If the question is what is the product of (8x^5-5x)(7x^3) you can find this by using the FOIL method. i.e-(8x^5)(7x^3)-(5x)(7x^3)= 56x^5+3-35x1+3= 56x^8-35x^4

Speed of gravity: 9.8meters/second Given 0.02 seconds, you can use conversion method. 9.8m/s*0.02seconds=0.196meters

This is a system of equations. x-y=8 x+y=-2 The easiest way to solve would be the elimination method because it is already set up; if you add the equations, the y cancels out and gives you: 2x=6 Further, x=3 Given x you can find y in any equation above; x-y=8 Substitute the 3:...

Anonymous is right. m is the slope of the line and b is the y intercept. So the graph will have a negative slope of (rise/run) -2/3 and it will cross the axis at y=45

Well, you could multiply everything by 100 to get an easier function: y=-3x^2+14x+143 in which you could try and use the quadratic theorem [-b +/- sqrt(b^2-4ac)]/2a Giving you: -14 +/- sqrt(196-(-1716)/-60 [-14 +/- sqrt(1912) ]/-6 You cant simplify too much. But you get the id...
