How do you solve x4 3x2 minus 28 equals 0?
one way is to let x^2=m, then you have an equation m^2+3m-28=0, and then you solve this quadratic equation for m, and you get: m=4, or m=-7... since m represents x^2, m can only be positive (if we are dealing with real numbers), so m=-7 is not possible solution... now if m=4, the x^2=4, and solving this equation: x=2 or x=-2
How do you solve m divided by three over four equals 28?
m / 3/4 = 28 is the same as m = 3/4 x 28 = 21
What is the first step when using cross multiplication to solve the proportion 2 divided by 12 equals m divided by18?
2/12 = m/18 ie 12 x m = 2 x 18 ...
How do you solve y equals mx plus b?
What do you mean by "solve"? Do you want to rearrange it, solving for x? That would be: x = (y - b) / m Do you want to find it's derivative with respect to x? Then the answer is: y' = m Do you want to find it's indefinite integral? That'd be: ∫y dx = mx2/2 + bx + C
How do you solve for y in the equation y equals mx plus b?
If y = mx + b, then x = (y-b)/m (for m not equal to zero).
Y equals mx plus b solve for m?
y-b/x=m

Which is the best way to solve the equation the square root of x equals m?
It depends on which variable you wish to solve for.
How many meters equals 2468 mm?
1 m = 1,000 mm x m = 2,468 mm x/1 = 2,468/1,000 cross multiply and solve for x x = 2,468/1,000 x = 2.468 m
How do you solve problems when parallel lines are cut by a transversal?
m<1=(5x-35) m<=(x+65)
How do you Solve the formula y equals mx plus b for M?
the answer is: (y-b)/x = m y = mx + b y - b = mx (y-b)/x = m

Y-b divided m equals x solve for y?
y = mx + b
How do you solve m divided by three over four equals 28?
m / 3/4 = 28 is the same as m = 3/4 x 28 = 21

How do you solve y equals mx plus b formula in math?
It depends on what you are trying to solve for. Here is a solution for x... y = mx + b y - b = mx (y - b) / m = x Note: If m is zero, then there is no solution, because the line is horizontal
