What is the line of symmetry for the parabola whose equation is y equals -x2 plus x plus 3?
For a quadratic equation y=Ax2+Bx+C, the line of symmetry is given by x=-B/2ASo for the equation y=-x2+x+3, B is 1 and A is -1, so the line of symmetry isx=1/2
An equation of the axis of symmetry of the graph y equals -x2 plus 8x-7?
y = x2 + 8x - 7 a = 1, b = 8, c = -7 the equation of the axis of symmetry: x = -b/2a x = -8/(2*1) = -4
How do you find the slope and y intercept of y equals mx plus b?
The value of m is the slope and the value of b is the y intercept.
What is the slope in y equals mx plus b?
The graph of the equation is a straight line. 'm' is its slope. 'b' is its y-intercept
How do you find y equals mx plus b?
That depends on the values of m and b because it is the formula for a straight line equation whereas m is the slope and b is the y intercept
What is the x-coordinant of the vertex in the function y equals x2 plus 14 plus 21?
y = x2 + 14x + 21 a = 1, b = 14 x = -b/2a = -14/2*1 = -7
If a plus b plus c equals x plus y plus z then prove a2 plus b2 plus c2 equals x2 plus y2 plus z2?
a2+b2+c2=x2+y2+z2 divide each side by 2 (a2+b2+c2)/2=(x2+y2+z2)/2 a+b+c=x+y+z
What is the x coordinant of the vertex in the function y equals x2 plus 14 plus 21?
y = x2 + 14x + 21; a = 1, b = 14, c = 21 x-coordinate = -b/2a = -14/2 = -7 if it is y = x2 + 14 + 21, the x-coordinate is zero, since b = 0.
If 2 plus 2 equals x and x2 equals y and y-x equals a and a plus y equals b what is b?
in order to solve this problem you have to solve for x first wich you are given the data to pre forme so x=4 and x.2=8 and 8=y and y-4=4=a=x so a+8=12 and 12=b
In the linear equation is the variable for the y intercept b or c ie y equals mx plus b or y equals mx plus b?
in the equation: y=mx+b , the y-intercept is represented by "b".
If x equals a-b y equals b-c z equals c-a then the value of x plus y plus z x plus y plus z is?
x + y + z = 0 x = a - b, y = b - c, z = c - a, therefore a - b + b - c + c - a = ? a - a + b - b + c - c = 0
How would you work out A equals Y plus B if Y is the subject?
If: A = Y+B Then: -Y = -A+B or Y = A-B
What is the property of 4 equals x plus y then x plus y equals 4?
Symmetry, which states that if A = B then B = A Put A = 4 and B = x + y
An equation of the axis of symmetry of the graph y equals -x2 plus 8x-7?
y = x2 + 8x - 7 a = 1, b = 8, c = -7 the equation of the axis of symmetry: x = -b/2a x = -8/(2*1) = -4
What is the line of symmetry for the parabola whose equation is y equals -x2 plus x plus 3?
For a quadratic equation y=Ax2+Bx+C, the line of symmetry is given by x=-B/2ASo for the equation y=-x2+x+3, B is 1 and A is -1, so the line of symmetry isx=1/2
Is y equals mx plus b the same thing as y equals b plus mx or do you need to convert it?
same thing. but its easy to change y=b+mx to y=mx+b
What is the axis of symmetry for the function - y equals x squared plus 2x plus 1?
y=x2+2x+1 -b -2 2a= 2= -1 = axis of symmetry is negative one.
