² - 8x - y + 5 = 0 then x² + 4x² - 8x - 2x + 5 = 0 → 5x² - 10x + 5 = 0 → x² - 2x + 1 = 0 → (x - 1)² = 0 → x = 1 → y = 2x = 2 × 1 = 2 → point of contact is at (1, 2)
