What is the Answers to 4(2x plus 5y)?
8x + 20y
What is equal to the square root of 8xy2 x the square root of 20y?
sqrt(8xy2) * sqrt(20y) = 2y*sqrt(2x)*sqrt(20y) = 4y*sqrt(x)*sqrt(10y) = 4y*sqrt(10xy)
What is the y intercept of the line 2x plus 5y equals 20?
2X + 5Y = 205Y = - 2X + 20Y = (- 2/5)X + 4================now, reading off the function,Y intercept = 4===========
What is the correct way to write the solution of 2x - 5y equals 9 and 8x - 20y equals 5?
It has no solution!!!The two equations contradict.If you recast the first in terms of x2x-5y=92x=5y+9x=2.5y+4.5Then substitute for x in the second equation8x-20y=58(2.5y+4.5)-20y=520y+36-20y=536=5 (False)which is not true - so the equations have differing values for x and/or y and so are not solveable.
How do you solve 8x plus 20y equals -80?
It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
