y equals 4x+1 is a parallel line to y equals 4x.
It is: y = -4x+12
Yes, y = 4x + 7 is a linear equation.
Because when your solving a quadratic equation your looking for x-intercepts which is where why equals 0 and x equals what ever the answer is.
None because the discriminant of this quadratic equation is less than zero.
-4
Then the straight line equation is: y = -4x+6
Yes, y = -4x + 3 is a linear equation.
-x2-4x+1 when y = 0Factorise the expression in the equation by using the quadratic equation formula:(-x-4.2360679775)(x-0.2360679775)So: x = 4.2360679775 or x = 0.2360679775Check that your answer is correct by multiplying out the brackets which will take you back to -x2-4x+1 = 0.When working out this type of quadratic equation remember the rules governing the minus signs in multiplication and division.
y = x2 - 4x + 3y = x -1Substitute the 2nd equation into the firstx -1 = x2 -4x + 3Rearranging:x2 -4x -x +3 +1 = 0x2 - 5x +4 = 0Solving this quadratic equation in x by factorising gives 2 values for xx1 = 4x2 = 1Substituting these into the original equation for y (y=x-1) givesy1 = 3y2 = 0So the 2 solutions to the equations are:x1=4y1=3andx2 = 1y2 = 0
It is: y = 4x+3
Parallel, the slope of the second equation is 4
