the negative variable would mean the opposite of. so therefore if u have -x= 4 ur answer would be the opposite of four which is negative 4.
x=2 because 9-(14)=-5
You solve an inequality in the same way as you would solve an equality (equation). The only difference is that if you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality sign. Thus, if you have -3x < 9 to find x, you need to divide by -3. That is a negative number so -3x/(-3) > 9/(-3) reverse inequality x > -3
given: x - 4 = -y or, -y = x - 4 or, y = -(x - 4) or y = -x + 4 or y = 4 - x i.e. for x > 4, the equation x - 4 = -y is true.
positive X positive = positive positive X negative = negative negative X positive = negative negative X negative = positive
e-x = 6Take the natural log of both sides:ln(e-x) = ln(6)-x = ln(6)x = -ln(6)So x = -ln(6), which is about -1.792.
-e^(-x) or negative e to the negative x this is because you multiply the function (e) by: 1 / (the derivative of the power ... in this case: -1) e^(-x) * (1/-1) = -e^(-x) Don't forget to add your constant!

- e^- X
d/dx (e-x) = -e-x
if you get a -4 x -3 you would get 12 because a negative and a negative will give you a positive.
Your question is not very clear. Are you asking: solve for x where negative 4 over x equals negative 20. x equals 1/5 (one fifth)
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
First, solve for y.y=-8xif x=2, then y=-16.
x2=-81take the square root of both sidessince 81 is negative you need to take 81 times i when i=-1 then solve as the square root of 81. your answer is x=9i
x + 1= -y implies x - y = 1
f(x)=3x-2,X E N
