Since you have given me 4 distinct roots, the equation must be a quartic not a cubic it would be y = ax(x-2)(x+√5)(x-√5) = ax(x-2)(x^2 - 5) to find a, sub in your given point (2,20)

if a quartic has one complex zero, it will have two. They come in conjugate pairs. An easy way to make some up is to have two quadratic factors with negative discriminants: (x^2+4x+10)(3x^2-8x+7) = 3x^4+4x^3+5x^2-52x+70 you can easily make up others.

You're right, it is a W-shape, and in this case, it is more like a flattened parabola. The curve never touched the x-axis, so there are no real roots. In other words, all four roots are complex. Are you familiar with solving a quartic? and working with complex numbers?

Let C = # chickens and G = # goats. 2C + 4G = 56 C + G = 22 Multiply second equation by 2 and subtract it from the first equation. 2G = 12 G = 6 Insert that value into the first equation and solve for C. Check by inserting both values into the second equation.

One of the "think outside the box" problems in my math work is really challenging me. I need to write and equation expressing: 8 cos theta + 15 sin theta as a single sinusoid I tried graphing to no avail and there is nothing in my textbook about turning an equation like that ...

no. Write the equation in slope intercept form y=mx+b you know the slope is 1 (from the given equation). y=x+b but it contains the point 2,2 2=2+b and b then is zero. the equation is ... y=x

TAke the second equation, where x=50-6y, put that in for x in the first equation, and then solve for y. Once y is known, you can solve either equation for x.

You left out information in your equation. The equation I find for this is D=sqrt(13h). The equation in your book may be differnt. Solve for h D^2=13h h=(D^2)/13

I assume the second equation is x+4y=7 subtract the first equation from the second 6y=6 that gives you y. Put that y into either equation, solve for x.

subtract equation 2 from equation 1 8x=16 solve for x Then put that value of x into either equation, solve for y.

Subtracting the first equation from the second gives you: t-1 = (t-1)x Therefore x = 1. The first equation tells you that y = 0. The third equation requires that 1 + t = 3 t = 2

This is very simple. All you have to do is put what is equal to x in the second equation (31-6y) in for the x in the first equation giving you the equation 3(31-6y)+8y=33 Solve for the y with this equation then plug that answer into either of the equations to get x. Let me ...

Multiply 1st equation by 5, and the 2nd equation by 3. Then add the two equations. This will eliminate the y variable. Take the value you get for x and substitute that value in either equation and solve for y.

absolute means global. It's possible to have several relative extrema, and some, all, or none may be absolute extrema. A parabola has one relative extremum, which is absolute. A cubic such as y=(x-1)(x-2)(x-3) has two relative extrema, but no absolutes at all, since the ...

math, algebra
How do I solve for the following: Directions solve each literal equation for the individual variable. 2x + 3y -6 (for x ) Linear equation It has to equal something. What you have is a statement, not an equation.
